PayPal IPN不做任何事

Question

我希望有人能夠解釋我過去兩天一直在想的問題。我已閱讀並重新閱讀PayPal文檔，並且不提供任何幫助或見解。

這是IPN監聽器我用，這是示例腳本貝寶提供：

<?php 
// CONFIG: Enable debug mode. This means we'll log requests into 'ipn.log' in the same directory. 
// Especially useful if you encounter network errors or other intermittent problems with IPN (validation). 
// Set this to 0 once you go live or don't require logging. 
define("DEBUG", 1); 
// Set to 0 once you're ready to go live 
define("USE_SANDBOX", 1); 
define("LOG_FILE", "./ipn.log"); 
// Read POST data 
// reading posted data directly from $_POST causes serialization 
// issues with array data in POST. Reading raw POST data from input stream instead. 
$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'; 
if(function_exists('get_magic_quotes_gpc')) { 
    $get_magic_quotes_exists = true; 
} 
foreach ($myPost as $key => $value) { 
    if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) { 
     $value = urlencode(stripslashes($value)); 
    } else { 
     $value = urlencode($value); 
    } 
    $req .= "&$key=$value"; 
} 
// Post IPN data back to PayPal to validate the IPN data is genuine 
// Without this step anyone can fake IPN data 
if(USE_SANDBOX == true) { 
    $paypal_url = "https://www.sandbox.paypal.com/cgi-bin/webscr"; 
} else { 
    $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); 
if(DEBUG == true) { 
    curl_setopt($ch, CURLOPT_HEADER, 1); 
    curl_setopt($ch, CURLINFO_HEADER_OUT, 1); 
} 
// CONFIG: Optional proxy configuration 
//curl_setopt($ch, CURLOPT_PROXY, $proxy); 
//curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 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); 
if (curl_errno($ch) != 0) // cURL error 
    { 
    if(DEBUG == true) { 
     error_log(date('[Y-m-d H:i e] '). "Can't connect to PayPal to validate IPN message: " . curl_error($ch) . PHP_EOL, 3, LOG_FILE); 
    } 
    curl_close($ch); 
    exit; 
} else { 
     // Log the entire HTTP response if debug is switched on. 
     if(DEBUG == true) { 
      error_log(date('[Y-m-d H:i e] '). "HTTP request of validation request:". curl_getinfo($ch, CURLINFO_HEADER_OUT) ." for IPN payload: $req" . PHP_EOL, 3, LOG_FILE); 
      error_log(date('[Y-m-d H:i e] '). "HTTP response of validation request: $res" . PHP_EOL, 3, LOG_FILE); 
     } 
     curl_close($ch); 
} 
// Inspect IPN validation result and act accordingly 
// Split response headers and payload, a better way for strcmp 
$tokens = explode("\r\n\r\n", trim($res)); 
$res = trim(end($tokens)); 
if (strcmp ($res, "VERIFIED") == 0) { 
    // check whether the payment_status is Completed 
    // check that txn_id has not been previously processed 
    // check that receiver_email is your PayPal email 
    // check that payment_amount/payment_currency are correct 
    // process payment and mark item as paid. 
    // assign posted variables to local variables 
    //$item_name = $_POST['item_name']; 
    //$item_number = $_POST['item_number']; 
    $payment_status = $_POST['payment_status']; 
    //$payment_amount = $_POST['mc_gross']; 
    //$payment_currency = $_POST['mc_currency']; 
    //$txn_id = $_POST['txn_id']; 
    //$receiver_email = $_POST['receiver_email']; 
    //$payer_email = $_POST['payer_email']; 

    if ($payment_status == 'Completed') { 
    include_once('update.php');  
    } 

    if(DEBUG == true) { 
     error_log(date('[Y-m-d H:i e] '). "Verified IPN: $req ". PHP_EOL, 3, LOG_FILE); 
    } 
} else if (strcmp ($res, "INVALID") == 0) { 
    // log for manual investigation 
    // Add business logic here which deals with invalid IPN messages 
    if(DEBUG == true) { 
     error_log(date('[Y-m-d H:i e] '). "Invalid IPN: $req" . PHP_EOL, 3, LOG_FILE); 
    } 
} 
?> 

我缺少什麼？我想要做的是驗證付款是否完成，然後從另一個文件中包含PHP。沙箱帳戶中的IPN歷史記錄顯示IPN請求正在發送並且正在接收HTTP 200響應。

payment_status也肯定會發送，因爲它也顯示在IPN歷史記錄中。

任何幫助或指向一些真正有意義的IPN教程的指針將受到大力讚賞！

謝謝大家！

固定！

PayPal要求使用cacert.pem文件進行SSL /簽名連接。你可以通過改變

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);

關閉這個功能要

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 

感謝您的幫助傢伙！
