h5微信支付在获取openid页面需要传参数进来，但是在获取openid后，刷新页面，参数丢失了，这个怎么处理。就差这一步了，这一步成功，整个支付就算完成了。



//获取当前用户的OpenId，如果可以通过系统获取用户Openid就不用调用该函数

            this.GetUserOpenId();

            this.lblOpenId.Text = this.UserOpenId;

            LogUtil.WriteLog("Send 页面  pdf：" + Request.QueryString["pdf"].ToString());



            string pdf = "";

            string id = "";

            string qx = "";

            string pid = "";

            if (Request.QueryString["pdf"] != null)

              pdf = Request.QueryString["pdf"].ToString();

            if (Request.QueryString["id"] != null)

                id = Request.QueryString["id"].ToString();

            if (Request.QueryString["qx"] != null)

                qx = Request.QueryString["qx"].ToString();

            if (Request.QueryString["pid"] != null)

                pid = Request.QueryString["pid"].ToString();



            //this.GetUserOpenId();



            //this.lblOpenId.Text = this.UserOpenId;



            Response.Write(pdf + id + qx + pid + "aa");

            Response.End();

            //设置支付数据

            PayModel model = new PayModel();

            model.OrderSN = this.txtOrderSN.Text;

            model.TotalFee = int.Parse(this.txtPrice.Text);

            model.Body = pdf;// this.txtBody.Text;

            model.Attach = this.txtOther.Text; //不能有中文

            model.OpenId = "";// Request.QueryString["openid"].ToString();// "o2lm6uMVUTvmeyMzhBRvAFE465V8";// this.lblOpenId.Text;

            model.pdf = pdf;

            model.id = id;

            model.qx = qx;

            model.pid = pid;

            //string pdf = Request.QueryString["pdf"].ToString();

            //跳转到 WeiPay.aspx 页面，请设置函数中WeiPay.aspx的页面地址

            this.Response.Redirect(model.ToString());
