直接返すことができます。

以下のパラメータを受け付けます。

* `content` - `str` か `bytes`。
* `status_code` - `int` のHTTPステータスコード。
* `headers` - 文字列の `dict` 。
* `media_type` - メディアタイプを示す `str` 。例えば `"text/html"` 。

FastAPI (実際にはStarlette) は自動的にContent-Lengthヘッダーを含みます。また、media_typeに基づいたContent-Typeヘッダーを含み、テキストタイプのためにcharsetを追加します。
