我有一个使用嵌入式支付处理的自适应支付。一切正常(购买得到处理),但我的 IPN 监听器从未收到通知。我使用了 PayPal 提供的 IPN 测试工具,听众接听电话,但不是来自嵌入付款。
这是在支付密钥中发送的信息:
$bodyparams = array (
"requestEnvelope.errorLanguage" => \"en_US",
"actionType" => "PAY",
"cancelUrl" => "http://mysite.com/cancel",
"returnUrl" => "http://mysite.com/buying",
"currencyCode" => "USD",
"paymentType" => "DIGITALGOODS",
"ipnNotificationUrl" => 'http://mysite.com/listener.php',
"trackingId" => $rows['key'],
"memo" => 'You are buying ' . $title . ' from ' . $paypal . '',
"receiverList.receiver.email" => $paypal,
"receiverList.receiver.amount" => $price
);
这是我的监听器代码(取自 PayPal 网站):
<?php
$req = 'cmd=' . urlencode('_notify-validate');
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.sandbox.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($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_HTTPHEADER, array('Host: https://www.sandbox.paypal.com'));
$res = curl_exec($ch);
curl_close($ch);
$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 = $_POST['payer_email'];
if (strcmp ($res, "VERIFIED") == 0) {
$myFile = "log.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "logged ' . $txn_id . '\n";
fwrite($fh, $stringData);
fclose($fh);
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}
?>
再次,PayPal IPN 测试工具证明监听器有效,但是为什么实际支付没有通知监听器呢?
