* It takes each **request** that comes to your application.
* It can then do something to that **request** or run any needed code.
* Then it passes the **request** to be processed by the rest of the application (by some *path operation*).

你可以用與定義 `Query` 與 `Path` 參數相同的方式定義 Cookie 參數。

## 匯入 `Cookie` { #import-cookie }

先匯入 `Cookie`：

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

## 宣告 `Cookie` 參數 { #declare-cookie-parameters }

然後用與 `Path`、`Query` 相同的結構宣告 `Cookie` 參數。

你可以設定預設值，以及所有額外的驗證或註解參數：

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