기본적으로 단일 값은 쿼리 매개변수로 해석되므로, 명시적으로 `Query`를 추가할 필요가 없고, 아래처럼 할 수 있습니다:

{* ../../docs_src/body_multiple_params/tutorial004.py hl[27] *}

이렇게:

```Python
q: Optional[str] = None
```

/// info | 정보

`Body` 또한 `Query`, `Path` 그리고 이후에 볼 다른 것들처럼 동일한 추가 검증과 메타데이터 매개변수를 갖고 있습니다.

///

## 단일 본문 매개변수 삽입하기

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[8] *}

Those parameters are what **FastAPI** will use to "solve" the dependency.

In both cases, it will have:

* An optional `q` query parameter that is a `str`.
* A `skip` query parameter that is an `int`, with a default of `0`.
* A `limit` query parameter that is an `int`, with a default of `100`.
