stripe-payments - 如何防止客户添加同一张信用卡

Question

我正在使用Stripe作为我的付款提供商，并将加密的信用卡ID存储在Stripe返回的数据库中。

我的问题是，来自GUI客户可以再次添加同一张卡。我看到条纹不会阻止为同一位客户多次添加同一张卡。由于Stripe总是为同一张卡生成不同的加密卡ID，因此我无法使用它来验证是否再次添加了同一张卡。

如何才能阻止客户再次添加同一张卡。

Answer 1

看来我明白了。我可以使用json响应中返回的指纹。我看到了条纹仪表板，发现对于我再次添加的同一张卡，指纹始终是相同的。

这是json请求和响应以进行确认
