Apple Pay and Stripe：令牌未被发送到Stripe

Question

在我的应用中设置Apple Pay，在设备上运行时似乎运行正常。使用Stripe作为支付处理器，但它没有将令牌发送到Stripe，但似乎正在通过iPhone的数字钱包中列出的信用卡收费。

我遇到的问题是，一旦我按下“使用触摸ID付款”，我的Apple Pay表中会出现一个复选标记，但Xcode中会出现以下页面：

Apple Pay＆amp;的代码条纹

    var paymentSucceeded: Bool = false


func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController,
                                        didAuthorizePayment payment: PKPayment, completion: @escaping (PKPaymentAuthorizationStatus) -> Void) {

    STPAPIClient.shared().createToken(with: payment) { (token, error) in
        print("I am here")

            if error != nil {
                completion(.failure)
                print("failed")

            } else {

func postStripeToken(token: STPToken) {

    let URL = "http://localhost/donate/payment.php"
    let params = ["stripeToken": token.tokenId,
                  "amount": Int(self.driverInfoView.rydeFare.text!)!,
                  "currency": "cad",

    let manager = AFHTTPSessionManager()
    manager.post(URL, parameters: params, success: { (operation, responseObject) -> Void in

        if let response = responseObject as? [String: String] {

            let alertController = UIAlertController(title: response["status"], message: response["message"], preferredStyle: .alert)

            let defaultAction = UIAlertAction(title: "OK", style: .default, handler: nil)
            alertController.addAction(defaultAction)

            self.present(alertController, animated: true, completion: nil)

    }) { (operation, error) -> Void in
        self.handleError(error as NSError)
        print(error)
    }
}

我将非常感谢您如何解决此问题。

启用异常断点，然后Xcode应该在导致问题的行上崩溃。

几乎可以肯定是由您的代码中的!之一引起的。

强制展开值非常危险。在guard let或if let中展开它总是更好，更安全。
