函数 callDoDirectPayment() 处的 Magento 付款失败

Question

我在使用 Paypal Payments Pro 在 Magento 1.6.1 上调试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”。

我已尝试检查错误日志，并将结果发布在下面。第一次使用这个系统和更多的前端开发，但我正在设法跟随 php。

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？调查这个过程的下一步应该是什么明智的？任何额外的 paypal / magento 特定知识都非常受欢迎！

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 - 快速网关有效）- 我将如何确认或反驳这个假设？

谢谢

Answer 1

您是否在 Magento 的 PayPal 设置中启用了调试功能？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，这将帮助您找出究竟出了什么问题。
