我已经工作了好几天，试图弄清楚如何使用Swift将卡片收费并使用Stripe将卡片保存给客户，并将Parse.com Cloud Code作为后端。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其存在。但我不能用它做任何事情！我到处寻找答案，无法弄清楚为什么我会一直收到错误。我认为这与我试图提供给Cloud Code的参数有关，但我不确定。我已阅读Cloud Code和Stripe的文档，但无济于事。这是我的PaymentViewController.swift：
list::insert我添加了“Hello World”示例，以查看Cloud Code是否设置正确，以及callFunction是否正常工作。我的Cloud Code是：
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)
}
}
真正感谢任何帮助！我一直在不知疲倦地努力解决这个问题！控制台打印出来
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");
}
});
});
答案 0 :(得分：0)
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 Dashboard的Logs部分确认这一点。
我看到您打印令牌println(tokenId)，您还想要将其发送到您的Parse功能并将卡设置为您刚刚创建的令牌的值。

class PaymentViewController: UIViewController, PTKViewDelegate {
@IBOutlet weak var saveBtn: UIButton!
var paymentView: PTKView = PTKView()
override func 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: { (token: STPToken?, error: NSError?) -> Void in
if (error != nil) {
println(error)
println("not working")
} else {
//println(tokenId)
var coin = token!.tokenId
PFCloud.callFunctionInBackground("hello", withParameters: nil) {
(response: AnyObject?, error: NSError?) -> Void in
let responseString = response as? String
println(responseString)
}
var name = PFUser.currentUser()?.username as String!
var customer = PFUser.currentUser()?.objectId as String!
PFCloud.callFunctionInBackground("createCustomer", withParameters: ["coin" : coin, "name": name, "customer": customer], block: { (success: AnyObject?, error: NSError?) -> Void in
if error != nil {
println("create customer not working")
}
})
var customerId = customer!
PFCloud.callFunctionInBackground("createCharge", withParameters: ["customerId" : customerId], block: { (success: AnyObject?, error: NSError?) -> Void in
if error != nil {
println("not working")
}
})
}
})
}
@IBAction func cancel(sender: AnyObject) {
self.dismissViewControllerAnimated(true, completion: nil)
}
}
我的更新云代码在这里：
var Stripe = require('stripe');
Stripe.initialize('sk_test_xxxxxxxxxxxxxx');
Parse.Cloud.define("hello", function(request, response) {
response.success("Hello world!");
});
Parse.Cloud.define("createCustomer", function(request, response) {
Stripe.Customers.create({
card: request.params.coin,
account_balance: -10*100,
metadata: {
name: request.params.name,
customer: request.params.customer, // e.g PFUser object ID
}
}, {
success: function(customer) {
response.success(customer.id);
},
error: function(error) {
response.error("Error:" +error);
}
})
});
Parse.Cloud.define("createCharge", function(request, response) {
Stripe.Charges.create({
amount: 100 * 10, // $10 expressed in cents
currency: "usd",
//card: request.params.coin
customer: request.params.customerId
},{
success: function(httpResponse) {
response.success("Purchase made!");
},
error: function(httpResponse) {
response.error(httpResponse)
response.error("Uh oh, something went wrong");
}
});
});
最终我希望将创建客户放在另一个viewController.swift文件中并在应用程序的另一部分收费，但是现在我正在使用它们在同一个PaymentViewController.swift文件中对它进行测试
