Mit `Form` haben Sie die gleichen Konfigurationsmöglichkeiten wie mit `Body` (und `Query`, `Path`, `Cookie`), inklusive Validierung, Beispielen, einem Alias (z. B. `user-name` statt `username`), usw.

/// info | Info

`Form` ist eine Klasse, die direkt von `Body` erbt.

Com `Form` você pode declarar as mesmas configurações que com `Body` (e `Query`, `Path`, `Cookie`), incluindo validação, exemplos, um alias (por exemplo, `user-name` em vez de `username`), etc.

/// info | Informação

`Form` é uma classe que herda diretamente de `Body`.

마치 다음과 같습니다:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

그러나 `item-query`은 유효한 파이썬 변수 이름이 아닙니다.

가장 가까운 것은 `item_query`일 겁니다.

하지만 정확히`item-query`이길 원합니다...

이럴 경우 `alias`를 선언할 수 있으며, 해당 별칭은 매개변수 값을 찾는 데 사용됩니다:

{* ../../docs_src/query_params_str_validations/tutorial009.py hl[9] *}

## 매개변수 사용하지 않게 하기

이제는 더이상 이 매개변수를 마음에 들어하지 않는다고 가정해 봅시다.
