* `www_redirect` - If set to True, requests to non-www versions of the allowed hosts will be redirected to their www counterparts. Defaults to `True`.

If an incoming request does not validate correctly then a `400` response will be sent.

## `GZipMiddleware` { #gzipmiddleware }

Handles GZip responses for any request that includes `"gzip"` in the `Accept-Encoding` header.

The middleware will handle both standard and streaming responses.

9. Diese *Pfadoperation-Funktion* gibt keine Datenklassen zurück (obwohl dies möglich wäre), sondern eine Liste von Dictionarys mit internen Daten.

    FastAPI verwendet den Parameter `response_model` (der Datenklassen enthält), um die Response zu konvertieren.

Sie können `dataclasses` mit anderen Typannotationen auf vielfältige Weise kombinieren, um komplexe Datenstrukturen zu bilden.

Weitere Einzelheiten finden Sie in den Bemerkungen im Quellcode oben.

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>.

Nota que las *path operations* definen los modelos que usan para el payload de la petición y el payload del response, usando los modelos `Item` y `ResponseMessage`.
