### `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。

            "input": "plumbus"
        }
    ]
}
```

## 总结

你可以使用 **Pydantic 模型**在 **FastAPI** 中声明**查询参数**。😎

/// tip

剧透警告：你也可以使用 Pydantic 模型来声明 cookie 和 headers，但你将在本教程的后面部分阅读到这部分内容。🤫
