# Response-Header

## Verwenden Sie einen `Response`-Parameter

Sie können einen Parameter vom Typ `Response` in Ihrer *Pfadoperation-Funktion* deklarieren (wie Sie es auch für Cookies tun können).

Und dann können Sie Header in diesem *vorübergehenden* Response-Objekt festlegen.

{* ../../docs_src/response_headers/tutorial002.py hl[1,7:8] *}

Anschließend können Sie wie gewohnt jedes gewünschte Objekt zurückgeben (ein `dict`, ein Datenbankmodell, usw.).

## Über Starlette

Sie sollten die Version von `starlette` nicht pinnen.

Verschiedene Versionen von **FastAPI** verwenden eine bestimmte neuere Version von Starlette.

Sie können **FastAPI** also einfach die korrekte Starlette-Version verwenden lassen.
