PayPal IPN 已验证，但未更新数据库

Question

收到付款时PayPal我正在使用IPN沙箱更新数据库中的表。基于我的ipn日志，它显示正常和已验证。这是我的ipn。此外，我无法从我的 IPN 接收电子邮件。

Answer 1

我建议你将代码分解为可以更容易调试和修复的部分。

由于您PayPal使用的是 IPN，因此应首先测试是否正确接收和验证了 IPN 响应。

如果您的记录器工作正常，则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。

确定 IPN 的第一部分正常工作后，可以使用以下技术继续更快地调试其余代码：

1） 再次测试 IPN，并使用 var_export($_POST, true)
的返回将 $_POST 的内容写入日志文件2）打开您的日志文件并检查您是否拥有IPN发送给您的
完整的$ _POST数组3） 复制该数组并将原始的 $_POST 数据伪造到脚本中：$_POST = array（..日志中的字段..）;
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
美元5）现在，您可以通过打开 example.com/paypal_ipn_script.php 来手动访问脚本，就好像您是PayPal的IPN机器人一样

现在，您可以继续调试脚本的其余 sql 查询，并通过按 F5 并使用 print_r（）、var_dump（）、die（） 等来查看哪个查询失败。所有这些都无需为每个测试支付新的PayPal费用，从而加快调试过程:)

收到付款时PayPal我正在使用 IPN 沙箱更新数据库中的表。从头到尾完整尝试此代码。

    $data = $_POST;
