```

=== "Python 3.8+"

    ```Python hl_lines="23-28"
    {!> ../../../docs_src/schema_extra_example/tutorial003_an.py!}
    ```

=== "Python 3.10+ non-Annotated"

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

    ```Python hl_lines="18-23"
    {!> ../../../docs_src/schema_extra_example/tutorial003_py310.py!}
    ```

### 다중 `examples`를 포함한 `Body`

물론 여러 `examples`를 넘길 수 있습니다:

=== "Python 3.10+"

    ```Python hl_lines="23-38"
    {!> ../../../docs_src/schema_extra_example/tutorial004_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="23-38"
    {!> ../../../docs_src/schema_extra_example/tutorial004_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24-39"

### `Body` mit mehreren `examples`

Sie können natürlich auch mehrere `examples` übergeben:

=== "Python 3.10+"

    ```Python hl_lines="23-38"
    {!> ../../../docs_src/schema_extra_example/tutorial004_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="23-38"
    {!> ../../../docs_src/schema_extra_example/tutorial004_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24-39"

### `Body` with multiple `examples`

You can of course also pass multiple `examples`:

=== "Python 3.10+"

    ```Python hl_lines="23-38"
    {!> ../../../docs_src/schema_extra_example/tutorial004_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="23-38"
    {!> ../../../docs_src/schema_extra_example/tutorial004_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24-39"

=== "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"
    {!> ../../../docs_src/sql_databases/sql_app/main.py!}
    ```

我们在依赖项中的每个请求之前利用`yield`创建数据库会话，然后关闭它。

所以我们就可以在*路径操作函数*中创建需要的依赖，就能直接获取会话。

Но вы можете указать **FastAPI** обрабатывать его, как ещё один ключ тела запроса, используя `Body`:

=== "Python 3.10+"

    ```Python hl_lines="23"
    {!> ../../../docs_src/body_multiple_params/tutorial003_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="23"
    {!> ../../../docs_src/body_multiple_params/tutorial003_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24"

### 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()`.

burgers = get_burgers(2)
```

---

Então, se você está usando uma biblioteca que diz que você pode chamá-la com `await`, você precisa criar as *funções de operação de rota* com `async def`, como em:

```Python hl_lines="2 3"
@app.get('/burgers')
async def read_burgers():
    burgers = await get_burgers(2)
    return burgers
```

### Mais detalhes técnicos

                </mxCell>
                <mxCell id="25" style="edgeStyle=orthogonalEdgeStyle;rounded=0;orthogonalLoop=1;jettySize=auto;html=1;endArrow=none;endFill=0;strokeWidth=3;" parent="1" source="12" target="23" edge="1">
                    <mxGeometry relative="1" as="geometry"/>
                </mxCell>

但这只会影响我们应用中的 `APIRouter`，而不会影响使用它的任何其他代码。

因此，举例来说，其他项目能够以不同的身份认证方法使用相同的 `APIRouter`。

### 包含一个*路径操作*

我们还可以直接将*路径操作*添加到 `FastAPI` 应用中。

这里我们这样做了...只是为了表明我们可以做到🤷：

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

它将与通过 `app.include_router()` 添加的所有其他*路径操作*一起正常运行。
