# 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"

    {!> ../../../docs_src/cookie_params/tutorial001.py!}
    ```

!!! note "技术细节"

    `Cookie` 、`Path` 、`Query` 是**兄弟类**，都继承自共用的 `Param` 类。

    注意，从 `fastapi` 导入的 `Query`、`Path`、`Cookie` 等对象，实际上是返回特殊类的函数。

!!! info "说明"

    必须使用 `Cookie` 声明 cookie 参数，否则该参数会被解释为查询参数。

// Transports are safe for concurrent use by multiple goroutines.
//
// A Transport is a low-level primitive for making HTTP and HTTPS requests.
// For high-level functionality, such as cookies and redirects, see [Client].
//
// Transport uses HTTP/1.1 for HTTP URLs and either HTTP/1.1 or HTTP/2
// for HTTPS URLs, depending on whether the server supports HTTP/2,

        Set<String> roleSet;
        Cookie cookie;

        roleSet = buildByCookie(roleQueryHelperImpl, getMockRequest());
        assertEquals(0, roleSet.size());

        cookie = new Cookie("aaa", "bbb");
        getMockRequest().addCookie(cookie);

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

It includes:

* `Query()`
* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

You can import them all directly from `fastapi`:

```python
from fastapi import Body, Cookie, File, Form, Header, Path, Query
```

::: fastapi.Query

::: fastapi.Path

::: fastapi.Body

::: fastapi.Cookie

::: fastapi.Header

::: fastapi.Form

Dies beinhaltet:

* `Query()`
* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

Sie können diese alle direkt von `fastapi` importieren:

```python
from fastapi import Body, Cookie, File, Form, Header, Path, Query
```

::: fastapi.Query

::: fastapi.Path

::: fastapi.Body

::: fastapi.Cookie

::: fastapi.Header

::: fastapi.Form
