### `Response`

其他全部的响应都继承自主类 `Response`。

你可以直接返回它。

`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。


```Python hl_lines="1  18"

    @Test
    public void test_Get() {
        Curl.get("https://www.codelibs.org/").execute(response -> {
            final String content = response.getContentAsString();
            logger.info(content);
            assertTrue(content.length() > 0);
        }, e -> {
            logger.log(Level.SEVERE, "error", e);
            fail();
        });
    }

You can return it directly.

It accepts the following parameters:

* `content` - A `str` or `bytes`.
* `status_code` - An `int` HTTP status code.
* `headers` - A `dict` of strings.
* `media_type` - A `str` giving the media type. E.g. `"text/html"`.

FastAPI (actually Starlette) will automatically include a Content-Length header. It will also include a Content-Type header, based on the media_type and appending a charset for text types.
