PHP贝宝API和沙盒问题

Question

也许愚蠢的问题..

我如何知道我的PayPal API集成是否正常工作？

我的意思是代码转到PayPal罚款，PayPal付款似乎工作正常，然后用户在付款后在我的网站上的正确页面重定向。

所以我假设它工作正常。

但是没有价格显示在PayPal表单上。

没有找到我的测试帐户收费

我的其他测试帐户（卖方）没有进帐

我假设它的作品只是因为用户被重定向到成功页面在我的网站！

但我怎么知道它真的在工作？！

没有什么让我完全确定它的作品！

请指教..

我现在用的是快速结账API

我justing收取客户的单个项目，没有贝宝授权等。只是一个简单的PayPal出售。

谢谢

须知Paypal IPN（即时付款通知）的测试良好的代码示例通过你的HTML发送URL从，然后该网页把这段代码，你会得到电子邮件响应上

<?php 
error_reporting(E_ALL^E_NOTICE); 
$email = $_GET['ipn_email']; 
$header = ""; 
$emailtext = ""; 
// Read the post from PayPal and add 'cmd' 
$req = 'cmd=_notify-validate'; 
if(function_exists('get_magic_quotes_gpc'))

    $get_magic_quotes_exits = true; 
} 
foreach ($_POST as $key => $value) 
// Handle escape characters, which depends on setting of magic quotes 
{ 
    if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1){ 
     $value = urlencode(stripslashes($value)); 
    } else {

贝宝的IPN（即时付款通知）测试在他们的开发者网站的工具 - 你可以用它在交易完成后进行回调。那么你可以写一个php脚本来检查付款状态，确认它是成功的，然后做你想做的任何事情...

检查开发人员的沙箱中的文档，看看它是如何工作的，他们给一些与...

你可以使用IPN来模拟结帐请求，但它只会将您的请求发送给您的URL，以便您可以测试您的应用程序。如果你想测试你是否正在收取适量的金钱或类似的东西，你必须改变你用来购买东西的形式。它不应指向paypal.com，而应该指向沙盒网址https://www.sandbox.paypal.com/cgi-bin/webscr

它会觉得你真的在买东西，但你不是，因为你会使用测试账户。购买完成后，您可以前往沙盒，使用测试账户登录，查看一个人如何拥有更少的钱（买方），另一个拥有更多的钱（卖方）。
