이제 아래의 클래스를 이용해서 의존성을 정의할 수 있습니다.

=== "파이썬 3.6 이상"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial002.py!}
    ```

=== "파이썬 3.10 이상"

    ```Python hl_lines="17"
    {!> ../../../docs_src/dependencies/tutorial002_py310.py!}
    ```

**FastAPI**는 `CommonQueryParams` 클래스를 호출합니다. 이것은 해당 클래스의 "인스턴스"를 생성하고 그 인스턴스는 함수의 매개변수 `commons`로 전달됩니다.

## 타입 힌팅 vs `Depends`

    ```

=== "Python 3.10+ без Annotated"

    !!! tip "Подсказка"
        Рекомендуется использовать версию с `Annotated` если возможно.

    ```Python hl_lines="17"
    {!> ../../../docs_src/dependencies/tutorial002_py310.py!}
    ```

=== "Python 3.6+ без Annotated"

    !!! tip "Подсказка"
        Рекомендуется использовать версию с `Annotated` если возможно.

    ```

=== "Python 3.10+ nicht annotiert"

    !!! tip "Tipp"
        Bevorzugen Sie die `Annotated`-Version, falls möglich.

    ```Python hl_lines="17"
    {!> ../../../docs_src/dependencies/tutorial002_py310.py!}
    ```

=== "Python 3.8+ nicht annotiert"

    !!! tip "Tipp"
        Bevorzugen Sie die `Annotated`-Version, falls möglich.

* 一个 `limit` 查询参数，是 `int` 类型，默认值为 `100`。

在两个例子下，数据都将被转换、验证、在 OpenAPI schema 上文档化，等等。

## 使用它

现在，您可以使用这个类来声明你的依赖项了。

=== "Python 3.10+"

    ```Python hl_lines="17"
    {!> ../../../docs_src/dependencies/tutorial002_py310.py!}
    ```

=== "Python 3.6+"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial002.py!}
    ```

=== "🐍 3️⃣.6️⃣ & 🔛"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial002.py!}
    ```

=== "🐍 3️⃣.1️⃣0️⃣ & 🔛"

    ```Python hl_lines="17"
    {!> ../../../docs_src/dependencies/tutorial002_py310.py!}
    ```

=== "Python 3.10+ non-Annotated"

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