`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 desde `fastapi`, en realidad son funciones que devuelven clases especiales.

///

/// info | Información

Para declarar cookies, necesitas usar `Cookie`, porque de lo contrario los parámetros serían interpretados como parámetros de query.

///

/// info | Información

`Cookie` is a "sister" class of `Path` and `Query`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Cookie` and others from `fastapi`, those are actually functions that return special classes.

///

/// info

To declare cookies, you need to use `Cookie`, because otherwise the parameters would be interpreted as query parameters.

Ви можете визначити параметри Cookie таким же чином, як визначаються параметри `Query` і `Path`.

## Імпорт `Cookie`

Спочатку імпортуйте `Cookie`:

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

## Визначення параметрів `Cookie`

Потім визначте параметри cookie, використовуючи таку ж конструкцію як для `Path` і `Query`.

 定义 `Cookie` 参数与定义 `Query` 和 `Path` 参数一样。

## 导入 `Cookie`

首先，导入 `Cookie`：

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

## 声明 `Cookie` 参数

声明 `Cookie` 参数的方式与声明 `Query` 和 `Path` 参数相同。

第一个值是默认值，还可以传递所有验证参数或注释参数：


{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[9] *}

/// note | 技术细节

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