Swift/Stripe error communicating with the Parse Cloud Code - swift

Question

I have been working for days trying to figure out how to charge a card and save the card to a customer with Stripe using Swift, with Parse.com Cloud Code as the backend. I integrated the Stripe pod with my project successfully, and I have a token that is created, and prints out in the console to verify its existence. BUT I cannot do anything with it! I have searched everywhere for answers, and cannot figure out why I keep getting error. I think it has to do with the parameters that I am trying to feed to the Cloud Code, but I am unsure. I have read the docs for both Cloud Code and Stripe, and it was to no avail. This is my 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)
}
}
I have added the "Hello World" example to see if the Cloud Code was set up correctly, and that callFunction does work. My Cloud Code is:
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");
}
});
});
Any help would be truly appreciated!! I have been working tirelessly to figure this out! The console prints out
Uh oh, something went wrong (Code: 141, Version: 1.7.2)

Answer 1

The error you are seeing Uh oh, something went wrong (Code: 141, Version: 1.7.2) means that your createCharge Parse function returned an error. You may want to log the value of httpResponse to find the exact error from Stripe.
Looking at your code the error is most likely: Invalid Request Error: Cannot use token tok_3TnIVhEv9P24T0 more than once. You can confirm this in the Logs section of your Stripe Dashboard.
I see that you print the token, println(tokenId), you're also going to want to send that to your Parse function and set card equal to the value of the token you just created.

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: { (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)
}
}
And My updated cloud code is here:
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");
}
});
});
Ultimately I want to have the create customer in a different viewController.swift file and charge on another section of the app, but for right now I am testing it with them in the same PaymentViewController.swift file
