貝寶IPN從貝寶模擬器失敗

Question

我嘗試使用貝寶的沙盒IPN模擬器發送一些測試付款，但仍然IPN日誌說IPN失敗。我試圖進入Profile > Selling Tools > Language Encoding > Changed to UTF-8仍然沒有用。 IPN日誌說

[09/11/2014 10:02 PM] - FAIL: IPN Validation Failed.

IPN Response from Paypal Server: 
HTTP/1.0 302 Found 
Location: https://www.sandbox.paypal.com 
Server: BigIP 
Connection: close 
Content-Length: 0 

按照PayPal的文檔，我去過這個鏈接是PayPal的文檔中提到https://gist.github.com/xcommerce-gists/3440401/download#。並嘗試使用相同的代碼，並在PayPal IPN設置和IPN模擬器的通知URL中設置了網址。但仍然沒有工作。不幸的是，上述鏈接中的代碼不會向日志文件添加任何記錄。

我也有另一個代碼，在日誌文件中記錄，但記錄爲失敗。

代碼：

<?php 
ob_start(); 
if($_SESSION == null) { 
    session_start(); 
} 
error_reporting(0); 
require_once('paypal.class.php'); // include the class file 
$p = new paypal_class;    // initiate an instance of the class 
$p->paypal_url = 'https://www.sandbox.paypal.com/cgi-bin/webscr'; // testing paypal url 
$this_script = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']; 
if (empty($_GET['action'])) $_GET['action'] = 'process'; 

switch ($_GET['action']) { 

    case 'ipn': 

     if ($p->validate_ipn()) { 

    $subject = 'Instant Payment Notification - Recieved Payment'; 
    $p->send_report ($subject); 
     } 
     else { 
    $subject = 'Instant Payment Notification - Payment Fail'; 
    $p->send_report ($subject); 
     } 
     break; 
}  
?>

你卻忘記添加驗證這是我的樣子：

很抱歉的代碼：P
