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

```Python hl_lines="27"
{!../../docs_src/body_multiple_params/tutorial004.py!}
```

이렇게:

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

/// info | "정보"

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

Diese Parameter werden von **FastAPI** verwendet, um die Abhängigkeit „aufzulösen“.

In beiden Fällen wird sie haben:

* Einen optionalen `q`-Query-Parameter, der ein `str` ist.
* Einen `skip`-Query-Parameter, der ein `int` ist, mit einem Defaultwert `0`.
* Einen `limit`-Query-Parameter, der ein `int` ist, mit einem Defaultwert `100`.
