`Response` 类接受如下参数：

* `content` - 一个 `str` 或者 `bytes`。
* `status_code` - 一个 `int` 类型的 HTTP 状态码。
* `headers` - 一个由字符串组成的 `dict`。
* `media_type` - 一个给出媒体类型的 `str`，比如 `"text/html"`。

FastAPI（实际上是 Starlette）将自动包含 Content-Length 的头。它还将包含一个基于 `media_type` 的 Content-Type 头，并为文本类型附加一个字符集。

### `HTMLResponse` { #htmlresponse }

如上文所述，接受文本或字节并返回 HTML 响应。
