### `Query` 임포트

이를 위해 먼저 `fastapi`에서 `Query`를 임포트합니다:

```Python hl_lines="3"
{!../../../docs_src/query_params_str_validations/tutorial002.py!}
```

## 기본값으로 `Query` 사용

이제 `Query`를 매개변수의 기본값으로 사용하여 `max_length` 매개변수를 50으로 설정합니다:

```Python hl_lines="9"
{!../../../docs_src/query_params_str_validations/tutorial002.py!}
```

=== "Python 3.10+"

    ```Python hl_lines="68-69  82"
    {!> ../../../docs_src/websockets/tutorial002_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="68-69  82"
    {!> ../../../docs_src/websockets/tutorial002_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="69-70  83"
    {!> ../../../docs_src/websockets/tutorial002_an.py!}
    ```

首先，导入 `Header`：

    ```Python hl_lines="3"

    ```

=== "Python 3.9+"

    ```Python hl_lines="3"
    {!> ../../../docs_src/header_params/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="3"
    {!> ../../../docs_src/header_params/tutorial001_an.py!}
    ```

=== "Python 3.10+ non-Annotated"

### Check the docs

Now you can start your app and go to <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

You will see your docs have the normal *path operations* and now also some **webhooks**:

=== "Python 3.10+"

    ```Python hl_lines="13-21"
    {!> ../../../docs_src/schema_extra_example/tutorial001_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="15-23"
    {!> ../../../docs_src/schema_extra_example/tutorial001.py!}
    ```
