ios - Stripe SCA 需要处理下一步操作

Question

我以前在这个应用程序中使用字符串，但后端开发人员所做的所有事情现在都改变了它们的实现，并通过 SCA 支持欧洲支付变更(支持 3D 安全身份验证)，所以现在我需要在我的本地添加库代码，但我停留在这个地方。

我从服务器获得了客户端 ID，但处理下一个操作会给我类似这样的错误。

Error Domain=STPPaymentHandlerErrorDomain Code=1 "There was an unexpected error -- try again in a few seconds" UserInfo={com.stripe.lib:ErrorMessageKey=The PaymentIntent requires a PaymentMethod or Source to be attached before using STPPaymentHandler., NSLocalizedDescription=There was an unexpected error -- try again in a few seconds}

这是我的代码

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