## Definir parámetros de `Form` { #define-form-parameters }

Crea parámetros de formulario de la misma manera que lo harías para `Body` o `Query`:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[9] *}

With `Form` you can declare the same configurations as with `Body` (and `Query`, `Path`, `Cookie`), including validation, examples, an alias (e.g. `user-name` instead of `username`), etc.

/// 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.

///

	for i, testCase := range testCases {
		// Turn the map[string]string into map[string][]string, because Go.
		query := url.Values{}
		for key, value := range testCase.queryParams {
			query.Set(key, value)
		}
		// Create a request to use.
		req, err := http.NewRequest(http.MethodGet, "http://host/a/b?"+query.Encode(), nil)
		if err != nil {
			t.Errorf("(%d) failed to create http.Request, got %v", i, err)
		}
