+For example, let's say that you want to use <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>, but with some custom settings not used in the included `ORJSONResponse` class.

+Let's say you want it to return indented and formatted JSON, so you want to use the orjson option `orjson.OPT_INDENT_2`.

+### Breaking Changes - Fixes
+
+* 🐛 Fix `response_model` not invalidating `None`. PR [#2725](https://github.com/tiangolo/fastapi/pull/2725) by [@hukkin](https://github.com/hukkin).
+
+If you are using `response_model` with some type that doesn't include `None` but the function is returning `None`, it will now raise an internal server error, because you are returning invalid data that violates the contract in `response_model`. Before this release it would allow breaking that contract returning `None`.
+
+For example, if you have an app like this:
+
+```Python
+from fastapi import FastAPI
+from pydantic import BaseModel
+
+class Item(BaseModel):
+    name: str
+    price: Optional[float] = None
+    owner_ids: Optional[List[int]] = None
+
+app = FastAPI()
+
+@app.get("/items/invalidnone", response_model=Item)
+def get_invalid_none():
+    return None
+```
+
+...calling the path `/items/invalidnone` will raise an error, because `None` is not a valid type for the `response_model` declared with `Item`.
+
+You could also be implicitly returning `None` without realizing, for example:
+
+```Python
+from fastapi import FastAPI
+from pydantic import BaseModel
+
+class Item(BaseModel):
+    name: str
+    price: Optional[float] = None
+    owner_ids: Optional[List[int]] = None
+
+app = FastAPI()
+
+@app.get("/items/invalidnone", response_model=Item)
+def get_invalid_none():
+    if flag:
+        return {"name": "foo"}
+    # if flag is False, at this point the function will implicitly return None
+```
+
+If you have *path operations* using `response_model` that need to be allowed to return `None`, make it explicit in `response_model` using `Union[Something, None]`:
+
+```Python
+from typing import Union
+
+from fastapi import FastAPI
+from pydantic import BaseModel
+
+class Item(BaseModel):
+    name: str
+    price: Optional[float] = None
+    owner_ids: Optional[List[int]] = None
+
+app = FastAPI()
+
+@app.get("/items/invalidnone", response_model=Union[Item, None])
+def get_invalid_none():
+    return None
+```
+
+This way the data will be correctly validated, you won't have an internal server error, and the documentation will also reflect that this *path operation* could return `None` (or `null` in JSON).

+FastAPI یک وب فریم‌ورک مدرن و سریع (با کارایی بالا) برای ایجاد APIهای متنوع (وب، وب‌سوکت و غبره) با زبان پایتون نسخه +۳.۶ است. این فریم‌ورک با رعایت کامل راهنمای نوع داده (Type Hint) ایجاد شده است.
 
-FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints.
+ویژگی‌های کلیدی این فریم‌ورک عبارتند از:
 
-The key features are:
+* **<abbr title="Fast">سرعت</abbr>**: کارایی بسیار بالا و قابل مقایسه با  **NodeJS** و **Go** (با تشکر از Starlette و Pydantic). [یکی از سریع‌ترین فریم‌ورک‌های پایتونی موجود](#performance).
 
-* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance).
+* **<abbr title="Fast to code">کدنویسی سریع</abbr>**: افزایش ۲۰۰ تا ۳۰۰ درصدی سرعت توسعه فابلیت‌های جدید. *
+* **<abbr title="Fewer bugs">باگ کمتر</abbr>**: کاهش ۴۰ درصدی خطاهای انسانی (برنامه‌نویسی). *
+* **<abbr title="Intuitive">غریزی</abbr>**: پشتیبانی فوق‌العاده در محیط‌های توسعه یکپارچه (IDE). <abbr title="یا اتوکامپلیت، اتوکامپلشن، اینتلیسنس">تکمیل</abbr> در همه بخش‌های کد. کاهش زمان رفع باگ.
+* **<abbr title="Easy">آسان</abbr>**: طراحی شده برای یادگیری و استفاده آسان. کاهش زمان مورد نیاز برای مراجعه به مستندات.
+* **<abbr title="Short">کوچک</abbr>**: کاهش تکرار در کد. چندین قابلیت برای هر پارامتر (منظور پارامترهای ورودی تابع هندلر می‌باشد، به بخش <a href="https://fastapi.tiangolo.com/#recap">خلاصه</a> در همین صفحه مراجعه شود). باگ کمتر.
+* **<abbr title="Robust">استوار</abbr>**: ایجاد کدی آماده برای استفاده در محیط پروداکشن و تولید خودکار <abbr title="Interactive documentation">مستندات تعاملی</abbr>
+* **<abbr title="Standards-based">مبتنی بر استانداردها</abbr>**: مبتنی بر (و منطبق با) استانداردهای متن باز مربوط به API: <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> (سوگر سابق) و <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Schema</a>.
 
-* **Fast to code**: Increase the speed to develop features by about 200% to 300%. *
-* **Fewer bugs**: Reduce about 40% of human (developer) induced errors. *
-* **Intuitive**: Great editor support. <abbr title="also known as auto-complete, autocompletion, IntelliSense">Completion</abbr> everywhere. Less time debugging.
-* **Easy**: Designed to be easy to use and learn. Less time reading docs.
-* **Short**: Minimize code duplication. Multiple features from each parameter declaration. Fewer bugs.
-* **Robust**: Get production-ready code. With automatic interactive documentation.
-* **Standards-based**: Based on (and fully compatible with) the open standards for APIs: <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> (previously known as Swagger) and <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Schema</a>.

-Coming back to the previous code example, **FastAPI** will:
+به مثال قبلی باز می‌گردیم، در این مثال **FastAPI** موارد زیر را انجام می‌دهد:
 
-* Validate that there is an `item_id` in the path for `GET` and `PUT` requests.
-* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests.
-    * If it is not, the client will see a useful, clear error.
-* Check if there is an optional query parameter named `q` (as in `http://127.0.0.1:8000/items/foo?q=somequery`) for `GET` requests.
-    * As the `q` parameter is declared with `= None`, it is optional.
-    * Without the `None` it would be required (as is the body in the case with `PUT`).
-* For `PUT` requests to `/items/{item_id}`, Read the body as JSON:
-    * Check that it has a required attribute `name` that should be a `str`.
-    * Check that it has a required attribute `price` that has to be a `float`.
-    * Check that it has an optional attribute `is_offer`, that should be a `bool`, if present.
-    * All this would also work for deeply nested JSON objects.
-* Convert from and to JSON automatically.
-* Document everything with OpenAPI, that can be used by:
-    * Interactive documentation systems.
-    * Automatic client code generation systems, for many languages.
-* Provide 2 interactive documentation web interfaces directly.
+* اعتبارسنجی اینکه پارامتر `item_id` در مسیر درخواست‌های `GET` و `PUT` موجود است .
+* اعتبارسنجی اینکه پارامتر `item_id` در درخواست‌های `GET` و `PUT` از نوع `int` است.
+    * اگر غیر از این موارد باشد، سرویس‌گیرنده خطای مفید و مشخصی دریافت خواهد کرد.
+* بررسی وجود پارامتر پرسمان اختیاری `q` (مانند `http://127.0.0.1:8000/items/foo?q=somequery`) در درخواست‌های `GET`.
+    * از آنجا که پارامتر `q` با  `= None` مقداردهی شده است, این پارامتر اختیاری است.
+    * اگر از مقدار اولیه `None` استفاده نکنیم، این پارامتر الزامی خواهد بود (همانند بدنه درخواست در درخواست `PUT`).
+* برای درخواست‌های `PUT` به آدرس `/items/{item_id}`, بدنه درخواست باید از نوع JSON تعریف شده باشد:
+    * بررسی اینکه بدنه شامل فیلدی با نام `name` و از نوع `str` است.
+    * بررسی اینکه بدنه شامل فیلدی با نام `price` و از نوع `float` است.
+    * بررسی اینکه بدنه شامل فیلدی اختیاری با نام `is_offer` است, که در صورت وجود باید از نوع `bool` باشد.
+    * تمامی این موارد برای اشیاء JSON در هر عمقی قابل بررسی می‌باشد.
+* تبدیل از/به JSON به صورت خودکار.
+* مستندسازی همه چیز با استفاده از OpenAPI, که می‌توان از آن برای موارد زیر استفاده کرد:
+    * سیستم مستندات تعاملی.
+    * تولید خودکار کد سرویس‌گیرنده‌ در زبان‌های برنامه‌نویسی بیشمار.
+* فراهم سازی ۲ مستند تعاملی مبتنی بر وب به صورت پیش‌فرض .

-La plupart des frameworks Python existants (y compris Flask et Django) ont été créés avant que les nouvelles fonctionnalités asynchrones de Python n'existent. Donc, les façons dont ils peuvent être déployés supportent l'exécution parallèle  et une ancienne forme d'exécution asynchrone qui n'est pas aussi puissante que les nouvelles fonctionnalités de Python.

