                cookies.Values[keys] = values;
                DateTime dts = DateTime.Now;//定义时间对象
                TimeSpan ts = new TimeSpan(0, 0, 20, 0);//cookie有效作用时间
                cookies.Expires = dts.Add(ts);//添加作用时间
                //cookies.Domain = ".hnzbtb.com"; 下级域名通用
                page.Response.Cookies.Add(cookies);
