Paypal的notify_url沒有返回一個值，也沒有插入數據庫

我的問題是Notify_url不會在數據庫中插入任何值。任何人都可以告訴我我錯在哪裏。我有以下可用Paypal的notify_url沒有返回一個值，也沒有插入數據庫

代碼的網頁我有三個頁面：1）的Default.aspx 2）sendpayment.aspx 3）PAypal.aspx

Default.aspx中，我有兩個文本框。我得到了會議這兩個值和提交我重定向頁面Sendpayment.aspx

在sendpayment.aspx，我有以下代碼

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Sendpayment.aspx.vb" Inherits="Sendpayment" Debug="true" %> 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head id="Head1" runat="server"> 
<title>Untitled Page</title> 
</head> 
<body> 

<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" id="form1" 
    name="form1"> 
    <input type="hidden" name="cmd" value="_xclick"/> 
    <input type="hidden" name="business" value="[email protected]"/><!--Paypal or sandbox Merchant account --> 

    <input type="hidden" name="custom" value="<%=Session("regemail")%>"/><!--Custom Field for payer email --> 
    <input type="hidden" name="item_number" value="1"/> 
    <input type="hidden" name="amount" value="<%=Session("totalShoppingAmt")%>"/> 
    <input type="hidden" name="notify_url" value="http://www.abc.com/paypal.aspx"/><!--this should be your domain web page where you going to receive all your transaction variables --> 
    <input type="hidden" name="return" value="http://www.abc.com/thankyou.html"/><!--this page will be your redirection page --> 
    <input type="hidden" name="cancel_return" value="http://www.abc.com"/> 
    <input type="hidden" name="currency_code" value="USD"/> 

</form> 

<script type="text/jscript"> 
    document.form1.submit(); 
</script>

我必須在指定通知http://www.abc.com/paypal.aspx網址

在Paypal.aspx，

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Paypal.aspx.vb" Inherits="Paypal" Debug="true" %> 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<form id="form1" runat="server">

檢查IPN歷史在您的支付寶，看看什麼是越來越發送與否。您可能會發現它正在顯示它正在發送數據，但卻收到了不好的迴應。

如果顯示它正在發送數據，但獲取200響應以外的任何內容，那麼需要修復的腳本有問題。你可以檢查你的Web服務器日誌尋求幫助，或者我想要做的是構建一個HTML表單，其中的動作設置爲我的IPN腳本以及一些與我期望從IPN獲得的隱藏字段相匹配的隱藏字段。然後我在瀏覽器中提交，並實際在屏幕上看到可幫助解決問題的結果。

一旦它的工作方式，你知道你很好。請記住，當您這樣做時，數據不會來自PayPal，因此無法成功驗證。您需要確保您的代碼邏輯可以處理該問題。

如果您的IPN歷史記錄沒有顯示任何內容正在發送，那麼我會質疑您是否正在查看正確的沙盒帳戶。很容易讓他們感到困惑，並且看錯了一個。

正如您所說的YE IPN歷史顯示爲每筆交易發送。但我沒有得到任何東西。我正在使用沙箱帳戶從https://developer.paypal.com/webapps/developer/applications/accounts 我使用正確的沙箱帳戶？如果不是，我應該使用哪個？ –