+# Déploiement - Intro
+
+Le déploiement d'une application **FastAPI** est relativement simple.
+
+## Que signifie le déploiement
+
+**Déployer** une application signifie effectuer les étapes nécessaires pour la rendre **disponible pour les
+utilisateurs**.
+
+Pour une **API Web**, cela implique normalement de la placer sur une **machine distante**, avec un **programme serveur**
+qui offre de bonnes performances, une bonne stabilité, _etc._, afin que vos **utilisateurs** puissent **accéder** à
+l'application efficacement et sans interruption ni problème.
+
+Ceci contraste avec les étapes de **développement**, où vous êtes constamment en train de modifier le code, de le casser
+et de le réparer, d'arrêter et de redémarrer le serveur de développement, _etc._
+
+## Stratégies de déploiement
+
+Il existe plusieurs façons de procéder, en fonction de votre cas d'utilisation spécifique et des outils que vous
+utilisez.
+
+Vous pouvez **déployer un serveur** vous-même en utilisant une combinaison d'outils, vous pouvez utiliser un **service
+cloud** qui fait une partie du travail pour vous, ou encore d'autres options possibles.
+
+Je vais vous montrer certains des principaux concepts que vous devriez probablement avoir à l'esprit lors du déploiement
+d'une application **FastAPI** (bien que la plupart de ces concepts s'appliquent à tout autre type d'application web).
+
+Vous verrez plus de détails à avoir en tête et certaines des techniques pour le faire dans les sections suivantes. ✨

+# Histoire, conception et avenir
+
+Il y a quelque temps, <a href="https://github.com/tiangolo/fastapi/issues/3#issuecomment-454956920" class="external-link" target="_blank">un utilisateur de **FastAPI** a demandé</a> :
+
+> Quelle est l'histoire de ce projet ? Il semble être sorti de nulle part et est devenu génial en quelques semaines [...].
+
+Voici un petit bout de cette histoire.
+
+## Alternatives
+
+Je crée des API avec des exigences complexes depuis plusieurs années (Machine Learning, systèmes distribués, jobs asynchrones, bases de données NoSQL, etc), en dirigeant plusieurs équipes de développeurs.
+
+Dans ce cadre, j'ai dû étudier, tester et utiliser de nombreuses alternatives.
+
+L'histoire de **FastAPI** est en grande partie l'histoire de ses prédécesseurs.
+
+Comme dit dans la section [Alternatives](alternatives.md){.internal-link target=\_blank} :
+
+<blockquote markdown="1">
+
+**FastAPI** n'existerait pas sans le travail antérieur d'autres personnes.
+
+Il y a eu de nombreux outils créés auparavant qui ont contribué à inspirer sa création.
+
+J'ai évité la création d'un nouveau framework pendant plusieurs années. J'ai d'abord essayé de résoudre toutes les fonctionnalités couvertes par **FastAPI** en utilisant de nombreux frameworks, plug-ins et outils différents.
+
+Mais à un moment donné, il n'y avait pas d'autre option que de créer quelque chose qui offre toutes ces fonctionnalités, en prenant les meilleures idées des outils précédents, et en les combinant de la meilleure façon possible, en utilisant des fonctionnalités du langage qui n'étaient même pas disponibles auparavant (annotations de type pour Python 3.6+).
+
+</blockquote>
+
+## Recherche
+
+En utilisant toutes les alternatives précédentes, j'ai eu la chance d'apprendre de toutes, de prendre des idées, et de les combiner de la meilleure façon que j'ai pu trouver pour moi-même et les équipes de développeurs avec lesquelles j'ai travaillé.
+
+Par exemple, il était clair que l'idéal était de se baser sur les annotations de type Python standard.
+
+De plus, la meilleure approche était d'utiliser des normes déjà existantes.
+
+Ainsi, avant même de commencer à coder **FastAPI**, j'ai passé plusieurs mois à étudier les spécifications d'OpenAPI, JSON Schema, OAuth2, etc. Comprendre leurs relations, leurs similarités et leurs différences.
+
+## Conception
+
+Ensuite, j'ai passé du temps à concevoir l'"API" de développeur que je voulais avoir en tant qu'utilisateur (en tant que développeur utilisant FastAPI).
+
+J'ai testé plusieurs idées dans les éditeurs Python les plus populaires : PyCharm, VS Code, les éditeurs basés sur Jedi.
+
+D'après la dernière <a href="https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools" class="external-link" target="_blank">Enquête Développeurs Python</a>, cela couvre environ 80% des utilisateurs.
+
+Cela signifie que **FastAPI** a été spécifiquement testé avec les éditeurs utilisés par 80% des développeurs Python. Et comme la plupart des autres éditeurs ont tendance à fonctionner de façon similaire, tous ses avantages devraient fonctionner pour pratiquement tous les éditeurs.
+
+Ainsi, j'ai pu trouver les meilleurs moyens de réduire autant que possible la duplication du code, d'avoir la complétion partout, les contrôles de type et d'erreur, etc.
+
+Le tout de manière à offrir la meilleure expérience de développement à tous les développeurs.
+
+## Exigences
+
+Après avoir testé plusieurs alternatives, j'ai décidé que j'allais utiliser <a href="https://pydantic-docs.helpmanual.io/" class="external-link" target="_blank">**Pydantic**</a> pour ses avantages.
+
+J'y ai ensuite contribué, pour le rendre entièrement compatible avec JSON Schema, pour supporter différentes manières de définir les déclarations de contraintes, et pour améliorer le support des éditeurs (vérifications de type, autocomplétion) sur la base des tests effectués dans plusieurs éditeurs.
+
+Pendant le développement, j'ai également contribué à <a href="https://www.starlette.io/" class="external-link" target="_blank">**Starlette**</a>, l'autre exigence clé.
+
+## Développement
+
+Au moment où j'ai commencé à créer **FastAPI** lui-même, la plupart des pièces étaient déjà en place, la conception était définie, les exigences et les outils étaient prêts, et la connaissance des normes et des spécifications était claire et fraîche.
+
+## Futur
+
+À ce stade, il est déjà clair que **FastAPI** et ses idées sont utiles pour de nombreuses personnes.
+
+Elle a été préférée aux solutions précédentes parce qu'elle convient mieux à de nombreux cas d'utilisation.
+
+De nombreux développeurs et équipes dépendent déjà de **FastAPI** pour leurs projets (y compris moi et mon équipe).
+
+Mais il y a encore de nombreuses améliorations et fonctionnalités à venir.
+
+**FastAPI** a un grand avenir devant lui.
+
+Et [votre aide](help-fastapi.md){.internal-link target=\_blank} est grandement appréciée.

+# Tutorial - Pedoman Pengguna - Pengenalan
+
+Tutorial ini menunjukan cara menggunakan ***FastAPI*** dengan semua fitur-fiturnya, tahap demi tahap.
+
+Setiap bagian dibangun secara bertahap dari bagian sebelumnya, tetapi terstruktur untuk memisahkan banyak topik, sehingga kamu bisa secara langsung menuju ke topik spesifik untuk menyelesaikan kebutuhan API tertentu.
+
+Ini juga dibangun untuk digunakan sebagai referensi yang akan datang.
+
+Sehingga kamu dapat kembali lagi dan mencari apa yang kamu butuhkan dengan tepat.
+
+## Jalankan kode
+
+Semua blok-blok kode dapat dicopy dan digunakan langsung (Mereka semua sebenarnya adalah file python yang sudah teruji).
+
+Untuk menjalankan setiap contoh, copy kode ke file `main.py`, dan jalankan `uvicorn` dengan:
+
+<div class="termy">
+
+```console
+$ uvicorn main:app --reload
+
+<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
+<span style="color: green;">INFO</span>:     Started reloader process [28720]
+<span style="color: green;">INFO</span>:     Started server process [28722]
+<span style="color: green;">INFO</span>:     Waiting for application startup.
+<span style="color: green;">INFO</span>:     Application startup complete.
+```
+
+</div>
+
+**SANGAT disarankan** agar kamu menulis atau meng-copy kode, meng-editnya dan menjalankannya secara lokal.
+
+Dengan menggunakannya di dalam editor, benar-benar memperlihatkan manfaat dari FastAPI, melihat bagaimana sedikitnya kode yang harus kamu tulis, semua pengecekan tipe, pelengkapan otomatis, dll.
+
+---
+
+## Install FastAPI
+
+Langkah pertama adalah dengan meng-install FastAPI.
+
+Untuk tutorial, kamu mungkin hendak meng-instalnya dengan semua pilihan fitur dan dependensinya:
+
+<div class="termy">
+
+```console
+$ pip install "fastapi[all]"
+
+---> 100%
+```
+
+</div>
+
+...yang juga termasuk `uvicorn`, yang dapat kamu gunakan sebagai server yang menjalankan kodemu.
+
+!!! catatan

