我正在尝试在网站上集成 PayPal IPN。由于某种原因,IPN 侦听器既没有验证付款也没有将其标记为无效。我mail()
在代码的不同点放置了函数,以通知我正在运行多少程序。
我尝试过使用和不使用trim()
变量$res
。两种方式都失败了。
这是我的代码:
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
mail('test@test.net', 0, 0); //EMAIL RECEIVED
$header = "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
$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'];
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$address_street = $_POST['address_street'];
$address_city = $_POST['address_city'];
$address_zip = $_POST['address_zip'];
$address_state = $_POST['address_state'];
$address_country = $_POST['address_country'];
$contact_phone = $_POST['contact_phone'];
$payer_id = $_POST['payer_id'];
if (!$fp) {
//HTTP Error
mail('test@test.net', 1, 1);
} else {
fputs ($fp, $header . $req);
mail('test@test.net', 2, 2); //EMAIL RECEIVED
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp (trim($res), "VERIFIED") == 0) {
mail('test@test.net', 3, 3);
} else if (strcmp (trim($res), "INVALID") == 0) {
mail('test@test.net', 4, 4);
} else {
mail('test@test.net', 5, 5); //EMAIL RECEIVED
}
}
fclose ($fp);
}
}
我收到的电子邮件是 0、2 和 5。
