【问题标题】:Not receiving PayPal IPN callback收不到 PayPal IPN 回调
【发布时间】:2017-12-15 02:55:24
【问题描述】:

这是我的付款表单和成功页面,用于获取付款并将付款数据存储到我的数据库中。 付款表格工作正常,但success.php 页面未从贝宝获取任何数据。我已经在 paypal 帐户中添加了 IPN 和自动返回 url,但它不起作用。请有人帮助我。

<?php
include 'dbConfig.php';

//Get payment information from PayPal
$item_number = $_GET['item_number']; 
$txn_id = $_GET['tx'];
$payment_gross = $_GET['amt'];
$currency_code = $_GET['cc'];
$payment_status = $_GET['st'];

//Get product price from database
$productResult = $db->query("SELECT price FROM products WHERE id = ".$item_number);
$productRow = $productResult->fetch_assoc();
$productPrice = $productRow['price'];

if(!empty($txn_id) && $payment_gross == $productPrice){
	//Check if payment data exists with the same TXN ID.
    $prevPaymentResult = $db->query("SELECT payment_id FROM payments WHERE txn_id = '".$txn_id."'");

    if($prevPaymentResult->num_rows > 0){
        $paymentRow = $prevPaymentResult->fetch_assoc();
        $last_insert_id = $paymentRow['payment_id'];
    }else{
        //Insert tansaction data into the database
        $insert = $db->query("INSERT INTO payments(item_number,txn_id,payment_gross,currency_code,payment_status) VALUES('".$item_number."','".$txn_id."','".$payment_gross."','".$currency_code."','".$payment_status."')");
        $last_insert_id = $db->insert_id;
    }
?>
  <h1>Your payment has been successful.</h1>
  <h1>Your Payment ID -
    <?php echo $last_insert_id; ?>.</h1>
  <?php }else{ ?>
  <h1>Your payment has failed.</h1>
  <?php } ?>

为获得付款而唱歌并且工作正常,但我没有收到 IPN 消息和我的数据库中的任何数据?

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;
<?php
//Include db configuration file
include 'dbConfig.php';

//Set useful variables for paypal form
$paypalURL = 'https://www.sandbox.paypal.com/cgi-bin/webscr'; //Test PayPal API URL
$paypalID = 'mybusiness@demo.com'; //Business Email

    【解决方案1】:

    Brother 使用$_REQUEST 方法而不是$_GET 方法来获取您的交易详情。希望对你有帮助

    【讨论】:

    • 数据可以来自$_GET$_POST,使用$_REQUEST表示你不确定它来自哪里。
    • 是的,你是对的@MatteoTassinari,但我几天前尝试了相同的代码,我遇到了同样的问题,但是当我将 $_request 放在 $_GEt 的位置时,它会正常工作。这就是我给出这个答案的原因。希望它能帮助他摆脱困境。
    • 如果你从$_REQUEST而不是$_GET获取数据,那么数据可能在$_POST
    • 感谢@MatteoTassinari 提供的有用信息。
    【解决方案2】:

    您使用的代码更有可能用于 PDT 功能,而不是用于 IPN。请查看以下页面以获取 IPN 的示例代码。

    此外,您可以查看以下页面以比较这两个功能及其详细信息。