+# NoSQL (分散 / ビッグデータ) Databases
+
+**FastAPI** はあらゆる <abbr title="分散データベース (Big Data)や 'Not Only SQL'">NoSQL</abbr>と統合することもできます。
+
+ここでは<abbr title="ここでのドキュメントとは、キーと値を持つJSONオブジェクト（ディクショナリー）をあらわし、これらの値は他のJSONオブジェクトや配列（リスト）、数値、文字列、真偽値などにすることができます。">ドキュメント</abbr>ベースのNoSQLデータベースである**<a href="https://www.couchbase.com/" class="external-link" target="_blank">Couchbase</a>**を使用した例を見てみましょう。
+
+他にもこれらのNoSQLデータベースを利用することが出来ます:
+
+* **MongoDB**
+* **Cassandra**
+* **CouchDB**
+* **ArangoDB**
+* **ElasticSearch** など。
+
+!!! tip "豆知識"
+    **FastAPI**と**Couchbase**を使った公式プロジェクト・ジェネレータがあります。すべて**Docker**ベースで、フロントエンドやその他のツールも含まれています: <a href="https://github.com/tiangolo/full-stack-fastapi-couchbase" class="external-link" target="_blank">https://github.com/tiangolo/full-stack-fastapi-couchbase</a>
+
+## Couchbase コンポーネントの Import
+
+まずはImportしましょう。今はその他のソースコードに注意を払う必要はありません。
+
+```Python hl_lines="3-5"
+{!../../../docs_src/nosql_databases/tutorial001.py!}
+```
+
+## "document type" として利用する定数の定義
+
+documentで利用する固定の`type`フィールドを用意しておきます。
+
+これはCouchbaseで必須ではありませんが、後々の助けになるベストプラクティスです。
+
+```Python hl_lines="9"
+{!../../../docs_src/nosql_databases/tutorial001.py!}
+```
+
+## `Bucket` を取得する関数の追加
+
+**Couchbase**では、bucketはdocumentのセットで、様々な種類のものがあります。
+
+Bucketは通常、同一のアプリケーション内で互いに関係を持っています。
+
+リレーショナルデータベースの世界でいう"database"(データベースサーバではなく特定のdatabase)と類似しています。
+
+**MongoDB** で例えると"collection"と似た概念です。
+
+次のコードでは主に `Bucket` を利用してCouchbaseを操作します。
+
+この関数では以下の処理を行います:
+
+* **Couchbase** クラスタ(1台の場合もあるでしょう)に接続
+    * タイムアウトのデフォルト値を設定
+* クラスタで認証を取得
+* `Bucket` インスタンスを取得
+    * タイムアウトのデフォルト値を設定
+* 作成した`Bucket`インスタンスを返却
+
+```Python hl_lines="12-21"
+{!../../../docs_src/nosql_databases/tutorial001.py!}
+```
+
+## Pydantic モデルの作成
+
+**Couchbase**のdocumentは実際には単にJSONオブジェクトなのでPydanticを利用してモデルに出来ます。
+
+### `User` モデル
+
+まずは`User`モデルを作成してみましょう:
+
+```Python hl_lines="24-28"
+{!../../../docs_src/nosql_databases/tutorial001.py!}
+```
+
+このモデルは*path operation*に使用するので`hashed_password`は含めません。
+
+### `UserInDB` モデル
+
+それでは`UserInDB`モデルを作成しましょう。
+
+こちらは実際にデータベースに保存されるデータを保持します。
+
+`User`モデルの持つ全ての属性に加えていくつかの属性を追加するのでPydanticの`BaseModel`を継承せずに`User`のサブクラスとして定義します:
+
+```Python hl_lines="31-33"
+{!../../../docs_src/nosql_databases/tutorial001.py!}
+```
+
+!!! note "備考"
+    データベースに保存される`hashed_password`と`type`フィールドを`UserInDB`モデルに保持させていることに注意してください。
+
+    しかしこれらは(*path operation*で返却する)一般的な`User`モデルには含まれません
+
+## user の取得
+
+それでは次の関数を作成しましょう:
+
+* username を取得する
+* username を利用してdocumentのIDを生成する
+* 作成したIDでdocumentを取得する
+* documentの内容を`UserInDB`モデルに設定する
+
+*path operation関数*とは別に、`username`(またはその他のパラメータ)からuserを取得することだけに特化した関数を作成することで、より簡単に複数の部分で再利用したり<abbr title="コードで書かれた自動テストで、他のコードが正しく動作しているかどうかをチェックするもの。">ユニットテスト</abbr>を追加することができます。
+
+```Python hl_lines="36-42"
+{!../../../docs_src/nosql_databases/tutorial001.py!}
+```
+
+### f-strings
+
+`f"userprofile::{username}"` という記載に馴染みがありませんか？これは Python の"<a href="https://docs.python.org/3/glossary.html#term-f-string" class="external-link" target="_blank">f-string</a>"と呼ばれるものです。
+
+f-stringの`{}`の中に入れられた変数は、文字列の中に展開/注入されます。
+
+### `dict` アンパック
+
+`UserInDB(**result.value)`という記載に馴染みがありませんか？<a href="https://docs.python.org/3/glossary.html#term-argument" class="external-link" target="_blank">これは`dict`の"アンパック"</a>と呼ばれるものです。
+
+これは`result.value`の`dict`からそのキーと値をそれぞれ取りキーワード引数として`UserInDB`に渡します。
+
+例えば`dict`が下記のようになっていた場合:
+
+```Python
+{
+    "username": "johndoe",
+    "hashed_password": "some_hash",
+}
+```
+
+`UserInDB`には次のように渡されます:
+
+```Python
+UserInDB(username="johndoe", hashed_password="some_hash")
+```
+
+## **FastAPI** コードの実装
+
+### `FastAPI` app の作成
+
+```Python hl_lines="46"
+{!../../../docs_src/nosql_databases/tutorial001.py!}
+```
+
+### *path operation関数*の作成
+
+私たちのコードはCouchbaseを呼び出しており、<a href="https://docs.couchbase.com/python-sdk/2.5/async-programming.html#asyncio-python-3-5" class="external-link" target="_blank">実験的なPython <code>await</code></a>を使用していないので、私たちは`async def`ではなく通常の`def`で関数を宣言する必要があります。
+
+また、Couchbaseは単一の`Bucket`オブジェクトを複数の<abbr title="プログラムによって実行される一連のコードのことで、同時に、または間隔をおいて他のコードも実行されることがあります。">スレッド</abbr>で使用しないことを推奨していますので、単に直接Bucketを取得して関数に渡すことが出来ます。
+
+```Python hl_lines="49-53"
+{!../../../docs_src/nosql_databases/tutorial001.py!}
+```
+
+## まとめ
+
+他のサードパーティ製のNoSQLデータベースを利用する場合でも、そのデータベースの標準ライブラリを利用するだけで利用できます。
+
+他の外部ツール、システム、APIについても同じことが言えます。

+# Manipulação de erros
+
+Há diversas situações em que você precisa notificar um erro a um cliente que está utilizando a sua API.
+
+Esse cliente pode ser um browser com um frontend, o código de outra pessoa, um dispositivo IoT, etc.
+
+Pode ser que você precise comunicar ao cliente que:
+
+* O cliente não tem direitos para realizar aquela operação.
+* O cliente não tem acesso aquele recurso.
+* O item que o cliente está tentando acessar não existe.
+* etc.
+
+
+Nesses casos, você normalmente retornaria um **HTTP status code** próximo ao status code na faixa do status code **400** (do 400 ao 499).
+
+Isso é bastante similar ao caso do HTTP status code 200 (do 200 ao 299). Esses "200" status codes significam que, de algum modo, houve sucesso na requisição.
+
+Os status codes na faixa dos 400 significam que houve um erro por parte do cliente.
+
+Você se lembra de todos aqueles erros (e piadas) a respeito do "**404 Not Found**"?
+
+## Use o `HTTPException`
+
+Para retornar ao cliente *responses* HTTP com erros, use o `HTTPException`.
+
+### Import `HTTPException`
+
+```Python hl_lines="1"
+{!../../../docs_src/handling_errors/tutorial001.py!}
+```
+
+### Lance o `HTTPException` no seu código.
+
+`HTTPException`, ao fundo, nada mais é do que a conjunção entre uma exceção comum do Python e informações adicionais relevantes para APIs.
+
+E porque é uma exceção do Python, você não **retorna** (return) o `HTTPException`, você lança o (raise) no seu código.
+
+Isso também significa que, se você está escrevendo uma função de utilidade, a qual você está chamando dentro da sua função de operações de caminhos, e você lança o `HTTPException` dentro da função de utilidade, o resto do seu código não será executado dentro da função de operações de caminhos. Ao contrário, o `HTTPException` irá finalizar a requisição no mesmo instante e enviará o erro HTTP oriundo do `HTTPException` para o cliente.
+
+O benefício de lançar uma exceção em vez de retornar um valor ficará mais evidente na seção sobre Dependências e Segurança.
+
+Neste exemplo, quando o cliente pede, na requisição, por um item cujo ID não existe, a exceção com o status code `404` é lançada:
+
+```Python hl_lines="11"
+{!../../../docs_src/handling_errors/tutorial001.py!}
+```
+
+### A response resultante
+
+
+Se o cliente faz uma requisição para `http://example.com/items/foo` (um `item_id` `"foo"`), esse cliente receberá um HTTP status code 200, e uma resposta JSON:
+
+
+```
+{
+  "item": "The Foo Wrestlers"
+}
+```
+
+Mas se o cliente faz uma requisição para `http://example.com/items/bar` (ou seja, um não existente `item_id "bar"`), esse cliente receberá um HTTP status code 404 (o erro "não encontrado" — *not found error*), e uma resposta JSON:
+
+```JSON
+{
+  "detail": "Item not found"
+}
+```
+
+!!! tip "Dica"
+    Quando você lançar um `HTTPException`, você pode passar qualquer valor convertível em JSON como parâmetro de `detail`, e não apenas `str`.
+
+    Você pode passar um `dict` ou um `list`, etc.
+    Esses tipos de dados são manipulados automaticamente pelo **FastAPI** e convertidos em JSON.
+
+
+## Adicione headers customizados
+
+Há certas situações em que é bastante útil poder adicionar headers customizados no HTTP error. Exemplo disso seria adicionar headers customizados para tipos de segurança.
+
+Você provavelmente não precisará utilizar esses headers diretamente no seu código.
+
+Mas caso você precise, para um cenário mais complexo, você pode adicionar headers customizados:
+
+```Python hl_lines="14"
+{!../../../docs_src/handling_errors/tutorial002.py!}
+```
+
+## Instalando manipuladores de exceções customizados
+
+Você pode adicionar manipuladores de exceção customizados com <a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">a mesma seção de utilidade de exceções presentes no Starlette</a>
+
+Digamos que você tenha uma exceção customizada `UnicornException` que você (ou uma biblioteca que você use) precise lançar (`raise`).
+
+Nesse cenário, se você precisa manipular essa exceção de modo global com o FastAPI, você pode adicionar um manipulador de exceção customizada com `@app.exception_handler()`.
+
+```Python hl_lines="5-7  13-18  24"
+{!../../../docs_src/handling_errors/tutorial003.py!}
+```
+
+Nesse cenário, se você fizer uma requisição para `/unicorns/yolo`, a *operação de caminho* vai lançar (`raise`) o `UnicornException`.
+
+Essa exceção será manipulada, contudo, pelo `unicorn_exception_handler`.
+
+Dessa forma você receberá um erro "limpo", com o HTTP status code `418` e um JSON com o conteúdo:
+
+```JSON
+{"message": "Oops! yolo did something. There goes a rainbow..."}
+```
+
+!!! note "Detalhes Técnicos"
+    Você também pode usar `from starlette.requests import Request` and `from starlette.responses import JSONResponse`.
+
+    **FastAPI** disponibiliza o mesmo `starlette.responses` através do `fastapi.responses` por conveniência ao desenvolvedor. Contudo, a maior parte das respostas disponíveis vem diretamente do Starlette. O mesmo acontece com o `Request`.
+
+## Sobrescreva o manipulador padrão de exceções
+
+**FastAPI** tem alguns manipuladores padrão de exceções.
+
+Esses manipuladores são os responsáveis por retornar o JSON padrão de respostas quando você lança (`raise`) o `HTTPException` e quando a requisição tem dados invalidos.
+
+Você pode sobrescrever esses manipuladores de exceção com os seus próprios manipuladores.
+

