result.credit_card_verification即使在braintree错误时也返回零 [英] result.credit_card_verification is returning nil even on error in braintree

问题描述

我正在使用braintree进行付款处理，并且试图获取处理器响应代码（来自Braintree和Ruby）。

I'm using braintree for payment processing and I'm trying to get Processor Response Codes from Braintree with Ruby.

这是我的代码：

 verification = result.credit_card_verification
 response_code = verification.try(:processor_response_code)

即使在

还有其他获取处理器响应代码的东西吗？

Is there something else to get Processor Response Codes?

这里是我的result.erros：

推荐答案

_{我在Braintree工作。如果您想要获得比堆栈溢出更多的帮助，请联系我们的支持团队。}

处理 Braintree结果对象是渐进的。

如果 result.success？是 false ，然后检查 result.errors ，它们表示验证错误。

If result.success? is false, then you check for result.errors, which represent validation errors.

如果 result.errors 是 nil ，则请求有效。在这种情况下，您将拥有交易或验证对象，就像 result.success ？是 true 。

If result.errors is nil, then the request was valid. In this case, you will have a transaction or verification object just as if result.success? was true.

然后您可以查看 result.verification 的状态， processor_response_code ， gateway_rejection_reason 等。

You can then look at the result.verification's status, processor_response_code, gateway_rejection_reason, etc.
