Vous avez vu que vous pouvez utiliser des dépendances avec `yield` et avoir des blocs `try` qui tentent d'exécuter du code puis exécutent du code de sortie après `finally`.

Vous pouvez également utiliser `except` pour intercepter l'exception qui a été levée et faire quelque chose avec.

Par exemple, vous pouvez lever une autre exception, comme `HTTPException`.

### Requisições CORS pré-voo (preflight) { #cors-preflight-requests }

Estas são quaisquer solicitações `OPTIONS` com cabeçalhos `Origin` e `Access-Control-Request-Method`.

Nesse caso, o middleware interceptará a solicitação recebida e responderá com cabeçalhos CORS apropriados e uma resposta `200` ou `400` para fins informativos.
