## `BackgroundTasks` の使用

まず初めに、`BackgroundTasks` をインポートし、` BackgroundTasks` の型宣言と共に、*path operation 関数* のパラメーターを定義します:

```Python hl_lines="1  13"
{!../../docs_src/background_tasks/tutorial001.py!}
```

**FastAPI** は、`BackgroundTasks` 型のオブジェクトを作成し、そのパラメーターに渡します。

## タスク関数の作成

# 请求体 - 多个参数

既然我们已经知道了如何使用 `Path` 和 `Query`，下面让我们来了解一下请求体声明的更高级用法。

## 混合使用 `Path`、`Query` 和请求体参数

首先，毫无疑问地，你可以随意地混合使用 `Path`、`Query` 和请求体参数声明，**FastAPI** 会知道该如何处理。

你还可以通过将默认值设置为 `None` 来将请求体参数声明为可选参数：

```Python hl_lines="18-20"
{!> ../../docs_src/body_multiple_params/tutorial001_an_py310.py!}
```

```Python hl_lines="18-20"

        ("/items?q=foo&skip=5&limit=30", 200, {"q": "foo", "skip": 5, "limit": 30}),
        ("/users", 200, {"q": None, "skip": 0, "limit": 100}),
    ],
)
