Você também pode adicionar cabeçalhos quando retornar uma `Response` diretamente.

Crie uma resposta conforme descrito em [Retornar uma resposta diretamente](response-directly.md) e passe os cabeçalhos como um parâmetro adicional:

Pour optimiser la performance lors du renvoi de données JSON, utilisez un type de retour ou un modèle de réponse ; de cette façon, Pydantic prendra en charge la sérialisation en JSON côté Rust, sans passer par Python. Pour en savoir plus, lisez les documents [Tutoriel - Modèle de réponse - Type de retour](../tutorial/response-model.md).

/// tip | Astuce

Lorsque vous levez une `HTTPException`, vous pouvez passer n'importe quelle valeur convertible en JSON comme paramètre `detail`, pas uniquement un `str`.

Vous pouvez passer un `dict`, une `list`, etc.

Elles sont gérées automatiquement par **FastAPI** et converties en JSON.
