问题描述
错误是- 线程7："；无法根据协议STPCustomerEphEmeralKeyProvider分析临时密钥响应。确保您的后端将临时密钥的未经修改的JSON发送到您的应用程序。有关详细信息，请参阅https://stripe.com/docs/mobile/ios/standard#prepare-your-api" 错误的屏幕截图是- 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 == 200,
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()
}
}
视图控制器代码-
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 = 1000
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" : 5000,
"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?) {
}
}
如何整理？
推荐答案
创建临时密钥的请求必须在服务器端发出(使用密钥)，并且您的iOS代码应该向您自己的服务器发出请求，该服务器将调用Stiped的API。
现在，您的代码(在MyApiClient中)正在尝试直接调用Strike的API来创建临时密钥客户端。这不起作用，如果您记录请求响应或检查仪表板以查看您最近的请求，您可能会看到某种错误消息。
您应该查看一下Strip的文档，了解如何创建临时密钥here--它们遍历了所有代码，并且有一个可以用于测试的毛刺端点。由于您使用的是Firebase，因此您还可以查看Havehere的示例。
