而且你还可以根据你的需要响应不同的对象，比如常用的 `dict`，数据库model等。

如果你定义了 `response_model`，程序会自动根据`response_model`来过滤和转换你响应的对象。

**FastAPI** 会使用这个 *临时* 响应对象去装在这些cookies信息 (同样还有headers和状态码等信息), 最终会将这些信息和通过`response_model`转化过的数据合并到最终的响应里。

你也可以在依赖中定义`Response`参数，并设置cookie和header。

## 直接响应 `Response` { #return-a-response-directly }

你还可以在直接响应`Response`时直接创建cookies。

为此，你可以按照[直接返回 Response](response-directly.md)中的说明创建一个响应。

然后设置Cookies，并返回：
