## カスタム `Response` を返す

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。

```Python hl_lines="1  18"

```

Para produção você usaria `fastapi run` no lugar. 🚀

Internamente, **FastAPI CLI** usa <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>, um servidor ASGI de alta performance e pronto para produção. 😎
