asp.net网站集成支付宝接口,支付成功后收不到通知
这是Alipay_Return.aspx.cs
namespace
{
    public partial class Alipay_Return : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Page.Title = "支付结果";

            string alipayNotifyURL = "https://www.

            string key = "自己的key"; //partner 的对应交易安全校验码(必须填写)
            string partner = "自己的partner"; //partner合作伙伴id(必须填写)
            string _input_charset = "utf-8";//编码类型,完全根据客户自身的项目的编码格式而定,千万不要填错。否则极其容易造成MD5加密错误。
            alipayNotifyURL = alipayNotifyURL + "&partner=" + partner + "&notify_id=" + Request.QueryString["notify_id"];

            //获取支付宝ATN返回结果,true是正确的订单信息,false 是无效的
            string responseTxt = AliPay.Get_Http(alipayNotifyURL, 120000);

            int i;
            NameValueCollection coll;
            //Load Form variables into NameValueCollection variable.
            coll = Request.QueryString;
            // Get names of all forms into a string array.
            String[] requestarr = coll.AllKeys;
            //进行排序;
            string[] Sortedstr = AliPay.BubbleSort(requestarr);
            //构造待md5摘要字符串 ;
            StringBuilder prestr = new StringBuilder();

            for (i = 0; i < Sortedstr.Length; i++)
            {
                if (Request.Form[Sortedstr[i]] != "" && Sortedstr[i] != "sign" && Sortedstr[i] != "sign_type")
                {
                    if (i == Sortedstr.Length - 1)
                    {
                        prestr.Append(Sortedstr[i] + "=" + Request.QueryString[Sortedstr[i]]);
                    }
                    else
                    {
                        prestr.Append(Sortedstr[i] + "=" + Request.QueryString[Sortedstr[i]] + "&");
                    }
                }
            }
            prestr.Append(key);
            //生成Md5摘要;
            string mysign = AliPay.GetMD5(prestr.ToString(), _input_charset);
            //*******加密签名程序结束*******
            string sign = Request.QueryString["sign"];

            if (mysign == sign && responseTxt == "true")
            {
                //更新自己数据库的订单语句,请自己填写一下
                string strOrderNO = Request.QueryString["out_trade_no"].ToString();//订单号
                string OrderNo = strOrderNO.Substring(strOrderNO.IndexOf('m') + 1);
                int orderNo = Convert.ToInt32(OrderNo);
                UserInfoCom userInfoCom = UserInfoComManager.GetUserInfoByUserIDCom(Convert.ToInt32(orderNo));

                if (userInfoCom.Active == 1)
                {
                    Response.Write("success");
                    return;
                }
          }
    }
}
这是Alipay_Notify.aspx.cs
namespace
{
    public partial class Alipay_Notify : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
             //string alipayNotifyURL = "http://notify.

            string _input_charset = "utf-8";//编码类型,完全根据客户自身的项目的编码格式而定,千万不要填错。否则极其容易造成MD5加密错误。
            alipayNotifyURL = alipayNotifyURL + "&partner=" + partner + "&notify_id=" + Request.Form["notify_id"];
            ////获取支付宝ATN返回结果,true是正确的订单信息,false 是无效的
            string responseTxt = AliPay.Get_Http(alipayNotifyURL, 120000);
            //*******加密签名程序开始*******
            int i;
            NameValueCollection coll;
            //Load Form variables into NameValueCollection variable.
            coll = Request.Form;
            // Get names of all forms into a string array.
            String[] requestarr = coll.AllKeys;
            //进行排序;
            string[] Sortedstr = AliPay.BubbleSort(requestarr);
            //构造待md5摘要字符串 ;
            StringBuilder prestr = new StringBuilder();
            for (i = 0; i < Sortedstr.Length; i++)
            {
                if (Request.Form[Sortedstr[i]] != "" && Sortedstr[i] != "sign" && Sortedstr[i] != "sign_type")
                {
                    if (i == Sortedstr.Length - 1)
                    {
                        prestr.Append(Sortedstr[i] + "=" + Request.Form[Sortedstr[i]]);
                    }
                    else
                    {
                        prestr.Append(Sortedstr[i] + "=" + Request.Form[Sortedstr[i]] + "&");
                    }
                }
            }
            prestr.Append(key);
            string mysign = AliPay.GetMD5(prestr.ToString(), _input_charset);
            //*******加密签名程序结束*******
            string sign = Request.Form["sign"];

            if (mysign == sign && responseTxt == "true")
            {
                //更新自己数据库的订单语句,请自己填写一下
                string strOrderNO = Request.Form["out_trade_no"];//订单号
                string OrderNo = strOrderNO.Substring(strOrderNO.IndexOf('m') + 1);
                int orderNo = Convert.ToInt32(OrderNo);
                UserInfoCom userInfoCom = UserInfoComManager.GetUserInfoByUserIDCom(Convert.ToInt32(orderNo));
            }
        }
    }
}
