Paypal IPN PHP腳本沒有插入數據庫

我讀了一些答案試圖解決我的問題，但沒有奏效。下面的代碼是從https://github.com/Quixotix/PHP-PayPal-IPN Paypal IPN PHP腳本沒有插入數據庫

我已經這樣做：

集IPN的URL在貝寶（不是localhost）;
刪除「完成」條件;
刪除「txn_id」等條件試圖使其工作;

這些嘗試都不適用於我，即使我使用ipn模擬器。

<?php 

// tell PHP to log errors to ipn_errors.log in this directory 
ini_set('log_errors', true); 
ini_set('error_log', dirname(__FILE__).'/ipn_errors.log'); 

    // intantiate the IPN listener 
include('PHP-PayPal-IPN-master/ipnlistener.php'); 
$listener = new IpnListener(); 

// tell the IPN listener to use the PayPal test sandbox 
$listener->use_sandbox = true; 

    // try to process the IPN POST 
try { 
    $listener->requirePostMethod(); 
    $verified = $listener->processIpn(); 
} catch (Exception $e) { 
    error_log($e->getMessage()); 
    exit(0); 
} 

if ($verified) { 

$errmsg = ' <br/>'; // stores errors from fraud checks 

// 1. Make sure the payment status is "Completed" 
if ($_POST['payment_status'] != 'Completed') { 
    //simply ignore any IPN that is not completed 
    exit(0); 
} 

// 2. Make sure seller email matches your primary account email. 
if ($_POST['receiver_email'] != '[email protected]') { 
    $errmsg .= "'receiver_email' does not match: "; 
    $errmsg .= $_POST['receiver_email']."\n"; 
} 

// 3. Make sure the amount(s) paid match 
if ($_POST['mc_gross'] != '10') { 
    $errmsg .= "'mc_gross' does not match: "; 
    $errmsg .= $_POST['mc_gross']."\n"; 
} 


// 4. Make sure the currency code matches 
if ($_POST['mc_currency'] != 'USD') { 
    $errmsg .= "'mc_currency' does not match: "; 
    $errmsg .= $_POST['mc_currency']."\n"; 
} 

// 5. Ensure the transaction is not a duplicate. 
include_once("../includes/psl-config.php"); 
$mysqli = new mysqli(HOST, USER, PASSWORD, DATABASE); 

$txn_id = mysqli_real_escape_string($mysqli, $_POST['txn_id']); 
$sql = "SELECT COUNT(*) FROM paypal WHERE txn_id = '$txn_id'"; 
$r = mysqli_query($mysqli, $sql); 

if (!$r) { 
    error_log(mysqli_error($mysqli)); 
    exit(0); 
} 

$exists = $r; 

if ($exists) { 
    $errmsg .= "'txn_id' has already been processed: ".$_POST['txn_id']."\n"; 
} */ 

if (!empty($errmsg)) { 

    // manually investigate errors from the fraud checking 
    $body = "IPN failed fraud checks: \n$errmsg\n\n"; 
    $body .= $listener->getTextReport(); 
    mail('[email protected]', 'IPN Fraud Warning', $body); 

} else { 

    // add this order to a table of completed orders 
    if (isset($_POST['item_number'])) { 
     $item_number = $_POST['item_number']; 
    } 

if($stmt = $mysqli->prepare("INSERT INTO paypal (item_number) VALUES (?)")){ 
      $stmt->bind_param('s', $item_number); 
      $stmt->execute(); 
     }else{ 
      $errmsg .= "Error trying to insert into DB<br/>"; 
      error_log(mysqli_error($mysqli)); 
     }        

    // free user ads here 
} 

} else { 
    // manually investigate the invalid IPN 
    mail('[email protected]', 'Invalid IPN', $listener->getTextReport()); 
} 

?>

我一直在收到欺詐電子郵件。有時它給我帶來了txn_id已經被處理了，但是如果沒有任何東西被插入到數據庫中，它如何檢查呢？

你爲什麼不嘗試獲得IPN的RAW POST，然後看看你的評價（S）是/是「失敗」還是「落空」。 – EdSF

好像你會收到詐騙電子郵件時，該腳本返回無效的IPN驗證，

$verified = $listener->processIpn();

當它貼回PayPal來自究竟持平它被送到

IPN驗證只會把你的服務器，除了真實欺詐案件或惡意篡改數據外，語言編碼很可能會輕易導致PayPal與您的網站之間的IPN數據出現差異，從而最終導致INVALID結果。

最佳做法是，您可能需要檢查PayPal帳戶編碼設置並將其設置爲UTF-8，以確保所有類型的字符都能正確格式化並避免驗證失敗。
