 Now, you should be able to disconnect your WiFi, go to your docs at <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>, and reload the page.

 And even without Internet, you would be able to see the docs for your API and interact with it.
+
+## Configuring Swagger UI
+
+You can configure some extra <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration" class="external-link" target="_blank">Swagger UI parameters</a>.
+
+To configure them, pass the `swagger_ui_parameters` argument when creating the `FastAPI()` app object or to the `get_swagger_ui_html()` function.
+
+`swagger_ui_parameters` receives a dictionary with the configurations passed to Swagger UI directly.
+
+FastAPI converts the configurations to **JSON** to make them compatible with JavaScript, as that's what Swagger UI needs.
+
+### Disable Syntax Highlighting
+
+For example, you could disable syntax highlighting in Swagger UI.
+
+Without changing the settings, syntax highlighting is enabled by default:
+
+<img src="/img/tutorial/extending-openapi/image02.png">
+
+But you can disable it by setting `syntaxHighlight` to `False`:
+
+```Python hl_lines="3"
+{!../../../docs_src/extending_openapi/tutorial003.py!}
+```
+
+...and then Swagger UI won't show the syntax highlighting anymore:
+
+<img src="/img/tutorial/extending-openapi/image03.png">
+
+### Change the Theme
+
+The same way you could set the syntax highlighting theme with the key `"syntaxHighlight.theme"` (notice that it has a dot in the middle):
+
+```Python hl_lines="3"
+{!../../../docs_src/extending_openapi/tutorial004.py!}
+```
+
+That configuration would change the syntax highlighting color theme:
+
+<img src="/img/tutorial/extending-openapi/image04.png">
+
+### Change Default Swagger UI Parameters
+
+FastAPI includes some default configuration parameters appropriate for most of the use cases.
+
+It includes these default configurations:
+
+```Python
+{!../../../fastapi/openapi/docs.py[ln:7-13]!}
+```
+
+You can override any of them by setting a different value in the argument `swagger_ui_parameters`.
+
+For example, to disable `deepLinking` you could pass these settings to `swagger_ui_parameters`:
+
+```Python hl_lines="3"
+{!../../../docs_src/extending_openapi/tutorial005.py!}
+```
+
+### Other Swagger UI Parameters
+
+To see all the other possible configurations you can use, read the official <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration" class="external-link" target="_blank">docs for Swagger UI parameters</a>.
+
+### JavaScript-only settings
+
+Swagger UI also allows other configurations to be **JavaScript-only** objects (for example, JavaScript functions).
+
+FastAPI also includes these JavaScript-only `presets` settings:
+
+```JavaScript
+presets: [
+    SwaggerUIBundle.presets.apis,
+    SwaggerUIBundle.SwaggerUIStandalonePreset
+]
+```
+
+These are **JavaScript** objects, not strings, so you can't pass them from Python code directly.
+
+If you need to use JavaScript-only configurations like those, you can use one of the methods above. Override all the Swagger UI *path operation* and manually write any JavaScript you need.

