貝寶IPN失敗

Question

我已經建立了Paypal帳戶通知URL去這個腳本：

// Read the notification from PayPal which comes in the form of a POST array and create the acknowledgement response 
    $req = 'cmd=_notify-validate';    // add 'cmd' to beginning of the acknowledgement you send back to PayPal 

    foreach ($_POST as $key => $value) 
    { // Loop through the notification NV pairs 
    $value = urlencode(stripslashes($value)); // Encode the values 
    $req .= "&$key=$value";     // Add the NV pairs to the acknowledgement 
    } 


    // Assign the paypal payment notification values to local variables 
    if($_POST){ 
    $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'];} 

    //Set up the acknowledgement request headers (this is the updated version for http 1.1) 
    $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"; 
    //Open a socket for the acknowledgement request 
    $fp = fsockopen ('www.paypal.com', 80, $errno, $errstr, 30); 

    if(!$fp){ 
     echo "HTTP ERROR"; 
    } 
    else 
    {//start 1 

    // Post request back to PayPal for validation 
    fputs ($fp, $header . $req); 

    //once paypal receives the acknowledgement response, another message will be send containing the single word VERIFIED or INVALID 

    while (!feof($fp)) 
     { //start 2, while not EndOfFile 
    $res = fgets ($fp, 1024); // Get the acknowledgement response 
    $res = trim($res); 
     if (strcmp ($res, "VERIFIED") == 0) 
      {// start 3, Response is OK 

      if ($payment_status == "Completed") 
       {//start 4 

       //send email announcing success 

       $from = "Rupert Heath Literary Agency"; 
       $to = $payer_email; 
       $subject = "Ebook"; 
       $body = "It works"; 
       mail($to, $subject, $body, $from); 

       }//end 4 
      }//end 3 
      else if(strcmp ($res, "INVALID") == 0) 
       {//start 5 

       //send email announcing failure 
       //$error_log .= 'Line 57' 

       $from = "Guide Test Page"; 
       $to = $payer_email; 
       $subject = "INVALID IPN"; 
       $body = "Doesn't work"; 
       mail($to, $subject, $body, $from); 
       }//end 5 


    } //end 2 
fclose ($fp); //close file pointer 
} //end 1 

這是基於大量的Web託管的例子，迎合升級到HTTP 1.1

該腳本作爲測試，根據PayPal的VERIFIED或INVALID響應發送成功或失敗電子郵件。問題是我總是收到無效的電子郵件，無法理解原因。我查看了PayPal IPN歷史記錄，HTTP響應代碼是200，似乎表明IPN交換正常工作，因此可能PayPal正在響應驗證，但我的腳本有錯誤。

任何人都可以幫我調試這個問題嗎？

Answer 1

這很可能是這一行的問題。如果你的PHP配置有（上帝幫助你）Magic Quotes，你只需要包含stripslashes。值得慶幸的是，魔術引號已被刪除的PHP 5.4的，所以你可以放心地可能從該行刪除stripslashes，使其：

$value = urlencode($value); 

不管你信不信，貝寶允許用戶數據包含反斜線。因此，如果IPN有任何反斜槓，並且您使用stripslashes刪除它們，當您將IPN數據發回PayPal進行驗證時，Paypal會給您INVALID響應，因爲數據不匹配。

Answer 2

這將是最好使用原始發佈的數據，而不是自己重建它。這是我個人使用的代碼，並至今一直運作良好：

file_get_contents(
    'https://www.paypal.com/cgi-bin/webscr?cmd=_notify-validate', 
    false, 
    stream_context_create(array(
     'http'=>array(
      'method'=>'POST', 
      'header' => 'Content-Type: application/x-www-form-urlencoded', 
      'content' => file_get_contents('php://input'), 
     ) 
    )) 
); 

它可以很容易地變成捲曲爲好。

$value = urlencode(stripslashes($value)); 

具體而言，使用stripslashes有：
