查看日志我得到了：

好的..非常一般的错误。但它来自Authorize.net，它告诉我它可以是以下任何一种：
The system-generated void for the original timed-out transaction failed. (The original transaction timed out while waiting for a response from the authorizer.)
The system-generated void for the original errored transaction failed. (The original transaction experienced a database error.)
The system-generated void for the original errored transaction failed. (The original transaction experienced a processing error.)
与response_code，120或121无关，122我得到了什么。
我的问题是，如何找出此交易的response_code是什么？
或者更好的是，还有其他人有这样的调试CC问题的主要方法吗？