 ## Latest Changes

+
+## 0.74.1
+
+### Features
+
+* ✨ Include route in scope to allow middleware and other tools to extract its information. PR [#4603](https://github.com/tiangolo/fastapi/pull/4603) by [@tiangolo](https://github.com/tiangolo).
+
+## 0.74.0
+
+### Breaking Changes
+
+* ✨ Update internal `AsyncExitStack` to fix context for dependencies with `yield`. PR [#4575](https://github.com/tiangolo/fastapi/pull/4575) by [@tiangolo](https://github.com/tiangolo).
+
+Dependencies with `yield` can now catch `HTTPException` and custom exceptions. For example:
+
+```Python
+async def get_database():
+    with Session() as session:
+        try:
+            yield session
+        except HTTPException:
+            session.rollback()
+            raise
+        finally:
+            session.close()
+```
+
+After the dependency with `yield` handles the exception (or not) the exception is raised again. So that any exception handlers can catch it, or ultimately the default internal `ServerErrorMiddleware`.
+
+If you depended on exceptions not being received by dependencies with `yield`, and receiving an exception breaks the code after `yield`, you can use a block with `try` and `finally`:
+
+```Python
+async def do_something():
+    try:
+        yield something
+    finally:
+        some_cleanup()
+```
+
+...that way the `finally` block is run regardless of any exception that might happen.
+
+### Features
+
+* The same PR [#4575](https://github.com/tiangolo/fastapi/pull/4575) from above also fixes the `contextvars` context for the code before and after `yield`. This was the main objective of that PR.
+
+This means that now, if you set a value in a context variable before `yield`, the value would still be available after `yield` (as you would intuitively expect). And it also means that you can reset the context variable with a token afterwards.
+
+For example, this works correctly now:
+
+```Python
+from contextvars import ContextVar
+from typing import Any, Dict, Optional
+
+
+legacy_request_state_context_var: ContextVar[Optional[Dict[str, Any]]] = ContextVar(
+    "legacy_request_state_context_var", default=None
+)
+
+async def set_up_request_state_dependency():
+    request_state = {"user": "deadpond"}
+    contextvar_token = legacy_request_state_context_var.set(request_state)
+    yield request_state
+    legacy_request_state_context_var.reset(contextvar_token)
+```
+
+...before this change it would raise an error when resetting the context variable, because the `contextvars` context was different, because of the way it was implemented.
+
+**Note**: You probably don't need `contextvars`, and you should probably avoid using them. But they are powerful and useful in some advanced scenarios, for example, migrating from code that used Flask's `g` semi-global variable.
+
+**Technical Details**: If you want to know more of the technical details you can check out the PR description [#4575](https://github.com/tiangolo/fastapi/pull/4575).

-In summary, you declare **once** the types of parameters, body, etc. as function parameters. 
+Podsumowując, musiałeś zadeklarować typy parametrów, treści żądania (body) itp. tylko **raz**, i są one dostępne jako parametry funkcji.

-You do that with standard modern Python types.
+Robisz to tak samo jak ze standardowymi typami w Pythonie.

-You don't have to learn a new syntax, the methods or classes of a specific library, etc.
+Nie musisz sie uczyć żadnej nowej składni, metod lub klas ze specyficznych bibliotek itp.

-Just standard **Python 3.6+**.
+Po prostu standardowy **Python 3.6+**.

+Na przykład, dla danych typu `int`:

 item_id: int

-Coming back to the previous code example, **FastAPI** will:
+Wracając do poprzedniego przykładu, **FastAPI** :

-* 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.
+* Potwierdzi, że w ścieżce jest `item_id` dla żądań `GET` i `PUT`.
+* Potwierdzi, że `item_id` jest typu `int` dla żądań `GET` i `PUT`.
+    * Jeżeli nie jest, odbiorca zobaczy przydatną, przejrzystą wiadomość z błędem.
+* Sprawdzi czy w ścieżce jest opcjonalny parametr zapytania `q` (np. `http://127.0.0.1:8000/items/foo?q=somequery`) dla żądania `GET`.
+    * Jako że parametr `q` jest zadeklarowany jako `= None`, jest on opcjonalny.
+    * Gdyby tego `None` nie było, parametr ten byłby wymagany (tak jak treść żądania w żądaniu `PUT`).
+* Dla żądania `PUT` z ścieżką `/items/{item_id}`, odczyta treść żądania jako JSON:
+    * Sprawdzi czy posiada wymagany atrybut `name`, który powinien być typu `str`.
+    * Sprawdzi czy posiada wymagany atrybut `price`, który musi być typu `float`.
+    * Sprawdzi czy posiada opcjonalny atrybut `is_offer`, który (jeżeli obecny) powinien być typu `bool`.
+    * To wszystko będzie również działać dla głęboko zagnieżdżonych obiektów JSON.
+* Automatycznie konwertuje z i do JSON.
+* Dokumentuje wszystko w OpenAPI, które może być używane przez:
+    * Interaktywne systemy dokumentacji.
+    * Systemy automatycznego generowania kodu klienckiego, dla wielu języków.
+* Dostarczy bezpośrednio 2 interaktywne dokumentacje webowe.

