Question

我以前在此应用程序中一直使用字符串，但是后端开发人员完成了所有工作，但是现在更改了其实现并使用SCA支持欧洲支付更改（支持3D安全身份验证），因此现在我需要在本地添加库代码，但我停留在这个地方。

我从服务器获取了客户端ID，但是处理下一步操作将给我类似这样的错误。

Error Domain = STPPaymentHandlerErrorDomain代码= 1“发生意外错误-请在几秒钟后重试。” UserInfo = {com.stripe.lib：ErrorMessageKey =在使用STPPaymentHandler之前，PaymentIntent需要附加PaymentMethod或Source。，NSLocalizedDescription =发生意外错误-请在几秒钟后重试}

我没有找到任何相关文档here

这是我的代码

//Api called on server for client id

Answer 1

我的解决方法是致电paymentManager.confirmPayment(withParams: params, authenticationContext: self)而不是handleNextAction

Stripe SCA需要处理下一步操作
