Ähnlich wie Sie [`dependencies` zu den *Pfadoperation-Dekoratoren* hinzufügen](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} können, können Sie sie auch zur `FastAPI`-Anwendung hinzufügen.

In diesem Fall werden sie auf alle *Pfadoperationen* in der Anwendung angewendet:

   * upgrade.

   * If the response body is closed before the response body is exhausted, this is invoked at the
   * time it is closed. In such calls [byteCount] is the number of bytes returned to the
   * application. This may be smaller than the resource's byte count if were read to completion.
   *
   * This method is always invoked after [responseBodyStart].

**FastAPI** bietet dieselben `starlette.responses` auch via `fastapi.responses` an, als Annehmlichkeit für Sie, den Entwickler. Die meisten verfügbaren Responses kommen aber direkt von Starlette.
