PayPal IPN監聽器不工作

因此，我已閱讀IPN文檔，並且已經閱讀了大量我找到的示例。我嘗試了幾種不同的解決方案，並且在他們不工作後，I've simply copy and pasted exactly what is documented on the PayPal IPN page.因此，它仍然無法正常工作。我的IPN歷史記錄顯示它正在繼續重新發送消息。下面的代碼 - 缺少什麼？PayPal IPN監聽器不工作

protected void Page_Load(object sender, EventArgs e) 
    { 
     const string postUrl = "https://www.paypal.com/cgi-bin/webscr"; 
     var req = (HttpWebRequest)WebRequest.Create(postUrl); 

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

     //for proxy 
     //WebProxy proxy = new WebProxy(new Uri("http://url:port#")); 
     //req.Proxy = proxy; 

     //Send the request to PayPal and get the response 
     var streamOut = new StreamWriter(req.GetRequestStream(), Encoding.ASCII); 
     streamOut.Write(strRequest); 
     streamOut.Close(); 

     // ReSharper disable AssignNullToNotNullAttribute 
     var streamIn = new StreamReader(req.GetResponse().GetResponseStream()); 
     // ReSharper restore AssignNullToNotNullAttribute 
     var strResponse = streamIn.ReadToEnd(); 
     streamIn.Close(); 

     // logging ipn messages... be sure that you give write 
     // permission to process executing this code 
     // 

     if (strResponse == "VERIFIED") 
     { 
      //check the payment_status is Completed 
      //check that txn_id has not been previously processed 
      //check that receiver_email is your Primary PayPal email 
      //check that payment_amount/payment_currency are correct 
      //process payment 
      var mailer = new Emailer(); 
      mailer.SendMail("[email protected]", "[email protected]", "Thank you!", 
          "Thank you for your sponsorship. Good luck on your results!<br /><br />" + ipnPost); 
     } 
     else if (strResponse == "INVALID") 
     { 
      //log for manual investigation 
     } 
    }

如果您訪問PayPal網站上的IPN模擬器，狀態如何？「 – Paul

」IPN傳遞失敗，無法連接到指定的URL，請驗證URL並重試。 - 從我讀過的內容來看，這意味着PayPal不喜歡聽衆上的代碼..這很奇怪，看起來就像是他們在示例中給出的代碼... – r584

原來，這是我的電子郵件發件人的錯誤。我從AWS發送的地址未在我的AWS賬戶中驗證。

因此，您的腳本因服務器而犯錯設置，並因此返回HTTP 200/302-> 200響應以外的內容。（如果您的腳本返回HTTP200或302重定向到200，IPN只認爲消息已成功發送） – SgtPooki
