Question

大家好，我运行在使用 PayPal IPN 时遇到了一些麻烦。看来 PayPal 确实到达了我的 PHP 听众并获得了 200 return，并且一旦 t运行saction 完成，我就 returned 到我的网站并获得了肯定消息，我的 t运行saction 已成功，但该帐户未记入购买的商品。我几乎碰壁了，我不确定可能是什么问题。我使用的是过时的命令吗？似乎有什么异常？感谢您的宝贵时间！

<?php

对于PayPal收到200的情况，IPN发送成功，需要调试代码。将每个步骤记录到文件中，使用模拟器或沙盒模式事务测试 IPN（检查 test_ipn=1，使用它来确定是否 post 回到“沙盒”端点，然后不要如果测试 IPN 未验证，则不会中断 - 只需记录它） - 因此使用您的日志输出，找出挂起的位置，直至成功处理您的业务逻辑。