+To dopiero początek, ale już masz mniej-więcej pojęcie jak to wszystko działa.

-Try changing the line with:

+Dla bardziej kompletnych przykładów posiadających więcej funkcjonalności, zobacz <a href="https://fastapi.tiangolo.com/tutorial/">Tutorial - User Guide</a>.

-**Spoiler alert**: the tutorial - user guide includes:
+**Uwaga Spoiler**: tutorial - user guide zawiera:

-* Declaration of **parameters** from other different places as: **headers**, **cookies**, **form fields** and **files**.
-* How to set **validation constraints** as `maximum_length` or `regex`.
-* A very powerful and easy to use **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system.
-* Security and authentication, including support for **OAuth2** with **JWT tokens** and **HTTP Basic** auth.
-* More advanced (but equally easy) techniques for declaring **deeply nested JSON models** (thanks to Pydantic).
-* Many extra features (thanks to Starlette) as:
-    * **WebSockets**
+* Deklaracje **parametrów** z innych miejsc takich jak: **nagłówki**, **pliki cookies**, **formularze** i **pliki**.
+* Jak ustawić **ograniczenia walidacyjne** takie jak `maksymalna długość` lub `regex`.
+* Potężny i łatwy w użyciu system **<abbr title="znane jako komponenty, resources, providers, services, injectables">Dependency Injection</abbr>**.
+* Zabezpieczenia i autentykacja, wliczając wsparcie dla **OAuth2** z **tokenami JWT** oraz autoryzacją **HTTP Basic**.
+* Bardziej zaawansowane (ale równie proste) techniki deklarowania **głęboko zagnieżdżonych modeli JSON** (dzięki Pydantic).
+* Wiele dodatkowych funkcji (dzięki Starlette) takie jak:
+    * **WebSockety**
    * **GraphQL**
-    * extremely easy tests based on `requests` and `pytest`
+    * bardzo proste testy bazujące na `requests` oraz `pytest`
    * **CORS**
-    * **Cookie Sessions**
-    * ...and more.

-Independent TechEmpower benchmarks show **FastAPI** applications running under Uvicorn as <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">one of the fastest Python frameworks available</a>, only below Starlette and Uvicorn themselves (used internally by FastAPI). (*)
+Niezależne benchmarki TechEmpower pokazują, że **FastAPI** (uruchomiony na serwerze Uvicorn) <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">jest jednym z najszybszych dostępnych Pythonowych frameworków</a>, zaraz po Starlette i Uvicorn (używanymi wewnątrznie przez FastAPI).

+## 加入聊天
+
+快加入 👥 <a href="https://discord.gg/VQjSZaeJmf" class="external-link" target="_blank">Discord 聊天服务器</a> 👥 和 FastAPI 社区里的小伙伴一起哈皮吧。
+
+!!! tip "提示"
+
+    如有问题，请在 <a href="https://github.com/tiangolo/fastapi/issues/new/choose" class="external-link" target="_blank">GitHub Issues</a> 里提问，在这里更容易得到 [FastAPI 专家](fastapi-people.md#experts){.internal-link target=_blank}的帮助。
+    
+    聊天室仅供闲聊。
+
+我们之前还使用过 <a href="https://gitter.im/tiangolo/fastapi" class="external-link" target="_blank">Gitter chat</a>，但它不支持频道等高级功能，聊天也比较麻烦，所以现在推荐使用 Discord。
+
+### 别在聊天室里提问
+
+注意，聊天室更倾向于“闲聊”，经常有人会提出一些笼统得让人难以回答的问题，所以在这里提问一般没人回答。
+
+GitHub Issues 里提供了模板，指引您提出正确的问题，有利于获得优质的回答，甚至可能解决您还没有想到的问题。而且就算答疑解惑要耗费不少时间，我还是会尽量在 GitHub 里回答问题。但在聊天室里，我就没功夫这么做了。😅
+
+聊天室里的聊天内容也不如 GitHub 里好搜索，聊天里的问答很容易就找不到了。只有在 GitHub Issues 里的问答才能帮助您成为  [FastAPI 专家](fastapi-people.md#experts){.internal-link target=_blank}，在 GitHub Issues 中为您带来更多关注。
+
+另一方面，聊天室里有成千上万的用户，在这里，您有很大可能遇到聊得来的人。😄

