En utilisant seulement `BackgroundTasks` (et non `BackgroundTask`), il est possible de l'utiliser en tant que paramètre de *fonction de chemin* et de laisser **FastAPI** gérer le reste pour vous, comme en utilisant l'objet `Request` directement.

Il est tout de même possible d'utiliser `BackgroundTask` seul dans **FastAPI**, mais dans ce cas il faut créer l'objet dans le code et renvoyer une `Response` Starlette l'incluant.

## Abhängigkeitsfehler und -Rückgabewerte

Sie können dieselben Abhängigkeits-*Funktionen* verwenden, die Sie normalerweise verwenden.

### Abhängigkeitsanforderungen

Sie können Anforderungen für einen Request (wie Header) oder andere Unterabhängigkeiten deklarieren:
