Description

gin/binding/form.go

func (formBinding) Bind(req *http.Request, obj interface{}) error {
	if err := req.ParseForm(); err != nil {
		return err
	}
	req.ParseMultipartForm(defaultMemory)
	if err := mapForm(obj, req.Form); err != nil {
		return err
	}
	return validate(obj)
}

req.ParseMultipartForm(defaultMemory) should return error

As I see, should return error except one - http.ErrNotMultipart.
Because formBinding used not only for multipart form.
