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`.

///

/// tip | Dica

{* ../../docs_src/request_forms_and_files/tutorial001.py hl[8] *}

ファイルとフォームフィールドがフォームデータとしてアップロードされ、ファイルとフォームフィールドを受け取ります。

また、いくつかのファイルを`bytes`として、いくつかのファイルを`UploadFile`として宣言することができます。

/// warning | 注意

*path operation*で複数の`File`と`Form`パラメータを宣言することができますが、JSONとして受け取ることを期待している`Body`フィールドを宣言することはできません。なぜなら、リクエストのボディは`application/json`の代わりに`multipart/form-data`を使ってエンコードされているからです。

これは **FastAPI** の制限ではなく、HTTPプロトコルの一部です。

///

Estos son objetos de **JavaScript**, no strings, por lo que no puedes pasarlos directamente desde código de Python.

```Python
q: Union[str, None] = Query(default=None, max_length=50)
```

Cela va valider les données, montrer une erreur claire si ces dernières ne sont pas valides, et documenter le paramètre dans le schéma `OpenAPI` de cette *path operation*.

## Rajouter plus de validation

Vous pouvez aussi rajouter un second paramètre `min_length` :

{* ../../docs_src/query_params_str_validations/tutorial003.py hl[9] *}

```JSON
{
    "detail": [
        {
            "loc": [
                "path",
                "item_id"
            ],
            "msg": "value is not a valid integer",
            "type": "type_error.integer"
        }
    ]
}
```

você receberá a versão em texto:

```
Validation errors:
Field: ('path', 'item_id'), Error: Input should be a valid integer, unable to parse string as an integer
