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

이전 예제에서 보듯이, *경로 작동*은 아래와 같이 `Item` 속성을 가진 JSON 본문을 예상합니다:
