}

다음 대신에:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

## 정리 { #recap }

요청은 본문을 하나만 가질 수 있지만, *경로 처리 함수*에 다중 본문 매개변수를 추가할 수 있습니다.

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    }
}
```

而不是：

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

## 总结 { #recap }

你可以添加多个请求体参数到*路径操作函数*中，即使一个请求只能有一个请求体。
