The new [ParseCookie] function parses a Cookie header value and
returns all the cookies which were set in it. Since the same cookie
name can appear multiple times the returned Values can contain
more than one value for a given key.

The new [ParseSetCookie] function parses a Set-Cookie header value and

The new [Cookie.Partitioned] field identifies cookies with the Partitioned attribute....

class APIKeyCookie(APIKeyBase):
    """
    API key authentication using a cookie.

    This defines the name of the cookie that should be provided in the request with
    the API key and integrates that into the OpenAPI documentation. It extracts
    the key value sent in the cookie automatically and provides it as the dependency
    result. But it doesn't define how to set that cookie.

    ## Usage

        // cookie
        if (cookieSpec != null) {
            requestConfigBuilder.setCookieSpec(cookieSpec);
        }

        // cookie store
        httpClientBuilder.setDefaultCookieStore(cookieStore);
        if (cookieStore != null) {
            final Cookie[] cookies = getInitParameter(COOKIES_PROPERTY, new Cookie[0], Cookie[].class);
            for (final Cookie cookie : cookies) {

}

// ErrNoCookie is returned by Request's Cookie method when a cookie is not found.
var ErrNoCookie = errors.New("http: named cookie not present")

// Cookie returns the named cookie provided in the request or
// [ErrNoCookie] if not found.
// If multiple cookies match the given name, only one cookie will
// be returned.
func (r *Request) Cookie(name string) (*Cookie, error) {
	if name == "" {
		return nil, ErrNoCookie
	}

		if !found {
			cookiePath = "/"
		}
		// The cookie is using TTL=0, which means they are session cookies (browser is not saving the cookie, expires
		// when the tab is closed). Most pods don't have ability (or code) to actually persist cookies, and expiration
		// is better handled in the cookie content (and consistently in the header value - which doesn't have
		// persistence semantics).

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。
```Python hl_lines="1  7-8"
{!../../../docs_src/response_headers/tutorial002.py!}
```

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`

[Cookie] now preserves double quotes surrounding a cookie value.
The new [Cookie.Quoted] field indicates whether the [Cookie.Value]
