貝寶IPN驗證問題

我遇到了一些問題，我的貝寶IPN腳本：貝寶IPN驗證問題

$req = 'cmd=_notify-validate'; 

    foreach ($_POST as $key => $value) { 
     $value = urlencode(stripslashes($value)); 
     $req .= "&$key=$value"; 
    } 

    // post back to PayPal system to validate 
    $header = ''; 
    $header = "POST /cgi-bin/webscr HTTP/1.1\r\n";    
    $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; 
    $header .= "Host: www.paypal.com\r\n"; 
    $header .= "Connection: close\r\n"; 
    $header .= "Content-Length: " . strlen($req) . "\r\n\r\n"; 

    $fp = fsockopen('ssl://www.paypal.com', 443, $errno, $errstr, 30); 

    if (!$fp) { 
    // HTTP ERROR 
    } 
    else { 
     fputs ($fp, $header . $req); 
     $response = ''; 
     while (!feof($fp)) { 
      $res = fgets ($fp, 1024); 
      $res = trim($res); 
      if (strpos($res,'VERIFIED') !== false) { 

      } 
      else { 
       // not verified 
      } 
     } 
    }

if (strpos($res,'VERIFIED') !== false)永遠是假的。這是$res回報：

幾個可能的事情，根據關我使用工作的例子...

您可能會運行到序列化問題。
您正在重新發布到ssl：//www.paypal.com而不是https://www.paypal.com/cgi-bin/webscr

您的檢查方式可能有問題嗎？我的例子使用的strcmp()代替strpos()

// read raw POST data to prevent serialization issues w/ $_POST 
$raw_post_data = file_get_contents('php://input'); 
$raw_post_array = explode('&', $raw_post_data); 
$myPost = array(); 
foreach ($raw_post_array as $keyval) { 
    $keyval = explode ('=', $keyval); 
    if (count($keyval) == 2) 
     $myPost[$keyval[0]] = urldecode($keyval[1]); 
} 

// read the post from PayPal system and add 'cmd' 
$req = 'cmd=_notify-validate'; 
foreach ($myPost as $key => $value) { 
    if (get_magic_quotes_gpc()) { 
     $value = urlencode(stripslashes($value)); 
    } else { 
     $value = urlencode($value); 
    } 
    $req .= "&$key=$value"; 
} 

// Post IPN back to PayPal to validate the IPN data is genuine 
$paypal_url = 'https://www.paypal.com/cgi-bin/webscr'; 

$ch = curl_init($paypal_url); 
if ($ch == false) { 
    return false; 
} 

curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $req); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); 
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1); 

// Set TCP timeout to 30 seconds 
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close')); 

// CONFIG: Please download 'cacert.pem' from "http://curl.haxx.se/docs/caextract.html" and set the directory path 
// of the certificate as shown below. Ensure the file is readable by the webserver. 
// This is mandatory for some environments. 
// $cert = __DIR__ . "./cacert.pem"; 
// curl_setopt($ch, CURLOPT_CAINFO, $cert); 

$res = curl_exec($ch); 
curl_close($ch); 

// Inspect IPN validation result and act accordingly 
if (strcmp($res, "VERIFIED") == 0) { 
    // good to go... 
}
