/// tip | Astuce

Vous aurez normalement une bien meilleure performance en utilisant un [Modèle de réponse](../tutorial/response-model.md) qu'en renvoyant directement une `JSONResponse`, car de cette façon la sérialisation des données est effectuée par Pydantic, en Rust.

///

## Renvoyer une `Response` { #return-a-response }

Vous pouvez renvoyer une `Response` ou n'importe laquelle de ses sous-classes.

/// info

Ancak çoğu durumda bir dosyayı veya dosya benzeri bir nesneyi okumak bloke edicidir.

///

Event loop'u bloke etmemek için, *path operation function*'ı `async def` yerine normal `def` ile tanımlayabilirsiniz; böylece FastAPI ana döngüyü bloke etmemek için bunu bir thread pool worker (iş parçacığı havuzu çalışanı) üzerinde çalıştırır.

    The actual encoding logic lives in the FastAPI routing layer. This class
    serves mainly as a marker and sets the correct `Content-Type`.

7. ここでは `response_model` に `Author` dataclass のリストという型注釈を使用しています。

    このように、`dataclasses` は標準の型注釈と組み合わせられます。

8. この *path operation 関数* は、`async def` ではなく通常の `def` を使用しています。

    いつもどおり、FastAPI では必要に応じて `def` と `async def` を組み合わせられます。

    どちらをいつ使うかの復習が必要な場合は、[`async` と `await`](../async.md#in-a-hurry) に関するドキュメントの _"In a hurry?"_ セクションを参照してください。
