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.

## 단일 본문 매개변수 삽입하기

Pydantic 모델 `Item`의 `item`을 본문 매개변수로 오직 한개만 갖고있다고 하겠습니다.

O `secrets.compare_digest()` necessita receber `bytes` ou `str` que possuem apenas caracteres ASCII (os em inglês). Isso significa que não funcionaria com caracteres como o `á`, como em `Sebastián`.

   *                  str -> str.charAt(0),
   *                  str -> str.substring(1),
   *                  MultimapBuilder.treeKeys().arrayListValues()::build));

   * static final ListMultimap<Character, String> FIRST_LETTER_MULTIMAP;
