## Получить пользователя { #get-the-user }

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

```Python hl_lines="1"
async def needy_dependency(fresh_value: Annotated[str, Depends(get_value, use_cache=False)]):
    return {"fresh_value": fresh_value}
```

////

//// tab | Python 3.9+ non-Annotated

/// tip

Prefer to use the `Annotated` version if possible.
