主要的 `Response` 類別，其他回應皆繼承自它。

你也可以直接回傳它。

它接受以下參數：

- `content` - `str` 或 `bytes`。
- `status_code` - `int` 類型的 HTTP 狀態碼。
- `headers` - 由字串組成的 `dict`。
- `media_type` - 描述 media type 的 `str`。例如 `"text/html"`。

FastAPI（實際上是 Starlette）會自動包含 Content-Length 標頭。也會根據 `media_type`（並為文字型別附加 charset）包含 Content-Type 標頭。
