Par défaut, **FastAPI** convertirait automatiquement cette valeur de retour en JSON en utilisant le `jsonable_encoder` expliqué dans [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

Ensuite, en arrière-plan, il mettra ces données JSON-compatible (par exemple un `dict`) à l'intérieur d'un `JSONResponse` qui sera utilisé pour envoyer la réponse au client.

## Пример

В качестве простого примера, давайте рассмотрим файловую структуру, схожую с описанной в [Большие приложения](../tutorial/bigger-applications.md){.internal-link target=_blank} и [Тестирование](../tutorial/testing.md){.internal-link target=_blank}:

```

## Eine `Response` direkt zurückgeben

Sie können auch Header hinzufügen, wenn Sie eine `Response` direkt zurückgeben.

Erstellen Sie eine Response wie in [Eine Response direkt zurückgeben](response-directly.md){.internal-link target=_blank} beschrieben und übergeben Sie die Header als zusätzlichen Parameter:
