【中文标题】无论我做啥,PayPal IPN 都会不断返回“无效”代码【英文标题】:PayPal IPN Constantly Returning 'INVALID' Code, no matter what I do无论我做什么,PayPal IPN 都会不断返回“无效”代码 【发布时间】:2016-10-30 04:30:09 【问题描述】:我知道这个问题已被多次问过,但是查看所有解决方案,似乎没有一个对我有用。 我一直在使用 PayPal 网站上的 IPN 模拟器将订阅集成到我的网站中,但 IPN 总是返回无效。 我已经尝试了多种方法来使其正常工作,但这是我目前的方法:
<?php

fclose($fp);
private function getPaypalHost()

public function getPostUri()

public function requirePostMethod()
// require POST requests
if ($_SERVER['REQUEST_METHOD'] && $_SERVER['REQUEST_METHOD'] != 'POST')
header('Allow: POST', true, 405);

然后是 Payment.php 类,这是 PayPal 发送请求的地方。
/*The Database Connection Code Is Here*/
include('ipnlistener.php');
$listener = new IpnListener();
$listener->use_sandbox = true;
//$listener->use_curl = false;
try
$verified = $listener->processIpn();
catch (Exception $e)
file_put_contents("paymentdev.php", $e->getMessage()." ".date("H:i"));
//file_put_contents("paymentdev.php", "fudge");
exit(0);
if ($verified)
file_put_contents("paymentdev.php", "test");
$data = $_POST;
$user_id = json_decode($data['custom'])->user_id;
$subscription = ($data['mc_gross_1'] == '49.95') ? 2 : 1;
$txn_id = $data['txn_id'];
$user_id = $user_id;
$paypal_id = $data['subsc_id'];
$subscription = $subscription;
$expires = date('Y-m-d H:i:s', strtotime('+1 Month'));
$sql = "SELECT * FROM payments WHERE user_id=$user_id";
$payment = $mysqli->query($sql);
if(isset($payment) && $payment->num_rows > 0)
$sql = "DELETE FROM payments WHERE user_id=$user_id";
$delete = $mysqli->query($sql);
$sql = "INSERT INTO payments (txn_id, user_id, paypal_id, expires, subscription) VALUES ('$txn_id', $user_id, '$paypal_id', '$expires', $subscription)";
$insertpayment = $mysqli->query($sql);
file_put_contents("paymentdev.php", $mysqli->error);
else
file_put_contents("paymentdev.php", "Transaction not verified ".date("H:i")."<br>".$listener->getTextReport());
echo "Error: Transaction not verified";
提前感谢大家的帮助!
【问题讨论】:
你尝试过的多种方式是什么? @MasterDJon 我尝试使用他们在开发者网站和 GitHub 页面上提供的代码,但都无济于事。它们都与此代码相似,但是我不明白为什么它不起作用 你能提供你所有的信息吗?作为,这个网站/GitHub。任何可以帮助像我这样的人帮助你的东西。你越清楚,你得到答案的速度就越快。 @MasterDJon PayPal 开发者链接是 developer.paypal.com/docs/classic/ipn/ht_ipn,他们在这里链接到他们的 GitHub:github.com/paypal/ipn-code-samples/blob/master/paypal_ipn.php 我也尝试过他们建议在这里做的事情developer.paypal.com/docs/classic/ipn/gs_IPN 首先,使用 PayPal 网站示例从头开始进行测试。没有修改,或者最小的,然后告诉我这是否有效。 【参考方案1】:事实证明我使用的代码很好,我对服务器进行了更多更新,以确保它使用最新的 cURL 并打开 ssl,但即使如此,沙箱也会始终返回 INVALID。我尝试了订阅价格为 0.01 美元的实时版本,付款成功,有效并且我的数据库已更新
IPN 模拟器/沙盒一定很奇怪
