## Cookie з Pydantic-моделлю

Оголосіть **cookie-параметри**, які Вам потрібні, у **Pydantic-моделі**, а потім оголосіть параметр як `Cookie`:

{* ../../docs_src/cookie_param_models/tutorial001_an_py310.py hl[9:12,16] *}

**FastAPI** буде **витягувати** дані для **кожного поля** з **cookie** параметрів, отриманих у запиті, і передавати Вам Pydantic-модель, яку Ви визначили.

创建设置令牌过期时间的变量。

定义令牌端点响应的 Pydantic 模型。

创建生成新的访问令牌的工具函数。

{* ../../docs_src/security/tutorial004.py hl[6,12:14,28:30,78:86] *}

## 更新依赖项

更新 `get_current_user` 以接收与之前相同的令牌，但这里用的是 JWT 令牌。

解码并校验接收到的令牌，然后，返回当前用户。

如果令牌无效，则直接返回 HTTP 错误。

{* ../../docs_src/security/tutorial004_an_py310.py hl[4,7,13:15,29:31,79:87] *}

## 更新 `/token` *路径操作*

用令牌过期时间创建 `timedelta` 对象。

## `Form`のインポート

`fastapi`から`Form`をインポートします:

{* ../../docs_src/request_forms/tutorial001.py hl[1] *}

## `Form`のパラメータの定義

`Body`や`Query`の場合と同じようにフォームパラメータを作成します:

{* ../../docs_src/request_forms/tutorial001.py hl[7] *}

例えば、OAuth2仕様が使用できる方法の１つ（「パスワードフロー」と呼ばれる）では、フォームフィールドとして`username`と`password`を送信する必要があります。

## Using `WSGIMiddleware` { #using-wsgimiddleware }

You need to import `WSGIMiddleware`.

Then wrap the WSGI (e.g. Flask) app with the middleware.

And then mount that under a path.

{* ../../docs_src/wsgi/tutorial001_py39.py hl[2:3,3] *}

## Check it { #check-it }

Now, every request under the path `/v1/` will be handled by the Flask application.

And the rest will be handled by **FastAPI**.
