System.IO.File.AppendAllText(Server.MapPath("~/App_Data/log.txt"), " rateCount: " + "米亞回調"+DateTime.Now.ToString());
if (sPara.Count > 0)//判斷是否有帶返回參數
{
Notify aliNotify = new Notify();
bool verifyResult = aliNotify.Verify(sPara, Request.Form["notify_id"], Request.Form["sign"]);

if (verifyResult)//驗證成功
{
