与 Parse Cloud 代码通信的 Swift/Stripe 错误

Question

我已经工作了好几天，试图弄清楚如何使用 Swift 以 Parse.com Cloud Code 作为后端来对卡进行收费并将卡保存给客户。我成功地将 Stripe pod 与我的项目集成，并且我创建了一个令牌，并在控制台中打印出来以验证它的存在。但我不能用它做任何事情！我到处寻找答案，但无法弄清楚为什么我不断出错。我认为这与我试图提供给 Cloud Code 的参数有关，但我不确定。我已经阅读了 Cloud Code 和 Stripe 的文档，但无济于事。这是我的 PaymentViewController.swift：

import UIKit
import Stripe
import PaymentKit
import Parse
import Bolts




class PaymentViewController: UIViewController, PTKViewDelegate {


@IBOutlet weak var saveBtn: UIButton!

var paymentView: PTKView = PTKView()

override func viewDidLoad() {
    super.viewDidLoad()



    var view : PTKView = PTKView(frame: CGRectMake(15,20,290,55))

    paymentView = view
    paymentView.delegate = self;
    self.view.addSubview(self.paymentView)

    saveBtn.enabled = false



}

func paymentView(view: PTKView!, withCard card: PTKCard!, isValid valid: Bool) {
    if (valid) {
        saveBtn.enabled = true
    } else {
        saveBtn.enabled = false
    }
}



override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}





@IBAction func save(sender: AnyObject) {

    var card: STPCard = STPCard()
    card.number = self.paymentView.card.number
    card.expMonth = self.paymentView.card.expMonth
    card.expYear = self.paymentView.card.expYear
    card.cvc = self.paymentView.card.cvc

    STPAPIClient.sharedClient().createTokenWithCard(card, completion: { (tokenId: STPToken?, error: NSError?) -> Void in
        if (error != nil) {
            println(error)
            println("what the..")
        } else {
            println(tokenId)


            PFCloud.callFunctionInBackground("hello", withParameters: nil) {
                (response: AnyObject?, error: NSError?) -> Void in
                let responseString = response as? String
                println(responseString)
            }




            PFCloud.callFunctionInBackground("createCharge", withParameters: nil, block: { (success: AnyObject?, error: NSError?) -> Void in
                if error != nil {
                    println("error")
                }
            })








        }
    })



}







@IBAction func cancel(sender: AnyObject) {
    self.dismissViewControllerAnimated(true, completion: nil)
}






}

我添加了“Hello World”示例以查看云代码是否设置正确，以及 callFunction 是否有效。我的云代码是：

var Stripe = require('stripe');
Stripe.initialize('My_Secret_Key');

Parse.Cloud.define("hello", function(request, response) {
               response.success("Hello world!");
               });

Parse.Cloud.define("createCharge", function(request, response) {
               Stripe.Charges.create({
                                     amount: 100 * 10, // $10 expressed in cents
                                     currency: "usd",
                                     card: "tok_3TnIVhEv9P24T0"
                                     },{
                                     success: function(httpResponse) {
                                     response.success("Purchase made!");
                                     },
                                     error: function(httpResponse) {
                                     response.error("Uh oh, something went wrong");
                                     }
                                     });


               });

任何帮助将不胜感激！我一直在不知疲倦地解决这个问题！控制台打印出来

Uh oh, something went wrong (Code: 141, Version: 1.7.2)

                                                          metadata: {

                                                          }

                                                         }, {

                                     //card: request.params.coin
                                     customer: request.params.customerId

                                     response.success("Purchase made!");
                                     },
                                     error: function(httpResponse) {
                                     response.error(httpResponse)
                                     response.error("Uh oh, something went wrong");
                                     }
                                     });


               });

最终我希望在不同的 viewController.swift 文件中创建客户并在应用程序的另一部分收费，但现在我正在同一个 PaymentViewController.swift 文件中与他们一起测试它

您看到的错误Uh oh, something went wrong (Code: 141, Version: 1.7.2) 表示您的 createCharge Parse 函数返回了错误。您可能需要记录 httpResponse 的值以从 Stripe 中找到确切的错误。

查看您的代码最有可能出现错误：Invalid Request Error: Cannot use token tok_3TnIVhEv9P24T0 more than once。您可以在 Stripe 仪表板的日志部分确认这一点。

我看到您打印了令牌println(tokenId)，您还希望将其发送到您的 Parse 函数并将卡设置为等于您刚刚创建的令牌的值。