+}
+```
+
+você receberá a versão em texto:

+```
+
+### `RequestValidationError` vs `ValidationError`
+
+!!! warning "Aviso"
+    Você pode pular estes detalhes técnicos caso eles não sejam importantes para você neste momento.
+
+`RequestValidationError` é uma subclasse do <a href="https://pydantic-docs.helpmanual.io/#error-handling" class="external-link" target="_blank">`ValidationError`</a> existente no Pydantic.
+
+**FastAPI** faz uso dele para que você veja o erro no seu log, caso você utilize um modelo de Pydantic em `response_model`, e seus dados tenham erro.
+
+Contudo, o cliente ou usuário não terão acesso a ele. Ao contrário, o cliente receberá um "Internal Server Error" com o HTTP status code `500`.
+
+E assim deve ser porque seria um bug no seu código ter o `ValidationError` do Pydantic na sua *response*, ou em qualquer outro lugar do seu código (que não na requisição do cliente).
+
+E enquanto você conserta o bug, os clientes / usuários não deveriam ter acesso às informações internas do erro, porque, desse modo, haveria exposição de uma vulnerabilidade de segurança.
+
+Do mesmo modo, você pode sobreescrever o `HTTPException`.
+
+Por exemplo, você pode querer retornar uma *response* em *plain text* ao invés de um JSON para os seguintes erros:
+
+```Python hl_lines="3-4  9-11  22"
+{!../../../docs_src/handling_errors/tutorial004.py!}
+```
+
+!!! note "Detalhes Técnicos"
+    Você pode usar `from starlette.responses import PlainTextResponse`.
+
+    **FastAPI** disponibiliza o mesmo `starlette.responses` como `fastapi.responses`, como conveniência a você, desenvolvedor. Contudo, a maior parte das respostas disponíveis vem diretamente do Starlette.
+
+
+### Use o body do `RequestValidationError`.
+
+O `RequestValidationError` contém o `body` que ele recebeu de dados inválidos.
+
+Você pode utilizá-lo enquanto desenvolve seu app para conectar o *body* e debugá-lo, e assim retorná-lo ao usuário, etc.
+
+Tente enviar um item inválido como este:
+
+```JSON
+{
+  "title": "towel",
+  "size": "XL"
+}
+```
+
+Você receberá uma *response* informando-o de que a data é inválida, e contendo o *body* recebido:
+
+```JSON hl_lines="12-15"
+{
+  "detail": [
+    {
+      "loc": [
+        "body",
+        "size"
+      ],
+      "msg": "value is not a valid integer",
+      "type": "type_error.integer"
+    }
+  ],
+  "body": {
+    "title": "towel",
+    "size": "XL"
+  }
+}
+```
+
+#### O `HTTPException` do FastAPI vs o `HTTPException` do Starlette.
+
+O **FastAPI** tem o seu próprio `HTTPException`.
+
+E a classe de erro `HTTPException` do **FastAPI** herda da classe de erro do `HTTPException` do Starlette.
+
+A diferença entre os dois é a de que o `HTTPException` do **FastAPI** permite que você adicione *headers* que serão incluídos nas *responses*.
+
+Esses *headers* são necessários/utilizados internamente pelo OAuth 2.0 e também por outras utilidades de segurança.
+
+Portanto, você pode continuar lançando o `HTTPException` do **FastAPI** normalmente no seu código.
+
+Porém, quando você registrar um manipulador de exceção, você deve registrá-lo através do `HTTPException` do Starlette.
+
+Dessa forma, se qualquer parte do código interno, extensão ou plug-in do Starlette lançar o `HTTPException`, o seu manipulador de exceção poderá capturar esse lançamento e tratá-lo.
+
+```Python
+from starlette.exceptions import HTTPException as StarletteHTTPException
+```
+
+### Re-use os manipulares de exceção do **FastAPI**
+
+Se você quer usar a exceção em conjunto com o mesmo manipulador de exceção *default* do **FastAPI**, você pode importar e re-usar esses manipuladores de exceção do `fastapi.exception_handlers`:
+
+```Python hl_lines="2-5  15  21"
+{!../../../docs_src/handling_errors/tutorial006.py!}
+```
+
+Nesse exemplo você apenas imprime (`print`) o erro com uma mensagem expressiva. Mesmo assim, dá para pegar a ideia. Você pode usar a exceção e então apenas re-usar o manipulador de exceção *default*.

+# Parâmetros de Cabeçalho

+
+Primeiro importe `Header`:
+
+=== "Python 3.6 and above"
+
+    ```Python hl_lines="3"
+    {!> ../../../docs_src/header_params/tutorial001.py!}
+    ```

+
+## Declare parâmetros de `Header`
+
+Então declare os paramêtros de cabeçalho usando a mesma estrutura que em `Path`, `Query` e `Cookie`.
+
+O primeiro valor é o valor padrão, você pode passar todas as validações adicionais ou parâmetros de anotação:
+
+=== "Python 3.6 and above"
+
+    ```Python hl_lines="9"

+    ```
+
+!!! note "Detalhes Técnicos"
+    `Header` é uma classe "irmã" de `Path`, `Query` e `Cookie`. Ela também herda da mesma classe em comum `Param`.
+
+    Mas lembre-se que quando você importa `Query`, `Path`, `Header`, e outras de `fastapi`, elas são na verdade funções que retornam classes especiais.
+
+!!! info
+    Para declarar headers, você precisa usar `Header`, caso contrário, os parâmetros seriam interpretados como parâmetros de consulta.
+
+## Conversão automática
+
+`Header` tem algumas funcionalidades a mais em relação a `Path`, `Query` e `Cookie`.
+
+A maioria dos cabeçalhos padrão são separados pelo caractere "hífen", também conhecido como "sinal de menos" (`-`).
+
+Mas uma variável como `user-agent` é inválida em Python.
+
+Portanto, por padrão, `Header` converterá os caracteres de nomes de parâmetros de sublinhado (`_`) para hífen (`-`) para extrair e documentar os cabeçalhos.
+
+Além disso, os cabeçalhos HTTP não diferenciam maiúsculas de minúsculas, portanto, você pode declará-los com o estilo padrão do Python (também conhecido como "snake_case").
+
+Portanto, você pode usar `user_agent` como faria normalmente no código Python, em vez de precisar colocar as primeiras letras em maiúsculas como `User_Agent` ou algo semelhante.
+
+Se por algum motivo você precisar desabilitar a conversão automática de sublinhados para hífens, defina o parâmetro `convert_underscores` de `Header` para `False`:
+
+=== "Python 3.6 and above"
+
+    ```Python hl_lines="10"
+    {!> ../../../docs_src/header_params/tutorial002.py!}
+    ```
+
+=== "Python 3.10 and above"
+
+    ```Python hl_lines="8"
+    {!> ../../../docs_src/header_params/tutorial002_py310.py!}
+    ```
+
+!!! warning "Aviso"
+    Antes de definir `convert_underscores` como `False`, lembre-se de que alguns proxies e servidores HTTP não permitem o uso de cabeçalhos com sublinhados.
+
+## Cabeçalhos duplicados
+
+É possível receber cabeçalhos duplicados. Isso significa, o mesmo cabeçalho com vários valores.
+
+Você pode definir esses casos usando uma lista na declaração de tipo.
+
+Você receberá todos os valores do cabeçalho duplicado como uma `list` Python.
+
+Por exemplo, para declarar um cabeçalho de `X-Token` que pode aparecer mais de uma vez, você pode escrever:
+
+=== "Python 3.6 and above"
+
+    ```Python hl_lines="9"
+    {!> ../../../docs_src/header_params/tutorial003.py!}
+    ```
+
+=== "Python 3.9 and above"
+
+    ```Python hl_lines="9"
+    {!> ../../../docs_src/header_params/tutorial003_py39.py!}
+    ```
+
+=== "Python 3.10 and above"
+
+    ```Python hl_lines="7"
+    {!> ../../../docs_src/header_params/tutorial003_py310.py!}
+    ```
+
+Se você se comunicar com essa *operação de caminho* enviando dois cabeçalhos HTTP como:
+
+```
+X-Token: foo
+X-Token: bar
+```
+
+A resposta seria como:
+
+```JSON
+{
+    "X-Token values": [
+        "bar",
+        "foo"
+    ]
+}
+```
+
+## Recapitulando
+
+Declare cabeçalhos com `Header`, usando o mesmo padrão comum que utiliza-se em `Query`, `Path` e `Cookie`.
+
+E não se preocupe com sublinhados em suas variáveis, FastAPI cuidará da conversão deles.

