php - 函数 callDoDirectPayment() 的 Magento 支付失败

Question

我在使用 Paypal Payments Pro 调试 Magento 1.6.1 上的支付网关时遇到问题。它一直失败并显示消息“处理您的订单时出错。”请联系我们或稍后再试。”

我已经尝试检查错误日志，并在下面发布了结果。第一次使用这个系统和更多的前端开发人员，但我设法跟上了 php.ini 的步伐。

它似乎失败的关键行是

    $this->_importFromResponse($this->_doDirectPaymentResponse, $response);

有人能准确解释一下这条线的作用吗？调查此过程的明智下一步应该是什么？欢迎任何额外的 paypal/magento 特定知识!

我猜既然创建了数组，那么转移到 paypal 可能会出现问题(我的 api 签名应该没问题 - 快速网关可以工作)- 我将如何确认或反驳这个假设？

谢谢

Answer 1

您是否在 Magento 的 PayPal 设置中启用了调试？如果是这样，那么您应该会在/var/log 中看到一个日志，这样您就可以看到来回发送的 RAW 请求和响应数据。

这将允许您查看响应中返回的实际错误代码和消息，这将帮助您找出到底出了什么问题。
