我的IPN列表工具无效。当我尝试使用IPN列表时错误显示如下“我们很抱歉，我们无法发送IPN。” 但我可以从浏览器访问IPN处理程序URL。

这是我的IPN处理程序代码。

  public ActionResult IPN()
    {
        LogMessage ("entering ipn action ");
        var formVals = new Dictionary<string, string>();
        formVals.Add("cmd", "_notify-validate");

        string response = GetPayPalResponse(formVals, true);
        LogMessage ("IPN Response received: " + response + " <-- That was response. . . ");

        if (response == "VALID")
        {
            LogMessage("Response Was Verified");
        }

        else
        {
            LogMessage("RESPONSE WAS NOT VERIFIED");
        }

        return Json("Sucess",JsonRequestBehavior.AllowGet);
    }

 string GetPayPalResponse(Dictionary<string, string> formVals, bool useSandbox)
    {
        string paypalUrl = useSandbox
                                ? "https://www.sandbox.paypal.com/cgi-bin/webscr"
                                : "https://www.paypal.com/cgi-bin/webscr";

        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(paypalUrl);

        //Set values for the request back
        req.Method = "POST";
        req.ContentType = "application/x-www-form-urlencoded";

        byte[] param = Request.BinaryRead(Request.ContentLength);
        string strRequest = Encoding.ASCII.GetString(param);

        StringBuilder sb = new StringBuilder();
        sb.Append(strRequest);

        foreach (string key in formVals.Keys)
        {
            sb.AppendFormat("&{0}={1}", key, formVals[key]);
        }
        strRequest += sb.ToString();
        req.ContentLength = strRequest.Length;

        string response = "";
        using (StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII))
        {
            streamOut.Write(strRequest);
            streamOut.Close();
            using (StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream()))
            {
                response = streamIn.ReadToEnd();
            }
        }
        return response;
    }