+# Parâmetros de Consulta
+
+Quando você declara outros parâmetros na função que não fazem parte dos parâmetros da rota, esses parâmetros são automaticamente interpretados como parâmetros de "consulta".
+
+```Python hl_lines="9"
+{!../../../docs_src/query_params/tutorial001.py!}
+```
+
+A consulta é o conjunto de pares chave-valor que vai depois de `?` na URL, separado pelo caractere `&`.
+
+Por exemplo, na URL:
+
+```
+http://127.0.0.1:8000/items/?skip=0&limit=10
+```
+
+...os parâmetros da consulta são:
+
+* `skip`: com o valor `0`
+* `limit`: com o valor `10`
+
+Como eles são parte da URL, eles são "naturalmente" strings.
+
+Mas quando você declara eles com os tipos do Python (no exemplo acima, como `int`), eles são convertidos para aquele tipo e validados em relação a ele.
+
+Todo o processo que era aplicado para parâmetros de rota também é aplicado para parâmetros de consulta:
+
+* Suporte do editor (obviamente)
+* <abbr title="convertendo uma string que vem de um request HTTP em um dado Python">"Parsing"</abbr> de dados
+* Validação de dados
+* Documentação automática
+
+## Valores padrão
+
+Como os parâmetros de consulta não são uma parte fixa da rota, eles podem ser opcionais e podem ter valores padrão.
+
+No exemplo acima eles tem valores padrão de `skip=0` e `limit=10`.
+
+Então, se você for até a URL:
+
+```
+http://127.0.0.1:8000/items/
+```
+
+Seria o mesmo que ir para:
+
+```
+http://127.0.0.1:8000/items/?skip=0&limit=10
+```
+
+Mas, se por exemplo você for para:
+
+```
+http://127.0.0.1:8000/items/?skip=20
+```
+
+Os valores dos parâmetros na sua função serão:
+
+* `skip=20`: Por que você definiu isso na URL
+* `limit=10`: Por que esse era o valor padrão
+
+## Parâmetros opcionais
+
+Da mesma forma, você pode declarar parâmetros de consulta opcionais, definindo o valor padrão para `None`:
+
+=== "Python 3.6 and above"
+
+    ```Python hl_lines="9"
+    {!> ../../../docs_src/query_params/tutorial002.py!}
+    ```
+
+=== "Python 3.10 and above"
+
+    ```Python hl_lines="7"
+    {!> ../../../docs_src/query_params/tutorial002_py310.py!}
+    ```
+
+Nesse caso, o parâmetro da função `q` será opcional, e `None` será o padrão.
+
+!!! check "Verificar"
+    Você também pode notar que o **FastAPI** é esperto o suficiente para perceber que o parâmetro da rota `item_id` é um parâmetro da rota, e `q` não é, portanto, `q` é o parâmetro de consulta.
+
+
+## Conversão dos tipos de parâmetros de consulta
+
+Você também pode declarar tipos `bool`, e eles serão convertidos:
+
+=== "Python 3.6 and above"
+
+    ```Python hl_lines="9"
+    {!> ../../../docs_src/query_params/tutorial003.py!}
+    ```
+
+=== "Python 3.10 and above"
+
+    ```Python hl_lines="7"
+    {!> ../../../docs_src/query_params/tutorial003_py310.py!}
+    ```
+
+Nesse caso, se você for para:
+
+```
+http://127.0.0.1:8000/items/foo?short=1
+```
+
+ou
+
+```
+http://127.0.0.1:8000/items/foo?short=True
+```
+
+ou
+
+```
+http://127.0.0.1:8000/items/foo?short=true
+```
+
+ou
+
+```
+http://127.0.0.1:8000/items/foo?short=on
+```
+
+ou
+
+```
+http://127.0.0.1:8000/items/foo?short=yes
+```
+
+ou qualquer outra variação (tudo em maiúscula, primeira letra em maiúscula, etc), a sua função vai ver o parâmetro `short` com um valor `bool` de `True`. Caso contrário `False`.
+
+## Múltiplos parâmetros de rota e consulta
+
+Você pode declarar múltiplos parâmetros de rota e parâmetros de consulta ao mesmo tempo, o **FastAPI** vai saber o quê é o quê.
+
+E você não precisa declarar eles em nenhuma ordem específica.
+
+Eles serão detectados pelo nome:
+
+=== "Python 3.6 and above"
+
+    ```Python hl_lines="8  10"
+    {!> ../../../docs_src/query_params/tutorial004.py!}
+    ```
+
+=== "Python 3.10 and above"
+
+    ```Python hl_lines="6  8"
+    {!> ../../../docs_src/query_params/tutorial004_py310.py!}
+    ```
+
+## Parâmetros de consulta obrigatórios
+
+Quando você declara um valor padrão para parâmetros que não são de rota (até agora, nós vimos apenas parâmetros de consulta), então eles não são obrigatórios.
+
+Caso você não queira adicionar um valor específico mas queira apenas torná-lo opcional, defina o valor padrão como `None`.
+
+Porém, quando você quiser fazer com que o parâmetro de consulta seja obrigatório, você pode simplesmente não declarar nenhum valor como padrão.
+
+```Python hl_lines="6-7"
+{!../../../docs_src/query_params/tutorial005.py!}
+```
+
+Aqui o parâmetro de consulta `needy` é um valor obrigatório, do tipo `str`.
+
+Se você abrir no seu navegador a URL:
+
+```
+http://127.0.0.1:8000/items/foo-item
+```
+
+... sem adicionar o parâmetro obrigatório `needy`, você verá um erro como:
+
+```JSON
+{
+    "detail": [
+        {
+            "loc": [
+                "query",
+                "needy"
+            ],
+            "msg": "field required",
+            "type": "value_error.missing"
+        }
+    ]
+}
+```
+
+Como `needy` é um parâmetro obrigatório, você precisaria defini-lo na URL:
+
+```
+http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
+```
+
+...isso deve funcionar:
+
+```JSON
+{
+    "item_id": "foo-item",
+    "needy": "sooooneedy"
+}
+```
+
+E claro, você pode definir alguns parâmetros como obrigatórios, alguns possuindo um valor padrão, e outros sendo totalmente opcionais:
+
+=== "Python 3.6 and above"
+
+    ```Python hl_lines="10"
+    {!> ../../../docs_src/query_params/tutorial006.py!}
+    ```
+
+=== "Python 3.10 and above"
+
+    ```Python hl_lines="8"
+    {!> ../../../docs_src/query_params/tutorial006_py310.py!}
+    ```
+Nesse caso, existem 3 parâmetros de consulta:
+
+* `needy`, um `str` obrigatório.
+* `skip`, um `int` com o valor padrão `0`.
+* `limit`, um `int` opcional.
+
+!!! tip "Dica"
+    Você também poderia usar `Enum` da mesma forma que com [Path Parameters](path-params.md#predefined-values){.internal-link target=_blank}.

