APP调用Stripe的SDK示例说明

  Stripe.setDefaultPublishableKey(publicKey) 

     let cardParams = cardTextField.cardParams
     let paymentMethodParams = STPPaymentMethodParams(card: cardParams, billingDetails: nil, metadata: nil)

 let paymentIntentParams = STPPaymentIntentParams(clientSecret: clientSecret)
 paymentIntentParams.paymentMethodParams = paymentMethodParams

// Submit the payment
let paymentHandler = STPPaymentHandler.shared()
paymentHandler.confirmPayment(withParams: paymentIntentParams, authenticationContext: self) { [weak self] (status, paymentIntent, error) in
//返回支付结果，根据结果执行后续流程
}
