!!! info
    `Form` is a class that inherits directly from `Body`.

!!! tip
    To declare form bodies, you need to use `Form` explicitly, because without it the parameters would be interpreted as query parameters or body (JSON) parameters.

## About "Form Fields"

The way HTML forms (`<form></form>`) sends the data to the server normally uses a "special" encoding for that data, it's different from JSON.

		}
		args[i] = arg
	}
	return fmt.Sprintf(format, args...)
}

// check may be nil.
func (check *Checker) sprintf(format string, args ...any) string {
	var fset *token.FileSet
	var qf Qualifier
	if check != nil {
		fset = check.fset
		qf = check.qualifier
	}
	return sprintf(fset, qf, false, format, args...)
}

func (check *Checker) trace(pos token.Pos, format string, args ...any) {
	fmt.Printf("%s:\t%s%s\n",

//
//  Examples:
//      format.dns1123Label().validate("my-label-name")
//      format.dns1123Subdomain().validate("apiextensions.k8s.io")
//      format.dns1035Label().validate("my-label-name")
//      format.qualifiedName().validate("apiextensions.k8s.io/v1beta1")
//      format.dns1123LabelPrefix().validate("my-label-prefix-")
//      format.dns1123SubdomainPrefix().validate("mysubdomain.prefix.-")

# Request Forms and Files

You can define files and form fields at the same time using `File` and `Form`.

!!! info
    To receive uploaded files and/or form data, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

    E.g. `pip install python-multipart`.

## Import `File` and `Form`

=== "Python 3.9+"

    ```Python hl_lines="3"

Com `Form` você pode declarar os mesmos metadados e validação que com `Body` (e `Query`, `Path`, `Cookie`).

!!! info "Informação"
    `Form` é uma classe que herda diretamente de `Body`.

// check may be nil.
func (check *Checker) sprintf(format string, args ...any) string {

	if check != nil {

	}

}

func (check *Checker) trace(pos syntax.Pos, format string, args ...any) {
	fmt.Printf("%s:\t%s%s\n",
		pos,

	}
}

// fmtFloat formats a float64. It assumes that verb is a valid format specifier
// for strconv.AppendFloat and therefore fits into a byte.
func (f *fmt) fmtFloat(v float64, size int, verb rune, prec int) {
	// Explicit precision in format specifier overrules default precision.
	if f.precPresent {
		prec = f.prec
	}
	// Format number, reserving space for leading + sign if needed.

// when used with time.Parse they do not accept all the time formats
// permitted by the RFCs and they do accept time formats not formally defined.
// The [RFC3339Nano] format removes trailing zeros from the seconds field
// and thus may not sort correctly once formatted.
//
// Most programs can use one of the defined constants as the layout passed to
// Format or Parse. The rest of this comment can be ignored unless you are

`Form`では`Body`（および`Query`や`Path`、`Cookie`）と同じメタデータとバリデーションを宣言することができます。

!!! info "情報"
    `Form`は`Body`を直接継承するクラスです。

!!! tip "豆知識"
    フォームのボディを宣言するには、明示的に`Form`を使用する必要があります。なぜなら、これを使わないと、パラメータはクエリパラメータやボディ（JSON）パラメータとして解釈されるからです。

## 「フォームフィールド」について

HTMLフォーム（`<form></form>`）がサーバにデータを送信する方法は、通常、そのデータに「特別な」エンコーディングを使用していますが、これはJSONとは異なります。
