                        Regex reg = new Regex(@"http(s)?://([\w-]+\.)+[\w-]+(/[\w-./?%&=]*)?");
                        Match match = reg.Match(model.CloudFavoriteLink);
                        if (match.Value == "")
                        {
                            //相關處理或提示代碼

                        }
