1. Copy a same struct without binding,
2. Not use binding tag, replacing it by another check solution.
3. Realize a method you want, this is mine usecase for json.

// json bind
func BindWihtoutBindingTag(c *gin.Context, dest interface{}) error {
	if c.ContentType() != "application/json" {
		return errors.New("'BindWithoutBindingTag' only serves for application/json not for " + c.ContentType())
	}
	buf, e := ioutil.ReadAll(c.Request.Body)
	if e != nil {
		return e
	}
	c.Request.Body = ioutil.NopCloser(bytes.NewReader(buf))
	return json.Unmarshal(buf, dest)
}
