    ```Python hl_lines="21"

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

    !!! tip "Заметка"
        Рекомендуется использовать `Annotated` версию, если это возможно.

### Generate the OpenAPI schema

Then, use the same utility function to generate the OpenAPI schema, inside a `custom_openapi()` function:

```Python hl_lines="2  15-21"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### Modify the OpenAPI schema

Now you can add the ReDoc extension, adding a custom `x-logo` to the `info` "object" in the OpenAPI schema:

    但是通过将类型声明为Session，编辑器现在可以知道可用的方法（.add()、.query()、.commit()等）并且可以提供更好的支持（比如完成）。类型声明不影响实际对象。

### 创建您的**FastAPI** *路径操作*

现在，到了最后，编写标准的**FastAPI** *路径操作*代码。

=== "Python 3.9+"

    ```Python hl_lines="21-26  29-32  35-40  43-47  50-53"
    {!> ../../../docs_src/sql_databases/sql_app_py39/main.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="23-28  31-34  37-42  45-49  52-55"

=== "Python 3.9+"

    ```Python hl_lines="22"
    {!> ../../../docs_src/dependencies/tutorial011_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="21"
    {!> ../../../docs_src/dependencies/tutorial011_an.py!}
    ```

=== "Python 3.8+ nicht annotiert"

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

    {!> ../../../docs_src/schema_extra_example/tutorial004_py310.py!}
    ```

=== "Python 3.8+ Annotated가 없는 경우"

    !!! tip "팁"
        가능하다면 `Annotated`가 달린 버전을 권장합니다.

    ```Python hl_lines="21-36"
    {!> ../../../docs_src/schema_extra_example/tutorial004.py!}
    ```

이와 같이 하면 이 예제는 그 본문 데이터를 위한 내부 **JSON 스키마**의 일부가 될 것입니다.

### Include a *path operation*

We can also add *path operations* directly to the `FastAPI` app.

Here we do it... just to show that we can 🤷:

```Python hl_lines="21-23" title="app/main.py"
{!../../../docs_src/bigger_applications/app/main.py!}
```

and it will work correctly, together with all the other *path operations* added with `app.include_router()`.

=== "Python 3.9+"

    ```Python hl_lines="17  19-21"
    {!> ../../../docs_src/settings/app02_an_py39/main.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="17  19-21"
    {!> ../../../docs_src/settings/app02_an/main.py!}
    ```

=== "Python 3.8+ nicht annotiert"

    !!! tip "Tipp"

## `Path`, `Query` 및 본문 매개변수 혼합

당연하게 `Path`, `Query` 및 요청 본문 매개변수 선언을 자유롭게 혼합해서 사용할 수 있고, **FastAPI**는 어떤 동작을 할지 압니다.

또한, 기본 값을 `None`으로 설정해 본문 매개변수를 선택사항으로 선언할 수 있습니다.

```Python hl_lines="19-21"
{!../../../docs_src/body_multiple_params/tutorial001.py!}
```

!!! note "참고"
    이 경우에는 본문으로 부터 가져온 `	item`은 기본값이 `None`이기 때문에, 선택사항이라는 점을 유의해야 합니다.

## 다중 본문 매개변수

    * de la recherche
    * de l'inspection

## Utilisez le modèle

Dans la fonction, vous pouvez accéder à tous les attributs de l'objet du modèle directement :

```Python hl_lines="21"
{!../../../docs_src/body/tutorial002.py!}
```

## Corps de la requête + paramètres de chemin

Vous pouvez déclarer des paramètres de chemin et un corps de requête pour la même *opération de chemin*.
