... wird die Response jetzt Folgendes zurückgeben:

```json

  "message": "Hello World"
}
```

Natürlich werden Sie wahrscheinlich viel bessere Möglichkeiten finden, Vorteil daraus zu ziehen, als JSON zu formatieren. 😉

## Standard-Response-Klasse

Beim Erstellen einer **FastAPI**-Klasseninstanz oder eines `APIRouter`s können Sie angeben, welche Response-Klasse standardmäßig verwendet werden soll.

Esses detalhes são específicos da implementação.

Para OAuth2 são apenas strings.

## Código para conseguir o `username` e a `password`

Agora vamos usar os utilitários fornecidos pelo **FastAPI** para lidar com isso.

### `OAuth2PasswordRequestForm`

Primeiro, importe `OAuth2PasswordRequestForm` e use-o como uma dependência com `Depends` na *operação de rota* para `/token`:
