!!! note "Detalles Técnicos"
    `Cookie` es una clase "hermana" de `Path` y `Query`. También hereda de la misma clase común `Param`.

    Pero recuerda que cuando importas `Query`, `Path`, `Cookie`  y otros de `fastapi`, en realidad son funciones que devuelven clases especiales.

!!! info

# Çerez (Cookie) Parametreleri

`Query` (Sorgu) ve `Path` (Yol) parametrelerini tanımladığınız şekilde çerez parametreleri tanımlayabilirsiniz.

## Import `Cookie`

Öncelikle, `Cookie`'yi projenize dahil edin:

=== "Python 3.10+"

    ```Python hl_lines="3"
    {!> ../../../docs_src/cookie_params/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="3"

}

// Cookies implements the Cookies method of the [http.CookieJar] interface.
//
// It returns an empty slice if the URL's scheme is not HTTP or HTTPS.
func (j *Jar) Cookies(u *url.URL) (cookies []*http.Cookie) {
	return j.cookies(u, time.Now())
}

// cookies is like Cookies but takes the current time as a parameter.
func (j *Jar) cookies(u *url.URL, now time.Time) (cookies []*http.Cookie) {

			cookies: []*Cookie{{Name: "Cookie-1", Value: "v$1"}},
		},
		{
			line:    "Cookie-1=v$1;c2=v2",
			cookies: []*Cookie{{Name: "Cookie-1", Value: "v$1"}, {Name: "c2", Value: "v2"}},
		},
		{
			line:    `Cookie-1="v$1";c2="v2"`,
			cookies: []*Cookie{{Name: "Cookie-1", Value: "v$1", Quoted: true}, {Name: "c2", Value: "v2", Quoted: true}},
		},
		{
			line:    "k1=",

	now := tNow

	// Populate jar with cookies.
	setCookies := make([]*http.Cookie, len(test.setCookies))
	for i, cs := range test.setCookies {
		cookies := (&http.Response{Header: http.Header{"Set-Cookie": {cs}}}).Cookies()
		if len(cookies) != 1 {
			panic(fmt.Sprintf("Wrong cookie line %q: %#v", cs, cookies))
		}
		setCookies[i] = cookies[0]
	}
	jar.setCookies(mustParseURL(test.fromURL), setCookies, now)

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.
