从昨天开始，PayPal IPN 就可以正常工作，但今天我收不到任何 IPN。我检查了 MySQL，检查了 IPN 地址，一切都很好。我在想 PayPal 在他们的 IPN 服务器上做了一些改变，电话里的那个女人告诉我没有。有点奇怪。
那么有人可以检查 ipn.php 和 add.php 吗？
添加 php
<?
define('BASEPATH', true);
require_once("../../config.php");
if(!$is_online){
redirect('../../../index.php');
exit;
}
$s_host = parse_url($site['site_url']);
if($_GET['cash'] != '' && is_numeric($_GET['cash'])){
$cash = ($_GET['cash'] < 1 ? 1 : $_GET['cash']);
$cash = number_format($cash, 2, '.', '');
}else{
redirect('../../../index.php');
exit;
}
?>

最佳答案
我遇到了同样的问题。他们开始在响应的末尾添加“\r\n”，所以我将“VERIFIED”与“VERIFIED\r\n”进行比较，但失败了。你可以这样做:
修剪($res)
在测试 VERIFIED 之前，或者您可以使用 strpos 而不是 strcmp:
if (strpos($res, "VERIFIED") === 0)(需要 ===，而不是 ==)
最后，他们还要求所有客户前一段时间开始添加 Connection header :
$header .= "连接:关闭\r\n";
