Paypal IPN 已验证但未更新数据库

Question

我正在使用 paypal IPN 沙盒在收到付款后更新我的数据库中的表格。基于我的 ipn 日志，它显示 OK 和 Verified。这是我的 ipn。我也无法从我的 IPN 接收电子邮件。

我建议您将代码分解成更容易调试和修复的部分。

由于您使用的是 PayPal IPN，因此您应该首先测试是否正确接收并验证了 IPN 响应。

如果您的记录器工作正常，那么首先使用日志文件调试该部分。

如果您发现问题，请修复获取 IPN 数据和验证的部分。

一旦您确定 IPN 的第一部分可以正常工作，您就可以使用此技术更快地继续调试其余代码：

1) 再次测试IPN并使用var_export($_POST, true)
的returns将$_POST的内容写入您的日志文件 2) 打开您的日志文件并检查您是否拥有 IPN 发送给您的完整的 $_POST 数组
3) 复制该数组并将原始 $_POST 数据伪造到脚本中： $_POST = array(..fields from the log..);
4) 现在注释掉执行 IPN 验证的脚本的所有第一部分，只留下伪造的 $_POST
5) 现在您可以通过打开示例手动访问您的脚本，就像您是 PayPal 的 IPN 机器人一样。com/paypal_ipn_script.php

现在您可以继续调试脚本的其余 sql 查询并查看哪个失败了，方法是按 F5 并使用 print_r()、var_dump()、die( ), 等等。所有这一切都无需为每次测试进行新的贝宝付款，从而加快调试过程:)

我在付款时使用 paypal IPN 沙箱来更新数据库中的表格received.Try这段代码从头到尾完整。

    $data = $_POST;
    $url = 'https://www.sandbox.paypal.com/cgi-bin/webscr';
    $data['cmd'] = '_notify-validate';

    $curl = curl_init();
    curl_setopt_array(
        $curl, 
        array(
            CURLOPT_RETURNTRANSFER => 1,
            CURLOPT_FOLLOWLOCATION => 1,
            CURLOPT_POST           => 1,
            CURLOPT_SSL_VERIFYPEER => false,
            CURLOPT_URL            => $url,
            CURLOPT_POSTFIELDS     => $data
        )
    );
    if(!($result = curl_exec($curl))){
        die('Error: "' . curl_error($curl) . '" - Code: ' . curl_errno($curl));
    }
    curl_close($curl);
    if ($result != 'VERIFIED') {

        die('Fraud IPN on Varification.');
    }
        $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'];
          $ctIdcustom       = $_POST['custom'];
