我的處理程序和貝寶已經溝通了幾天，然後發生了一些事情，使後者停止發送IPN了。我嘗試通過我自己的腳本模擬IPN發送，而無需使用cURL進行驗證的回發功能。我的處理程序非常完美。我還在發回PayPal的行之前放置了一行簡單的代碼（已通過cURL測試過），以便我可以檢查PayPal的響應。該行代碼只是將IPN記錄到數據庫中。它也沒有記錄。它應該是對的？因爲paypal發送兩次IPN。我確保IPN在我的商戶帳戶中打開，鏈接指向我的處理程序。現在我開始懷疑貝寶沒有給我任何東西。這是我的處理器：沙盤PayPal怎麼不送我IPN？
<?php
require_once 'classes/Mysql.php';
require_once 'classes/Email.php';
$mysql = new Mysql();
$myemail = new Email();
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// assign posted variables to local variables
$item_name = $_POST['item_name'];
$payment_status = $_POST['txn_type'];
$payment_amount = $_POST['mc_amount3'];
$payment_currency = $_POST['mc_currency'];
$subscr_id = $_POST['subscr_id'];
$receiver_email = urldecode($_POST['receiver_email']);
$payer_email = $_POST['payer_email'];
$subscr_type = $_POST['option_selection1'];
$username = $_POST['custom'];
//Save a copy of $req to the database. If paypal sends IPN, this should at least grab the first one before validation.
$memberID = $mysql->get_member_id($username);
$mysql->test_message($req.$payment_amount.$payment_currency, $memberID, $username, $payment_amount, $payment_currency);
// post back to PayPal system to validate
$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.paypal.com', 443, $errno, $errstr, 30);
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
//This if block does the payment processing. If I place this before the validation/post back occurs, it doesn't work either. But it works when testing using my cURL script--- before the validation.
if($memberID)
{
if($payment_status=='subscr_signup' && $payment_currency=='USD' && !$mysql->check_if_transactionID_exists($subscr_id))
{
$mysql->activate_subscription($memberID, $subscr_id, $subscr_type, $payment_amount);
}
}
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}
}
fclose ($fp);
}
我聽到很多故事paypal是如此令人沮喪的設置。難道貝寶只是不發送IPN，或者我的處理程序有問題嗎？
