## Получение данных пользователя

`get_current_user` будет использовать созданную нами (ненастоящую) служебную функцию, которая принимает токен в виде `строки` и возвращает нашу Pydantic-модель `User`:

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## Внедрение зависимости текущего пользователя

Und versuchen Sie, die Operation `GET` mit dem Pfad `/users/me` zu verwenden.

Sie erhalten die Fehlermeldung „Inactive user“:

```JSON

  "detail": "Inactive user"
}
```
