无法正确解析JSON使用带有条纹的Firebase

原学程将引见没法准确剖析JSON应用戴有条纹的Firebase的处置办法，这篇学程是从其余处所瞅到的，而后减了1些海外法式员的疑问与解问，愿望能对于您有所赞助，佳了，上面开端进修吧。

成绩描写

毛病是-
线程七：&quot；没法依据协定STPCustomerEphEmeralKeyProvider剖析暂时稀钥呼应。保证您的后端将暂时稀钥的未经修正的JSON收送到您的运用法式。有闭具体信息，请参阅https://stripe.com/docs/mobile/ios/standard#prepare-your-api"

毛病的屏幕截图是-

我的MyAPIClient-

 import Stripe
 import UIKit
class MyAPIClient: NSObject, STPCustomerEphemeralKeyProvider {
let baseURL = URL(string: "https://api.stripe.com")!

 func createCustomerKey(withAPIVersion apiVersion: String, completion: @escaping STPJSONResponseCompletionBlock) {
  let url = self.baseURL.appendingPathComponent("ephemeral_keys")
  var urlComponents = URLComponents(url: url, resolvingAgainstBaseURL: false)!
  urlComponents.queryItems = [URLQueryItem(name: "api_version", value: apiVersion)]
  var request = URLRequest(url: urlComponents.url!)
  request.httpMethod = "POST"
  let task = URLSession.shared.dataTask(with: request, completionHandler: { (data, response, error) in
guard let response = response as? HTTPURLResponse,
 response.statusCode == 二00,
 let data = data,
 let json = ((try? JSONSerialization.jsonObject(with: data, options: []) as? [String : Any]) as [String : Any]??) else {
 completion(nil, error)
 return
}
completion(json, nil)
  })
  task.resume()
 }
}

望图掌握器代码-

import UIKit
import Stripe
import FirebaseFunctions

  class paymentViewController: UIViewController {

@IBOutlet weak var paymentMethodButton: UIButton!
@IBOutlet weak var proceedToCheckoutButton: UIButton!

var paymentContext: STPPaymentContext!

override func viewDidLoad() {
 super.viewDidLoad()
 setupStripeConfig()
}

@IBAction func checkoutButtonClicked(_ sender: Any) {
 paymentContext.requestPayment()
}

@IBAction func paymentMethodClicked(_ sender: Any) {
 print("Payment Method Button Clicked")
 paymentContext.presentPaymentOptionsViewController()
}

func setupStripeConfig() {
 let config = STPPaymentConfiguration.shared()
 config.requiredBillingAddressFields = .none
 config.requiredShippingAddressFields = .none

 let customerContext = STPCustomerContext(keyProvider: MyAPIClient())
 paymentContext = STPPaymentContext(customerContext: customerContext, configuration: config, theme: .default())
 paymentContext.paymentAmount = 一000

 paymentContext.delegate = self
 paymentContext.hostViewController = self
  }
 }

extension paymentViewController: STPPaymentContextDelegate {

  func paymentContextDidChange(_ paymentContext: STPPaymentContext) {
 self.paymentMethodButton.titleLabel?.text = paymentContext.selectedPaymentOption?.label
}


func paymentContext(_ paymentContext: STPPaymentContext, didFailToLoadWithError error: Error) {
 //When stripeID isn't valid or Ephemeral key could not be retrieved for some reason. Handle this with UIAlert stating error and make user re-enter info
 self.navigationController?.popViewController(animated: true)
}

func paymentContext(_ paymentContext: STPPaymentContext, didCreatePaymentResult paymentResult: STPPaymentResult, completion: @escaping STPPaymentStatusBlock) {

 var data = [
  "customer":"Abhishek"
 ]
 //Pull Payment Method
 Functions.functions().httpsCallable("getPaymentMethods").call(data) { (result, err) in
  if err != nil {
print("Error (String(describing: err))")
return
  }

  print(result)
 }


 let idempotency = UUID().uuidString.replacingOccurrences(of: "-", with: "")
  var paymentMethod = paymentContext.selectedPaymentOption

 let dataToSend: [String : Any] = [
  "amount" : 五000,
  "customer" : "Abhishek",
 ]

 Functions.functions().httpsCallable("createPaymentIntent").call(dataToSend) { (result, err) in
  if err != nil {
print("Error (String(describing: err))")
return
  }

 //var paymentParam = STPPaymentIntentParams(clientSecret: result as! String)
  print(result)
 }
}

  func paymentContext(_ paymentContext: STPPaymentContext, didFinishWith status: STPPaymentStatus, error: Error?) {

}

  }

怎样整顿？

推举谜底

创立暂时稀钥的要求必需在办事器端收回(应用稀钥)，而且您的iOS代码应当向您本身的办事器收回要求，该办事器将挪用Stiped的API。

如今，您的代码(在MyApiClient中)正在测验考试直交挪用Strike的API去创立暂时稀钥客户端。这没有起感化，假如您记载要求呼应或者检讨仪表板以检查您比来的要求，您能够会瞅到某种毛病新闻。

您应当检查1下Strip的文档，懂得怎样创立暂时稀钥here--它们遍历了一切代码，而且有1个不妨用于尝试的毛刺端面。因为您应用的是Firebase，是以您借不妨检查Havehere的示例。
