Stellen Sie sich zum Beispiel vor, Sie möchten standardmäßig den HTTP-Statuscode „OK“ `200` zurückgeben.

Wenn die Daten jedoch nicht vorhanden sind, möchten Sie diese erstellen und den HTTP-Statuscode „CREATED“ `201` zurückgeben.

Sie möchten aber dennoch in der Lage sein, die von Ihnen zurückgegebenen Daten mit einem `response_model` zu filtern und zu konvertieren.

In diesen Fällen können Sie einen `Response`-Parameter verwenden.
