上記の例では必要な部分を全て示していますが、あまり便利ではありません。`item` を直接返すことができるし、**FastAPI** はそれを `dict` に変換して `JSONResponse`　に含めてくれるなど。すべて、デフォルトの動作です。

では、これを使ってカスタムレスポンスをどう返すか見てみましょう。

<a href="https://en.wikipedia.org/wiki/XML" class="external-link" target="_blank">XML</a>レスポンスを返したいとしましょう。

XMLを文字列にし、`Response` に含め、それを返します。

## 備考

`Response` を直接返す場合、バリデーションや、変換 (シリアライズ) や、自動ドキュメントは行われません。

### Response Elements

XML response for this API is similar to [AWS STS AssumeRole](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html#API_AssumeRole_ResponseElements)
