PayPal IPN验证握手但IPN无效

标签： php curl paypal paypal-ipn paypal-sandbox

我在使用“旧”PayPal IPN代码时遇到问题。 当我使用PayPal IPN模拟器时，我收到消息IPN was sent and the handshake was verified.，但在我的日志中，我可以看到IPN消息是Invalid

我已经检查了以下内容：

  • 服务器支持SHA2并具有SHA2 SSL证书
  • 已为商家帐户激活IPN
  • IPN网址正确
  • PayPal按钮语言编码设置为UTF-8

我使用的代码 

        define("DEBUG", true);
        define("USE_SANDBOX", 1);

        $raw_post_data = file_get_contents('php://input');
        $raw_post_array = explode('&', $raw_post_data);
        $myPost = array();

        foreach ($raw_post_array as $keyval) {
            $keyval = explode ('=', $keyval);
            if (count($keyval) == 2)
                $myPost[$keyval[0]] = urldecode($keyval[1]);
        }

        $req = 'cmd=_notify-validate';

        if(function_exists('get_magic_quotes_gpc')) {
            $get_magic_quotes_exists = true;
        }

        foreach ($myPost as $key => $value) {
            if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) {
                $value = urlencode(stripslashes($value));
            } else {
                $value = urlencode($value);
            }
            $req .= "&$key=$value";
        }

2 个答案:

答案 0 :(得分：0)

您提供的代码表明您正在使用Sanbox进行调试。因此，您必须检查Paypal表单操作是否具有sanbox链接，并且您的企业帐户也是sanbox。

如果您想使用实际的PayPal帐户，请将第二行更改为define("USE_SANDBOX", 0);

答案 1 :(得分：0)

最后解决了这个问题。使用PayPal Sandbox时需要注意以下几点：

  • 当您使用 PayPal IPN模拟器时，响应将始终为Invalid。
  • PayPal Sandbox IPN响应可以延迟几分钟（不仅仅是几秒钟），因此请稍等一下，看看是否有响应传入。
  • 由于某些原因，如果PayPal沙盒帐户与真实的PayPal帐户具有完全相同的邮件地址，则PayPal Sandbox不会发送回复。

通过考虑上面指出的事情，我已经解决了我的问题。 希望这也能帮助别人。