+# 路径操作配置
+
+*路径操作装饰器*支持多种配置参数。
+
+!!! warning "警告"
+
+    注意：以下参数应直接传递给**路径操作装饰器**，不能传递给*路径操作函数*。
+
+## `status_code` 状态码
+
+`status_code` 用于定义*路径操作*响应中的 HTTP 状态码。
+
+可以直接传递 `int` 代码， 比如 `404`。
+
+如果记不住数字码的涵义，也可以用 `status` 的快捷常量：
+
+```Python hl_lines="3  17"
+{!../../../docs_src/path_operation_configuration/tutorial001.py!}
+```
+
+状态码在响应中使用，并会被添加到 OpenAPI 概图。
+
+!!! note "技术细节"
+
+    也可以使用 `from starlette import status` 导入状态码。
+    
+    **FastAPI** 的`fastapi.status` 和 `starlette.status` 一样，只是快捷方式。实际上，`fastapi.status` 直接继承自 Starlette。
+
+## `tags` 参数
+
+`tags` 参数的值是由 `str` 组成的 `list` （一般只有一个 `str` ），`tags` 用于为*路径操作*添加标签：
+
+```Python hl_lines="17  22  27"
+{!../../../docs_src/path_operation_configuration/tutorial002.py!}
+```
+
+OpenAPI 概图会自动添加标签，供 API 文档接口使用：
+
+<img src="/img/tutorial/path-operation-configuration/image01.png">
+
+## `summary` 和 `description` 参数
+
+路径装饰器还支持 `summary` 和 `description` 这两个参数：
+
+```Python hl_lines="20-21"
+{!../../../docs_src/path_operation_configuration/tutorial003.py!}
+```
+
+## 文档字符串（`docstring`）
+
+描述内容比较长且占用多行时，可以在函数的 <abbr title="函数中作为第一个表达式，用于文档目的的一个多行字符串（并没有被分配个任何变量）">docstring</abbr> 中声明*路径操作*的描述，**FastAPI** 支持从文档字符串中读取描述内容。
+
+文档字符串支持 <a href="https://en.wikipedia.org/wiki/Markdown" class="external-link" target="_blank">Markdown</a>，能正确解析和显示 Markdown 的内容，但要注意文档字符串的缩进。
+
+```Python hl_lines="19-27"
+{!../../../docs_src/path_operation_configuration/tutorial004.py!}
+```
+
+下图为 Markdown 文本在 API 文档中的显示效果：
+
+<img src="/img/tutorial/path-operation-configuration/image02.png">
+
+## 响应描述
+
+`response_description` 参数用于定义响应的描述说明：
+
+```Python hl_lines="21"
+{!../../../docs_src/path_operation_configuration/tutorial005.py!}
+```
+
+!!! info "说明"
+
+    注意，`response_description` 只用于描述响应，`description` 一般则用于描述*路径操作*。
+
+!!! check "检查"
+
+    OpenAPI 规定每个*路径操作*都要有响应描述。
+    
+    如果没有定义响应描述，**FastAPI** 则自动生成内容为 "Successful response" 的响应描述。
+
+<img src="/img/tutorial/path-operation-configuration/image03.png">
+
+## 弃用*路径操作*
+
+`deprecated` 参数可以把*路径操作*标记为<abbr title="过时，建议不要使用">弃用</abbr>，无需直接删除：
