 *  **OkHttp now does cookies.** We've replaced `java.net.CookieHandler` with
    a new interface, `CookieJar` and added our own `Cookie` model class. This
    new cookie follows the latest RFC and supports the same cookie attributes
    as modern web browsers.

 *  **Form and Multipart bodies are now modeled.** We've replaced the opaque

## 使用 `Response` 参数

你可以在你的*路径操作函数*中声明一个`Response`类型的参数（就像你可以为cookies做的那样）。

然后你可以在这个*临时*响应对象中设置头部。
{* ../../docs_src/response_headers/tutorial002.py hl[1,7:8] *}

然后你可以像平常一样返回任何你需要的对象（例如一个`dict`或者一个数据库模型）。如果你声明了一个`response_model`，它仍然会被用来过滤和转换你返回的对象。

**FastAPI**将使用这个临时响应来提取头部（也包括cookies和状态码），并将它们放入包含你返回的值的最终响应中，该响应由任何`response_model`过滤。

你也可以在依赖项中声明`Response`参数，并在其中设置头部（和cookies）。

## 直接返回 `Response`

你也可以在直接返回`Response`时添加头部。

You can define Header parameters the same way you define `Query`, `Path` and `Cookie` parameters.

## Import `Header` { #import-header }

First import `Header`:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## Declare `Header` parameters { #declare-header-parameters }

Then declare the header parameters using the same structure as with `Path`, `Query` and `Cookie`.
