Es ist immer noch möglich, `BackgroundTask` allein in FastAPI zu verwenden, aber Sie müssen das Objekt in Ihrem Code erstellen und eine Starlette-`Response` zurückgeben, die es enthält.

Weitere Details finden Sie in [Starlettes offizieller Dokumentation für Hintergrundtasks](https://www.starlette.dev/background/).
