Paypal以500错误响应IPN验证

每隔一段时间,Paypal就会向我的.net应用程序ipn脚本返回500错误代码。它将在验证请求的响应中返回该代码

以下是记录的错误:

System.Net.WebException 远程服务器返回错误:(500)内部服务器错误。

System.Web.HttpUnhandledException(0x80004005):抛出了类型为“System.Web.HttpUnhandledException”的异常。 ---> System.Net.WebException:远程服务器返回错误:(500)内部服务器错误。    在System.Net.HttpWebRequest.GetResponse()    在ASP.ipn_aspx.Page_Load(Object sender,EventArgs e)

我用于通话的代码是:

  endPoint = "https://www.paypal.com/cgi-bin/webscr";
  HttpWebRequest req = (HttpWebRequest)WebRequest.Create(endPoint);

  //Set values for the request back
  req.Method = "POST";
  req.ContentType = "application/x-www-form-urlencoded";
  byte[] param = Request.BinaryRead(HttpContext.Current.Request.ContentLength);
  string strRequest = Encoding.ASCII.GetString(param);
  strRequest += "&cmd=_notify-validate";
  req.ContentLength = strRequest.Length;

  //Send the request to PayPal and get the response
  StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
  streamOut.Write(strRequest);
  streamOut.Close();
  StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
  string strResponse = streamIn.ReadToEnd();
  streamIn.Close();

这可能每天发生一次,而PayPal不会重试ipn消息。其他95%的PayPal ipn交易正常运作。有什么想法吗?
