Теперь мы можем изменить зависимость `common_parameters`, указанную выше, на класс `CommonQueryParams`:

=== "Python 3.10+"

    ```Python hl_lines="11-15"
    {!> ../../../docs_src/dependencies/tutorial002_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="11-15"
    {!> ../../../docs_src/dependencies/tutorial002_an_py39.py!}
    ```

=== "Python 3.6+"

    ```Python hl_lines="12-16"

매개변수가 없는 "호출 가능"한 것 역시 매개변수가 없는 *경로 작동 함수*와 동일한 방식으로 적용됩니다.

그래서, 우리는 위 예제에서의 `common_paramenters` 의존성을 클래스 `CommonQueryParams`로 바꿀 수 있습니다.

=== "파이썬 3.6 이상"

    ```Python hl_lines="11-15"
    {!> ../../../docs_src/dependencies/tutorial002.py!}
    ```

=== "파이썬 3.10 이상"

    ```Python hl_lines="9-13"
    {!> ../../../docs_src/dependencies/tutorial002_py310.py!}
    ```

=== "Python 3.10+"

    ```Python hl_lines="11-15"
    {!> ../../../docs_src/dependencies/tutorial002_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="11-15"
    {!> ../../../docs_src/dependencies/tutorial002_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="12-16"

=== "Python 3.10+"

    ```Python hl_lines="11-15"
    {!> ../../../docs_src/dependencies/tutorial002_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="11-15"
    {!> ../../../docs_src/dependencies/tutorial002_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="12-16"

=== "Python 3.10+"

    ```Python hl_lines="9-13"
    {!> ../../../docs_src/dependencies/tutorial002_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="11-15"
    {!> ../../../docs_src/dependencies/tutorial002.py!}
    ```

注意用于创建类实例的 `__init__` 方法：

=== "Python 3.10+"

    ```Python hl_lines="10"
    {!> ../../../docs_src/dependencies/tutorial002_py310.py!}
