For example, let's say that you want to have a *path operation* that allows to update items, and returns HTTP status codes of 200 "OK" when successful.

But you also want it to accept new items. And when the items didn't exist before, it creates them, and returns an HTTP status code of 201 "Created".

To achieve that, import `JSONResponse`, and return your content there directly, setting the `status_code` that you want:

## Documentação interativa da API

Agora você pode ir para <a href="http://192.168.99.100/docs" class="external-link" target="_blank">http://192.168.99.100/docs</a> ou <a href="http://127.0.0.1/docs" class="external-link" target="_blank">http://127.0.0.1/docs</a> (ou equivalente, usando seu host Docker).

例えば、パフォーマンスを出したい場合は、<a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>をインストールし、`ORJSONResponse`をレスポンスとしてセットすることができます。

使いたい `Response` クラス (サブクラス) をインポートし、 *path operationデコレータ* に宣言します。

{* ../../docs_src/custom_response/tutorial001b.py hl[2,7] *}

/// info | 情報

パラメータ `response_class` は、レスポンスの「メディアタイプ」を定義するために利用することもできます。

この場合、HTTPヘッダー `Content-Type` には `application/json` がセットされます。