+# Segurança - Primeiros Passos
+
+Vamos imaginar que você tem a sua API **backend** em algum domínio.
+
+E você tem um **frontend** em outro domínio ou em um path diferente no mesmo domínio (ou em uma aplicação mobile).
+
+E você quer uma maneira de o frontend autenticar o backend, usando um **username** e **senha**.
+
+Nós podemos usar o **OAuth2** junto com o **FastAPI**.
+
+Mas, vamos poupar-lhe o tempo de ler toda a especificação apenas para achar as pequenas informações que você precisa.
+
+Vamos usar as ferramentas fornecidas pela **FastAPI** para lidar com segurança.
+
+## Como Parece
+
+Vamos primeiro usar o código e ver como funciona, e depois voltaremos para entender o que está acontecendo.
+
+## Crie um `main.py`
+Copie o exemplo em um arquivo `main.py`:
+
+```Python
+{!../../../docs_src/security/tutorial001.py!}
+```
+
+## Execute-o
+
+!!! informação
+	Primeiro, instale <a href="https://andrew-d.github.io/python-multipart/" class="external-link" target="_blank">`python-multipart`</a>.
+
+	Ex: `pip install python-multipart`.
+
+	Isso ocorre porque o **OAuth2** usa "dados de um formulário" para mandar o **username** e **senha**.
+
+Execute esse exemplo com:
+
+<div class="termy">
+
+```console
+$ uvicorn main:app --reload
+
+<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
+```
+
+</div>
+
+## Verifique-o
+
+Vá até a documentação interativa em: <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.
+
+Você verá algo deste tipo:
+
+<img src="/img/tutorial/security/image01.png">
+
+!!! marque o "botão de Autorizar!"
+	Você já tem um novo "botão de autorizar!".
+
+	E seu *path operation* tem um pequeno cadeado no canto superior direito que você pode clicar.
+
+E se você clicar, você terá um pequeno formulário de autorização para digitar o `username` e `senha` (e outros campos opcionais):
+
+<img src="/img/tutorial/security/image02.png">
+
+!!! nota
+	Não importa o que você digita no formulário, não vai funcionar ainda. Mas nós vamos chegar lá.
+
+Claro que este não é o frontend para os usuários finais, mas é uma ótima ferramenta automática para documentar interativamente toda sua API.
+
+Pode ser usado pelo time de frontend (que pode ser você no caso).
+
+Pode ser usado por aplicações e sistemas third party (de terceiros).
+
+E também pode ser usada por você mesmo, para debugar, checar e testar a mesma aplicação.
+
+## O Fluxo da `senha`
+
+Agora vamos voltar um pouco e entender o que é isso tudo.
+
+O "fluxo" da `senha` é um dos caminhos ("fluxos") definidos no OAuth2, para lidar com a segurança e autenticação.
+
+OAuth2 foi projetado para que o backend ou a API pudesse ser independente do servidor que autentica o usuário.
+
+Mas nesse caso, a mesma aplicação **FastAPI** irá lidar com a API e a autenticação.
+
+Então, vamos rever de um ponto de vista simplificado:
+
+* O usuário digita o `username` e a `senha` no frontend e aperta `Enter`.
+* O frontend (rodando no browser do usuário) manda o `username` e a `senha` para uma URL específica na sua API (declarada com `tokenUrl="token"`).
+* A API checa aquele `username` e `senha`, e responde com um "token" (nós não implementamos nada disso ainda).
+	* Um "token" é apenas uma string com algum conteúdo que nós podemos utilizar mais tarde para verificar o usuário.
+	* Normalmente, um token é definido para expirar depois de um tempo.
+		* Então, o usuário terá que se logar de novo depois de um tempo.
+		* E se o token for roubado, o risco é menor. Não é como se fosse uma chave permanente que vai funcionar para sempre (na maioria dos casos).
+	* O frontend armazena aquele token temporariamente em algum lugar.
+	* O usuário clica no frontend para ir à outra seção daquele frontend do aplicativo web.
+	* O frontend precisa buscar mais dados daquela API.
+		* Mas precisa de autenticação para aquele endpoint em específico.
+		* Então, para autenticar com nossa API, ele manda um header de `Autorização` com o valor `Bearer` mais o token.
+		* Se o token contém `foobar`, o conteúdo do header de `Autorização` será: `Bearer foobar`.
+
+## **FastAPI**'s `OAuth2PasswordBearer`
+
+**FastAPI** fornece várias ferramentas, em diferentes níveis de abstração, para implementar esses recursos de segurança.
+
+Neste exemplo, nós vamos usar o **OAuth2** com o fluxo de **Senha**, usando um token **Bearer**. Fazemos isso usando a classe `OAuth2PasswordBearer`.
+
+!!! informação
+	Um token "bearer" não é a única opção.
+
+	Mas é a melhor no nosso caso.
+
+	E talvez seja a melhor para a maioria dos casos, a não ser que você seja um especialista em OAuth2 e saiba exatamente o porquê de existir outras opções que se adequam melhor às suas necessidades.
+
+	Nesse caso, **FastAPI** também fornece as ferramentas para construir.
+
+Quando nós criamos uma instância da classe `OAuth2PasswordBearer`, nós passamos pelo parâmetro `tokenUrl` Esse parâmetro contém a URL que o client (o frontend rodando no browser do usuário) vai usar para mandar o `username` e `senha` para obter um token.
+
+```Python hl_lines="6"
+{!../../../docs_src/security/tutorial001.py!}
+```
+
+!!! dica
+	Esse `tokenUrl="token"` se refere a uma URL relativa que nós não criamos ainda. Como é uma URL relativa, é equivalente a `./token`.
+
+	Porque estamos usando uma URL relativa, se sua API estava localizada em `https://example.com/`, então irá referir-se à `https://example.com/token`. Mas se sua API estava localizada em `https://example.com/api/v1/`, então irá referir-se à `https://example.com/api/v1/token`.
+
+	Usar uma URL relativa é importante para garantir que sua aplicação continue funcionando, mesmo em um uso avançado tipo [Atrás de um Proxy](../../advanced/behind-a-proxy.md){.internal-link target=_blank}.
+
+Esse parâmetro não cria um endpoint / *path operation*, mas declara que a URL `/token` vai ser aquela que o client deve usar para obter o token. Essa informação é usada no OpenAPI, e depois na API Interativa de documentação de sistemas.
+
+Em breve também criaremos o atual path operation.
+
+!!! informação
+	Se você é um "Pythonista" muito rigoroso, você pode não gostar do estilo do nome do parâmetro `tokenUrl` em vez de `token_url`.
+
+	Isso ocorre porque está utilizando o mesmo nome que está nas especificações do OpenAPI. Então, se você precisa investigar mais sobre qualquer um desses esquemas de segurança, você pode simplesmente copiar e colar para encontrar mais informações sobre isso.
+
+A variável `oauth2_scheme` é um instância de `OAuth2PasswordBearer`, mas também é um "callable".
+
+Pode ser chamada de:
+
+```Python
+oauth2_scheme(some, parameters)
+```
+
+Então, pode ser usado com `Depends`.
+
+## Use-o
+
+Agora você pode passar aquele `oauth2_scheme` em uma dependência com `Depends`.
+
+```Python hl_lines="10"
+{!../../../docs_src/security/tutorial001.py!}
+```
+
+Esse dependência vai fornecer uma `str` que é atribuído ao parâmetro `token da *função do path operation*
+
+A **FastAPI** saberá que pode usar essa dependência para definir um "esquema de segurança" no esquema da OpenAPI (e na documentação da API automática).
+
+!!! informação "Detalhes técnicos"
+	**FastAPI** saberá que pode usar a classe `OAuth2PasswordBearer` (declarada na dependência) para definir o esquema de segurança na OpenAPI porque herda de `fastapi.security.oauth2.OAuth2`, que por sua vez herda de `fastapi.security.base.Securitybase`.
+
+	 Todos os utilitários de segurança que se integram com OpenAPI (e na documentação da API automática) herdam de `SecurityBase`, é assim que **FastAPI** pode saber como integrá-los no OpenAPI.
+
+## O que ele faz
+
+Ele irá e olhará na requisição para aquele header de `Autorização`, verificará se o valor é `Bearer` mais algum token, e vai retornar o token como uma `str`
+
+Se ele não ver o header de `Autorização` ou o valor não tem um token `Bearer`, vai responder com um código de erro  401 (`UNAUTHORIZED`) diretamente.
+
+Você nem precisa verificar se o token existe para retornar um erro. Você pode ter certeza de que se a sua função for executada, ela terá um `str` nesse token.
+
+Você já pode experimentar na documentação interativa:
+
+<img src="/img/tutorial/security/image03.png">
+
+Não estamos verificando a validade do token ainda, mas isso já é um começo
+
+## Recapitulando
+
+Então, em apenas 3 ou 4 linhas extras, você já tem alguma forma primitiva de segurança.

+# О версиях FastAPI
+
+**FastAPI** уже используется в продакшене во многих приложениях и системах. Покрытие тестами поддерживается на уровне 100%. Однако его разработка все еще продолжается.
+
+Часто добавляются новые функции, регулярно исправляются баги, код продолжает постоянно совершенствоваться.
+
+По указанным причинам текущие версии до сих пор `0.x.x`. Это говорит о том, что каждая версия может содержать обратно несовместимые изменения, следуя <a href="https://semver.org/" class="external-link" target="_blank">соглашению о Семантическом Версионировании</a>.
+
+Уже сейчас вы можете создавать приложения в продакшене, используя **FastAPI**  (и скорее всего так и делаете), главное убедиться в том, что вы используете версию, которая корректно работает с вашим кодом.
+
+## Закрепите вашу версию `fastapi`
+
+Первым делом вам следует "закрепить" конкретную последнюю используемую версию **FastAPI**, которая корректно работает с вашим приложением.
+
+Например, в своём приложении вы используете версию `0.45.0`.
+
+Если вы используете файл `requirements.txt`, вы можете указать версию следующим способом:
+
+```txt
+fastapi==0.45.0
+```
+
+это означает, что вы будете использовать именно версию `0.45.0`.
+
+Или вы можете закрепить версию следующим способом:
+
+```txt
+fastapi>=0.45.0,<0.46.0
+```
+
+это значит, что вы используете версии `0.45.0` или выше, но меньше чем `0.46.0`. Например, версия `0.45.2` все еще будет подходить.
+
+Если вы используете любой другой инструмент для управления зависимостями, например Poetry, Pipenv или др., у них у всех имеется способ определения специфической версии для ваших пакетов.
+
+## Доступные версии
+
+Вы можете посмотреть доступные версии (например, проверить последнюю на данный момент) в [примечаниях к выпуску](../release-notes.md){.internal-link target=_blank}.
+
+## О версиях
+
+Следуя соглашению о Семантическом Версионировании, любые версии ниже `1.0.0` потенциально могут добавить обратно несовместимые изменения.
+
+FastAPI следует соглашению в том, что любые изменения "ПАТЧ"-версии предназначены для исправления багов и внесения обратно совместимых изменений.
+
+!!! Подсказка
+    "ПАТЧ" - это последнее число. Например, в `0.2.3`, ПАТЧ-версия - это `3`.
+
+Итак, вы можете закрепить версию следующим образом:
+
+```txt
+fastapi>=0.45.0,<0.46.0
+```
+
+Обратно несовместимые изменения и новые функции добавляются в "МИНОРНЫЕ" версии.
+
+!!! Подсказка
+    "МИНОРНАЯ" версия - это число в середине. Например, в `0.2.3` МИНОРНАЯ версия - это `2`.
+
+## Обновление версий FastAPI
+
+Вам следует добавить тесты для вашего приложения.
+
+С помощью **FastAPI** это очень просто (благодаря Starlette), см. документацию: [Тестирование](../tutorial/testing.md){.internal-link target=_blank}
+
+После создания тестов вы можете обновить свою версию **FastAPI** до более новой. После этого следует убедиться, что ваш код работает корректно, запустив тесты.
+
+Если все работает корректно, или после внесения необходимых изменений все ваши тесты проходят, только тогда вы можете закрепить вашу новую версию `fastapi`.
+
+## О Starlette
+
+Не следует закреплять версию `starlette`.
+
+Разные версии **FastAPI** будут использовать более новые версии Starlette.
+
+Так что решение об используемой версии Starlette, вы можете оставить **FastAPI**.
+
+## О Pydantic
+
+Pydantic включает свои собственные тесты для **FastAPI**, так что новые версии Pydantic (выше `1.0.0`) всегда совместимы с FastAPI.
+
+Вы можете закрепить любую версию Pydantic, которая вам подходит, выше `1.0.0` и ниже `2.0.0`.
+
+Например:
+
+```txt
+pydantic>=1.2.0,<2.0.0
+```

