如何在iOS中使用Braintree实施付款应用 [英] How to implement a payment app with Braintree in iOS

问题描述

我的问题是:我创建了一个应该接受信用卡/借记卡的应用程序.我在iOS中使用Braintree 4 SDK在可可豆荚中快速使用.我可以很好地呈现该下降，但是这样做只是问一个抄送号，然后消失了，为什么?因为我使用了快速入门指南中的代码，所以应该这样做.但这并没有说明何时调用nonce函数或显示金额或任何内容！使用SDK 3是一个视图控制器，我可以在其中放置委托，除了记住卡片，几乎所有东西都可以使用.所以我的问题是我应该在iOS的哪里调用nonce函数?总数应显示在哪里?以及如何向服务器BT付款?

My issue is this: I have created an app that is supposed to accept Credit/Debit cards. And Im using Braintree 4 SDK in iOS with swift using a cocoa pod. I can present the drop in just fine but what it does is that just ask for a cc number and then disappears, why? Because I use the code in the quick-start guide and it's supposed to do that. But it doesn't say anything about when to call the nonce function or show the amount or anything! With SDK 3 is a view controller where I can put the delegate and almost everything works except remembering cards. So my question are where am I supposed to call the nonce function in iOS? Where does the total should be shown? And how do I make a payment to the server BT?.

我的代码:

// Mark - Braintree methods

    func showDropIn(clientTokenOrTokenizationKey: String) {

            let request =  BTDropInRequest()
            request.amount = "\(total)"
            request.currencyCode = "MXN"
//            request.
            let dropIn = BTDropInController(authorization: clientTokenOrTokenizationKey, request: request)
            { (controller, result, error) in
                if (error != nil) {
                    print("ERROR")
                } else if (result?.isCancelled == true) {
                    print("CANCELLED")
                } else if let result = result {
                    // Use the BTDropInResult properties to update your UI
                    // result.paymentOptionType
                    // result.paymentMethod
                    // result.paymentIcon
                    // result.paymentDescription
                    print(result)

//                    controller.
                }
                controller.dismiss(animated: true, completion: nil)
            }
            self.present(dropIn!, animated: true, completion: nil)

//        //create paymentrequest
//        let
//        paymentRequest: BTPaymentRequest = BTPaymentRequest()
//        paymentRequest.summaryTitle = "Lavado Automozo"
//        paymentRequest.summaryDescription = "$\(totalLabel.text!) precio total de los servicios solicitados."
//        paymentRequest.displayAmount = "$\(total!).00 MXN"
//        paymentRequest.currencyCode = "MXN"
//        paymentRequest.callToActionText = "Aceptar compra."
//        paymentRequest.shouldHideCallToAction = false
//        //set delegate
//        let dropInViewController = BTDropInViewController(apiClient: braintreeClient!)
//        dropInViewController.delegate = self
//        dropInViewController.paymentRequest = paymentRequest
//        //add cancel button
//        dropInViewController.navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.cancel, target: self, action: #selector(ViewController.userDidCancelPayment))
//        
//        //present view
//        let navigationController = UINavigationController(rootViewController: dropInViewController)
//        
//        present(navigationController, animated: true, completion: nil)
//        
        //        let request =  BTDropInRequest()
//        let dropIn = BTDropInController()
//        { (controller, result, error) in
//            if (error != nil) {
//                print("ERROR")
//            } else if (result?.isCancelled == true) {
//                print("CANCELLED")
//            } else if let result = result {
//                // Use the BTDropInResult properties to update your UI
//                // result.paymentOptionType
//                // result.paymentMethod
//                // result.paymentIcon
//                // result.paymentDescription
//            }
//            controller.dismiss(animated: true, completion: nil)
//        }
//        self.present(dropIn!, animated: true, completion: nil)
    }

我应该在哪里称呼它?:

And Where am I supposed to call this?:

func postNonceToServer(paymentMethodNonce: String) -> Bool {

        PFCloud.callFunction(inBackground: "checkout", withParameters: ["payment_method_nonce" : paymentMethodNonce, "amount" : "\(total!).00"]) {

            (response, error) -> Void in

            //            let ratings = response as? Float
            // ratings is 4.5

            if error != nil {


            } else {


            }

            print("the response \(response ?? "nil")")
            print("The error: \(error?.localizedDescription)")

虚拟卡关闭后，它会自动关闭.

After the dummy card it just closes.

推荐答案

_{完整披露:我在Braintree工作.如有其他疑问，请随时与支持.}

您可以通过showDropIn()中的result对象访问付款方式随机数.您也可以在这里调用 postNonceToServer() .

You can access the payment method nonce via the result object within showDropIn(). This is also where you may call postNonceToServer().

func showDropIn(clientTokenOrTokenizationKey: String) {
    let request =  BTDropInRequest()
    request.amount = "\(total)"
    request.currencyCode = "MXN"
    let dropIn = BTDropInController(authorization: clientTokenOrTokenizationKey, request: request)
    { (controller, result, error) in
        if (error != nil) {
            print("ERROR")
        } else if (result?.isCancelled == true) {
            print("CANCELLED")
        } else if let result = result {
            let selectedPaymentMethod = result.paymentMethod! // retrieve the payment method.
            self.postNonceToServer(paymentMethodNonce: selectedPaymentMethod.nonce) // call postNonceToServer() with the nonce from the selected payment method.
        }
        controller.dismiss(animated: true, completion: nil)
    }
    self.present(dropIn!, animated: true, completion: nil)
}

成功致电postNonceToServer()后，您可以接收付款方式随机数并

After you successfully call postNonceToServer() you can receive the payment method nonce and create a transaction on your server.
