しかし場合によっては、デフォルトとは異なるステータスコードを返す必要があります。

## ユースケース { #use-case }

たとえば、デフォルトでは HTTP ステータスコード "OK" `200` を返したいとします。

しかし、データが存在しなければそれを作成し、HTTP ステータスコード "CREATED" `201` を返したい。

それでも、返すデータは `response_model` でフィルタ・変換できるようにしておきたい。

そのような場合は `Response` パラメータを使えます。

## `Response` パラメータを使う { #use-a-response-parameter }

*path operation* 関数で `Response` 型のパラメータを宣言できます（Cookie やヘッダーと同様です）。

## Сценарии использования { #use-cases }

Некоторые сценарии:

* Преобразование тел запросов, не в формате JSON, в JSON (например, [`msgpack`](https://msgpack.org/index.html)).
* Распаковка тел запросов, сжатых с помощью gzip.
