Wenn Sie einen anderen Anwendungsfall haben, der ein frühes Beenden aus einer Abhängigkeit mit `yield` benötigt, erstellen Sie bitte eine <a href="https://github.com/fastapi/fastapi/discussions/new?category=questions" class="external-link" target="_blank">GitHub-Diskussion-Frage</a> mit Ihrem spezifischen Anwendungsfall und warum Sie von einem frühen Schließen für Abhängigkeiten mit `yield` profitieren würden.

Wenn Sie eine ältere Version haben, werden Sie Fehler angezeigt bekommen, wenn Sie versuchen, `Annotated` zu verwenden.

Bitte [aktualisieren Sie FastAPI](../../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} daher mindestens zu Version 0.95.1, bevor Sie `Annotated` verwenden.

Alternativ kann `status_code` auch ein `IntEnum` erhalten, wie etwa Pythons <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>.

Dies wird:

В качестве значения параметра `status_code` также может использоваться `IntEnum`, например, из библиотеки <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a> в Python.
