=== "Python 3.8 non-Annotated"

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python
    commons: CommonQueryParams = Depends()
    ```

You declare the dependency as the type of the parameter, and you use `Depends()` without any parameter, instead of having to write the full class *again* inside of `Depends(CommonQueryParams)`.

    ```python
    from typing import Annotated

    from fastapi import Depends, FastAPI
    from fastapi.security import HTTPBasic, HTTPBasicCredentials

    app = FastAPI()

    security = HTTPBasic()


    @app.get("/users/me")
    def read_current_user(credentials: Annotated[HTTPBasicCredentials, Depends(security)]):
        return {"username": credentials.username, "password": credentials.password}

    ```Python hl_lines="15  20"
    {!> ../../../docs_src/dependencies/tutorial001.py!}
    ```

`Depends` работает немного иначе. Вы передаёте в `Depends` одиночный параметр, который будет похож на функцию.

Вы **не вызываете его** на месте (не добавляете скобочки в конце: 👎 *your_best_func()*👎), просто передаёте как параметр в `Depends()`.

И потом функция берёт параметры так же, как *функция обработки пути*.

!!! tip "Подсказка"

    ```

Although you use `Depends` in the parameters of your function the same way you use `Body`, `Query`, etc, `Depends` works a bit differently.

You only give `Depends` a single parameter.

This parameter must be something like a function.

You **don't call it** directly (don't add the parenthesis at the end), you just pass it as a parameter to `Depends()`.

    {!> ../../../docs_src/dependencies/tutorial001.py!}
    ```

비록 `Body`, `Query` 등을 사용하는 것과 같은 방식으로 여러분의 함수의 매개변수에 있는 `Depends`를 사용하지만, `Depends`는 약간 다르게 작동합니다.

`Depends`에 단일 매개변수만 전달했습니다.

이 매개변수는 함수같은 것이어야 합니다.

여러분은 직접 **호출하지 않았습니다** (끝에 괄호를 치지 않았습니다), 단지 `Depends()`에 매개변수로 넘겨 줬을 뿐입니다.

그리고 그 함수는 *경로 작동 함수*가 작동하는 것과 같은 방식으로 매개변수를 받습니다.
