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" { #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.

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

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>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

		case "Version":
			z.Version, err = dc.ReadString()
			if err != nil {
				err = msgp.WrapError(err, "Version")
				return

		case "Format":
			z.Format, err = dc.ReadString()

		case "Stat":
			err = z.Stat.DecodeMsg(dc)
