# Additional Status Codes { #additional-status-codes }

By default, **FastAPI** will return the responses using a `JSONResponse`, putting the content you return from your *path operation* inside of that `JSONResponse`.

It will use the default status code or the one you set in your *path operation*.

## Additional status codes { #additional-status-codes_1 }

Você também pode usar `from starlette.middleware.cors import CORSMiddleware`.

# Codes HTTP supplémentaires

Par défaut, **FastAPI** renverra les réponses à l'aide d'une structure de données `JSONResponse`, en plaçant la réponse de votre  *chemin d'accès* à l'intérieur de cette `JSONResponse`.

Il utilisera le code HTTP par défaut ou celui que vous avez défini dans votre *chemin d'accès*.

También podrías usar `from starlette.middleware.cors import CORSMiddleware`.

この場合、ミドルウェアはリクエストを横取りし、適切なCORSヘッダーと共に情報提供のために `200` または `400` のレスポンスを返します。

### シンプルなリクエスト

`Origin` ヘッダーのあるリクエスト。この場合、ミドルウェアは通常どおりリクエストに何もしないですが、レスポンスに適切なCORSヘッダーを加えます。

/// note

Some response codes (see the next section) indicate that the response does not have a body.

FastAPI knows this, and will produce OpenAPI docs that state there is no response body.
