Vous pouvez aussi la définir comme une fonction normale au lieu de `async def` :

Você também pode usar `except` para capturar a exceção que foi levantada e fazer algo com ela.

Por exemplo, você pode levantar uma exceção diferente, como `HTTPException`.

O **FastAPI** inclui utilitários para todos esses fluxos de autenticação OAuth2 em `fastapi.security.oauth2`.