+# Основные свойства
+
+## Основные свойства FastAPI
+
+**FastAPI** предлагает вам следующее:
+
+### Использование открытых стандартов
+
+* <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank"><strong>OpenAPI</strong></a> для создания API, включая объявления <abbr title="также известных, как  HTTP-методы, такие, как: POST, GET, PUT, DELETE">операций</abbr> <abbr title="известные как: эндпоинты, маршруты, 'ручки' и т.п.">пути</abbr>, параметров, тела запроса, безопасности и т.д.
+
+
+* Автоматическое документирование моделей данных в соответствии с <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (так как спецификация OpenAPI сама основана на JSON Schema).
+* Разработан, придерживаясь этих стандартов, после тщательного их изучения. Эти стандарты изначально включены во фреймфорк, а не являются дополнительной надстройкой.
+* Это также позволяет использовать автоматическую **генерацию клиентского кода** на многих языках.
+
+### Автоматически генерируемая документация
+
+Интерактивная документация для API и исследования пользовательских веб-интерфейсов. Поскольку этот фреймворк основан на OpenAPI, существует несколько вариантов документирования, 2 из которых включены по умолчанию.
+
+* <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank"><strong>Swagger UI</strong></a>, с интерактивным взаимодействием, вызывает и тестирует ваш API прямо из браузера.
+
+![Swagger UI interaction](https://fastapi.tiangolo.com/img/index/index-03-swagger-02.png)
+
+* Альтернативная документация API в <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank"><strong>ReDoc</strong></a>.
+
+![ReDoc](https://fastapi.tiangolo.com/img/index/index-06-redoc-02.png)
+
+### Только современный Python
+
+Все эти возможности основаны на стандартных **аннотациях типов Python 3.6** (благодаря Pydantic). Не нужно изучать новый синтаксис. Только лишь стандартный современный Python.
+
+Если вам нужно освежить знания, как использовать аннотации типов в Python (даже если вы не используете FastAPI), выделите 2 минуты и просмотрите краткое руководство: [Введение в аннотации типов Python¶
+](python-types.md){.internal-link target=_blank}.
+
+Вы пишете на стандартном Python с аннотациями типов:
+
+```Python
+from datetime import date
+
+from pydantic import BaseModel
+
+# Объявляем параметр user_id с типом `str`
+# и получаем поддержку редактора внутри функции
+def main(user_id: str):
+    return user_id
+
+
+# Модель Pydantic
+class User(BaseModel):
+    id: int
+    name: str
+    joined: date
+```
+
+Это можно использовать так:
+
+```Python
+my_user: User = User(id=3, name="John Doe", joined="2018-07-19")
+
+second_user_data = {
+    "id": 4,
+    "name": "Mary",
+    "joined": "2018-11-30",
+}
+
+my_second_user: User = User(**second_user_data)
+```
+
+!!! Информация
+    `**second_user_data` означает:
+
+    Передать ключи и значения словаря `second_user_data`,  в качестве аргументов типа "ключ-значение", это эквивалентно: `User(id=4, name="Mary", joined="2018-11-30")` .
+
+### Поддержка редакторов (IDE)
+
+Весь фреймворк был продуман так, чтобы быть простым и интуитивно понятным в использовании, все решения были проверены на множестве редакторов еще до начала разработки, чтобы обеспечить наилучшие условия при написании кода.
+
+В опросе Python-разработчиков было выяснено, <a href="https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features" class="external-link" target="_blank">что наиболее часто используемой функцией редакторов, является "автодополнение"</a>.
+
+Вся структура **FastAPI** основана на удовлетворении этой возможности. Автодополнение работает везде.
+
+Вам редко нужно будет возвращаться к документации.
+
+Вот как ваш редактор может вам помочь:
+
+* в <a href="https://code.visualstudio.com/" class="external-link" target="_blank">Visual Studio Code</a>:
+
+![editor support](https://fastapi.tiangolo.com/img/vscode-completion.png)
+
+* в <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a>:
+
+![editor support](https://fastapi.tiangolo.com/img/pycharm-completion.png)
+
+Вы будете получать автодополнение кода даже там, где вы считали это невозможным раньше.
+Как пример, ключ `price` внутри тела JSON (который может быть вложенным), приходящего в запросе.
+
+Больше никаких неправильных имён ключей, метания по документации или прокручивания кода вверх и вниз, в попытках узнать - использовали вы ранее `username` или `user_name`.
+
+### Краткость
+FastAPI имеет продуманные значения **по умолчанию** для всего, с произвольными настройками везде. Все параметры могут быть тонко подстроены так, чтобы делать то, что вам нужно и определять необходимый вам API.
+
+Но, по умолчанию, всё это **"и так работает"**.
+
+### Проверка значений
+
+* Проверка значений для большинства (или всех?) **типов данных**  Python, включая:
+    * Объекты JSON (`dict`).
+    * Массивы JSON (`list`) с установленными типами элементов.
+    * Строковые (`str`) поля с ограничением минимальной и максимальной длины.
+    * Числа (`int`, `float`) с минимальными и максимальными значениями и т.п.
+
+* Проверка для более экзотических типов, таких как:
+    * URL.
+    * Email.
+    * UUID.
+    * ...и другие.
+
+Все проверки обрабатываются хорошо зарекомендовавшим себя и надежным **Pydantic**.
+
+### Безопасность и аутентификация
+
+Встроеные функции безопасности и аутентификации. Без каких-либо компромиссов с базами данных или моделями данных.
+
+Все схемы безопасности, определённые в OpenAPI, включая:
+
+* HTTP Basic.
+* **OAuth2** (также с **токенами JWT**). Ознакомьтесь с руководством [OAuth2 с JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
+* Ключи API в:
+    * Заголовках.
+    * Параметрах запросов.
+    * Cookies и т.п.
+
+Вдобавок все функции безопасности от Starlette (включая **сессионные cookies**).
+
+Все инструменты и компоненты спроектированы для многократного использования и легко интегрируются с вашими системами, хранилищами данных, реляционными и NoSQL базами данных и т. д.
+
+### Внедрение зависимостей
+
+FastAPI включает в себя чрезвычайно простую в использовании, но чрезвычайно мощную систему <abbr title='известную как: "components", "resources", "services", "providers"'><strong>Внедрения зависимостей</strong></abbr>.
+
+* Даже зависимости могут иметь зависимости, создавая иерархию или **"графы" зависимостей**.
+* Всё **автоматически обрабатывается** фреймворком.
+* Все зависимости могут запрашивать данные из запросов и **дополнять операции пути** ограничениями и автоматической документацией.
+* **Автоматическая проверка** даже для параметров *операций пути*, определенных в зависимостях.
+* Поддержка сложных систем аутентификации пользователей, **соединений с базами данных** и т.д.
+* **Никаких компромиссов** с базами данных, интерфейсами и т.д. Но легкая интеграция со всеми ними.
+
+### Нет ограничений на "Плагины"
+
+Или, другими словами, нет сложностей с ними, импортируйте и используйте нужный вам код.
+
+Любая интеграция разработана настолько простой в использовании (с зависимостями), что вы можете создать "плагин" для своего приложения в пару строк кода, используя ту же структуру и синтаксис, что и для ваших *операций пути*.
+
+### Проверен
+
+* 100% <abbr title="Количество автоматически проверямого кода">покрытие тестами</abbr>.
+* 100% <abbr title="Аннотации типов Python, благодаря которым ваш редактор и другие инструменты могут обеспечить вам лучшую поддержку">аннотирование типов</abbr> в кодовой базе.
+* Используется в реально работающих приложениях.
+
+## Основные свойства Starlette
+
+**FastAPI** основан на <a href="https://www.starlette.io/" class="external-link" target="_blank"><strong>Starlette</strong></a> и полностью совместим с ним. Так что, любой дополнительный код Starlette, который у вас есть, будет также работать.
+
+На самом деле, `FastAPI` - это класс, унаследованный от `Starlette`. Таким образом, если вы уже знаете или используете Starlette, большая часть функционала будет работать так же.
+
+С **FastAPI** вы получаете все возможности **Starlette** (так как FastAPI это всего лишь Starlette на стероидах):
+
+* Серьёзно впечатляющая производительность. Это <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">один из самых быстрых фреймворков на Python</a>, наравне с приложениями использующими **NodeJS** или **Go**.
+* Поддержка **WebSocket**.
+* Фоновые задачи для процессов.
+* События запуска и выключения.
+* Тестовый клиент построен на библиотеке `requests`.
+* **CORS**, GZip, статические файлы, потоковые ответы.
+* Поддержка **сессий и cookie**.
+* 100% покрытие тестами.
+* 100% аннотирование типов в кодовой базе.
+
+## Особенности и возможности Pydantic
+
+**FastAPI** основан на <a href="https://pydantic-docs.helpmanual.io" class="external-link" target="_blank"><strong>Pydantic</strong></a> и полностью совместим с ним. Так что, любой дополнительный код Pydantic, который у вас есть, будет также работать.
+
+Включая внешние библиотеки, также основанные на Pydantic, такие как: <abbr title="Object-Relational Mapper">ORM'ы</abbr>, <abbr title="Object-Document Mapper">ODM'ы</abbr> для баз данных.
+
+Это также означает, что во многих случаях вы можете передавать тот же объект, который получили из запроса, **непосредственно в базу данных**, так как всё проверяется автоматически.
+
+И наоборот, во многих случаях вы можете просто передать объект, полученный из базы данных, **непосредственно клиенту**.
+
+С **FastAPI** вы получаете все возможности **Pydantic** (так как, FastAPI основан на Pydantic, для обработки данных):
+
+* **Никакой нервотрёпки** :
+    * Не нужно изучать новых схем в микроязыках.
+    * Если вы знаете аннотации типов в Python, вы знаете, как использовать Pydantic.
+* Прекрасно сочетается с вашими **<abbr title="Интегрированное окружение для разработки, похожее на текстовый редактор">IDE</abbr>/<abbr title="программа проверяющая ошибки в коде">linter</abbr>/мозгом**:
+    * Потому что структуры данных pydantic - это всего лишь экземпляры классов, определённых вами. Автодополнение, проверка кода, mypy и ваша интуиция - всё будет работать с вашими проверенными данными.
+* **Быстродействие**:
+    * В <a href="https://pydantic-docs.helpmanual.io/benchmarks/" class="external-link" target="_blank">тестовых замерах</a> Pydantic быстрее, чем все другие проверенные библиотеки.
+* Проверка **сложных структур**:
+    * Использование иерархических моделей Pydantic; `List`, `Dict` и т.п. из модуля `typing` (входит в стандартную библиотеку Python).
+    * Валидаторы позволяют четко и легко определять, проверять и документировать сложные схемы данных в виде JSON Schema.
+    * У вас могут быть глубоко **вложенные объекты JSON** и все они будут проверены и аннотированы.
+* **Расширяемость**:
+    * Pydantic позволяет определять пользовательские типы данных или расширять проверку методами модели, с помощью проверочных декораторов.
+* 100% покрытие тестами.

