## Benutzerdefinierte Header { #custom-headers }

Beachten Sie, dass benutzerdefinierte proprietäre Header <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">mittels des Präfix `X-`</a> hinzugefügt werden können.

## Details zum `Request`-Objekt { #details-about-the-request-object }

Da **FastAPI** unter der Haube eigentlich **Starlette** ist, mit einer Ebene von mehreren Tools darüber, können Sie Starlettes <a href="https://www.starlette.dev/requests/" class="external-link" target="_blank">`Request`</a>-Objekt direkt verwenden, wenn Sie es benötigen.

## Custom Headers { #custom-headers }

Keep in mind that custom proprietary headers can be added <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">using the `X-` prefix</a>.

# Form Verisi

İstek gövdesinde JSON verisi yerine form alanlarını karşılamanız gerketiğinde `Form` sınıfını kullanabilirsiniz.

/// info | Bilgi

Formları kullanmak için öncelikle <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a> paketini indirmeniz gerekmektedir.

Örneğin `pip install python-multipart`.

///

## `Form` Sınıfını Projenize Dahil Edin

/// tip | 提示

确保在每个依赖中只使用一次 `yield`。

///

/// note | 技术细节

任何一个可以与以下内容一起使用的函数：

* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager" class="external-link" target="_blank">`@contextlib.contextmanager`</a> 或者
* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager" class="external-link" target="_blank">`@contextlib.asynccontextmanager`</a>

* `datetime.timedelta`:
    * Ein Python-`datetime.timedelta`.
    * Wird in Requests und Responses als `float` der Gesamtsekunden dargestellt.
    * Pydantic ermöglicht auch die Darstellung als „ISO 8601 Zeitdifferenz-Kodierung“, <a href="https://docs.pydantic.dev/latest/concepts/serialization/#custom-serializers" class="external-link" target="_blank">siehe die Dokumentation für weitere Informationen</a>.
* `frozenset`:

この行はローカルマシンでアプリが提供されているURLを示しています。

### チェック

ブラウザで<a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>を開きます。

次のようなJSONレスポンスが表示されます:

```JSON
{"message": "Hello World"}
```

### 対話的APIドキュメント

次に、<a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>にアクセスします。

Starlette (y **FastAPI**) están basados en <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, lo que lo hace compatible tanto con el <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> del paquete estándar de Python como con <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>.

And then another background task generated at the *path operation function* will write a message using the `email` path parameter.

## Technical Details { #technical-details }

The class `BackgroundTasks` comes directly from <a href="https://www.starlette.dev/background/" class="external-link" target="_blank">`starlette.background`</a>.