-### Recap
+### Подведём итоги
 
-In summary, you declare **once** the types of parameters, body, etc. as function parameters.
+Таким образом, вы объявляете **один раз** типы параметров, тело и т. д. в качестве параметров функции.
 
-You do that with standard modern Python types.
+Вы делаете это испльзуя стандартную современную типизацию Python.
 
-You don't have to learn a new syntax, the methods or classes of a specific library, etc.
+Вам не нужно изучать новый синтаксис, методы или классы конкретной библиотеки и т. д.
 
-Just standard **Python 3.6+**.
+Только стандартный **Python 3.6+**.
 
-For example, for an `int`:
+Например, для `int`:
 
 ```Python
 item_id: int
 ```
 
-or for a more complex `Item` model:
+или для более сложной модели `Item`:
 
 ```Python
 item: Item
 ```

-Coming back to the previous code example, **FastAPI** will:
+Возвращаясь к предыдущему примеру кода, **FastAPI** будет:
 
-* Validate that there is an `item_id` in the path for `GET` and `PUT` requests.
-* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests.
-    * If it is not, the client will see a useful, clear error.
-* Check if there is an optional query parameter named `q` (as in `http://127.0.0.1:8000/items/foo?q=somequery`) for `GET` requests.
-    * As the `q` parameter is declared with `= None`, it is optional.
-    * Without the `None` it would be required (as is the body in the case with `PUT`).
-* For `PUT` requests to `/items/{item_id}`, Read the body as JSON:
-    * Check that it has a required attribute `name` that should be a `str`.
-    * Check that it has a required attribute `price` that has to be a `float`.
-    * Check that it has an optional attribute `is_offer`, that should be a `bool`, if present.
-    * All this would also work for deeply nested JSON objects.
-* Convert from and to JSON automatically.
-* Document everything with OpenAPI, that can be used by:
-    * Interactive documentation systems.
-    * Automatic client code generation systems, for many languages.
-* Provide 2 interactive documentation web interfaces directly.
+* Проверять наличие `item_id` в пути для запросов `GET` и `PUT`.
+* Проверять, что `item_id` имеет тип `int` для запросов `GET` и `PUT`.
+    * Если это не так, клиент увидит полезную чёткую ошибку.
+* Проверять, есть ли необязательный параметр запроса с именем `q` (например, `http://127.0.0.1:8000/items/foo?q=somequery`) для `GET` запросов.
+    * Поскольку параметр `q` объявлен с `= None`, он является необязательным.
+    * Без `None` он был бы необходим (как тело в случае с `PUT`).
+* Для `PUT` запросов к `/items/{item_id}` читать тело как JSON:
+    * Проверять, что у него есть обязательный атрибут `name`, который должен быть `str`.
+    * Проверять, что у него есть обязательный атрибут `price`, который должен быть `float`.
+    * Проверять, что у него есть необязательный атрибут `is_offer`, который должен быть `bool`, если он присутствует.
+    * Все это также будет работать для глубоко вложенных объектов JSON.
+* Преобразовывать из и в JSON автоматически.
+* Документировать с помощью OpenAPI все, что может быть использовано:
+    * Системы интерактивной документации.
+    * Системы автоматической генерации клиентского кода для многих языков.
+* Обеспечит 2 интерактивных веб-интерфейса документации напрямую.

+# Фоновые задачи
+
+Вы можете создавать фоновые задачи, которые будут выполнятся *после* возвращения ответа сервером.
+
+Это может быть полезно для функций, которые должны выполниться после получения запроса, но ожидание их выполнения необязательно для пользователя.
+
+К примеру:
+
+* Отправка писем на почту после выполнения каких-либо действий:
+    * Т.к. соединение с почтовым сервером и отправка письма идут достаточно "долго" (несколько секунд), вы можете отправить ответ пользователю, а отправку письма выполнить в фоне.
+* Обработка данных:
+    * К примеру, если вы получаете файл, который должен пройти через медленный процесс, вы можете отправить ответ "Accepted" (HTTP 202) и отправить работу с файлом в фон.
+
+## Использование класса `BackgroundTasks`
+
+Сначала импортируйте `BackgroundTasks`, потом добавьте в функцию параметр с типом `BackgroundTasks`:
+
+```Python hl_lines="1  13"
+{!../../../docs_src/background_tasks/tutorial001.py!}
+```
+
+**FastAPI** создаст объект класса `BackgroundTasks` для вас и запишет его в параметр.
+
+## Создание функции для фоновой задачи
+
+Создайте функцию, которую хотите запустить в фоне.
+
+Это совершенно обычная функция, которая может принимать параметры.
+
+Она может быть как асинхронной `async def`, так и обычной `def` функцией, **FastAPI** знает, как правильно ее выполнить.
+
+В нашем примере фоновая задача будет вести запись в файл (симулируя отправку письма).
+
+Так как операция записи не использует `async` и `await`, мы определим ее как обычную `def`:
+
+```Python hl_lines="6-9"
+{!../../../docs_src/background_tasks/tutorial001.py!}
+```
+
+## Добавление фоновой задачи
+
+Внутри функции вызовите метод `.add_task()` у объекта *background tasks* и передайте ему функцию, которую хотите выполнить в фоне:
+
+```Python hl_lines="14"
+{!../../../docs_src/background_tasks/tutorial001.py!}
+```
+
+`.add_task()` принимает следующие аргументы:
+
+* Функцию, которая будет выполнена в фоне (`write_notification`). Обратите внимание, что передается объект функции, без скобок.
+* Любое упорядоченное количество аргументов, которые принимает функция (`email`).
+* Любое количество именованных аргументов, которые принимает функция (`message="some notification"`).
+
+## Встраивание зависимостей
+
+Класс `BackgroundTasks` также работает с системой встраивания зависимостей, вы можете определить `BackgroundTasks` на разных уровнях: как параметр функции, как завимость, как подзависимость и так далее.
+
+**FastAPI** знает, что нужно сделать в каждом случае и как переиспользовать тот же объект `BackgroundTasks`, так чтобы все фоновые задачи собрались и запустились вместе в фоне:
+
+=== "Python 3.6 и выше"
+
+    ```Python hl_lines="13  15  22  25"
+    {!> ../../../docs_src/background_tasks/tutorial002.py!}
+    ```
+
+=== "Python 3.10 и выше"
+
+    ```Python hl_lines="11  13  20  23"
+    {!> ../../../docs_src/background_tasks/tutorial002_py310.py!}
+    ```
+
+В этом примере сообщения будут записаны в `log.txt` *после* того, как ответ сервера был отправлен.
+
+Если бы в запросе была очередь `q`, она бы первой записалась в `log.txt` фоновой задачей (потому что вызывается в зависимости `get_query`).
+
+После другая фоновая задача, которая была сгенерирована в функции, запишет сообщение из параметра `email`.
+
+## Технические детали
+
+Класс `BackgroundTasks` основан на <a href="https://www.starlette.io/background/" class="external-link" target="_blank">`starlette.background`</a>.
+
+Он интегрирован в FastAPI, так что вы можете импортировать его прямо из `fastapi` и избежать случайного импорта `BackgroundTask` (без `s` на конце) из `starlette.background`.
+
+При использовании `BackgroundTasks` (а не `BackgroundTask`), вам достаточно только определить параметр функции с типом `BackgroundTasks` и **FastAPI** сделает все за вас, также как при использовании объекта `Request`.
+
+Вы все равно можете использовать `BackgroundTask` из `starlette` в FastAPI, но вам придется самостоятельно создавать объект фоновой задачи и вручную обработать `Response` внутри него.
+
+Вы можете подробнее изучить его в <a href="https://www.starlette.io/background/" class="external-link" target="_blank">Официальной документации Starlette для BackgroundTasks</a>.
+
+## Предостережение
+
+Если вам нужно выполнить тяжелые вычисления в фоне, которым необязательно быть запущенными в одном процессе с приложением **FastAPI** (к примеру, вам не нужны обрабатываемые переменные или вы не хотите делиться памятью процесса и т.д.), вы можете использовать более серьезные инструменты, такие как <a href="https://docs.celeryproject.org" class="external-link" target="_blank">Celery</a>.
+
+Их тяжелее настраивать, также им нужен брокер сообщений наподобие RabbitMQ или Redis, но зато они позволяют вам запускать фоновые задачи в нескольких процессах и даже на нескольких серверах.
+
+Для примера, посмотрите [Project Generators](../project-generation.md){.internal-link target=_blank}, там есть проект с уже настроенным Celery.
+
+Но если вам нужен доступ к общим переменным и объектам вашего **FastAPI** приложения или вам нужно выполнять простые фоновые задачи (наподобие отправки письма из примера) вы можете просто использовать `BackgroundTasks`.
+
+## Резюме
+
+Для создания фоновых задач вам необходимо импортировать `BackgroundTasks` и добавить его в функцию, как параметр с типом `BackgroundTasks`.
