在应用商店中验证应用内购买的收据

Question

我使用以下函数来验证收据。如您所见，我使用了沙盒 URL，因为我在将接收对象提交到商店之前对其进行了测试。我想学习的是：在提交之前，我应该在storeUrl部分写什么？如何访问或找到该 URL？根据我的研究，我需要输入我的服务器地址或其他东西，但我想提交的产品是非消耗品，所以我没有任何服务器。

func verifyReciept (transaction : SKPaymentTransaction?) {
        let recieptURL = Bundle.main.appStoreReceiptURL!
        if let reciept = NSData(contentsOf: recieptURL){
            let requestContents = ["receipt-data" : reciept.base64EncodedString(options: NSData.Base64EncodingOptions(rawValue:0))]
            do {
                let requestData = try JSONSerialization.data(withJSONObject: requestContents, options: JSONSerialization.WritingOptions(rawValue : 0))
                let storeURL = NSURL(string: "https:/sandbox.itunes.apple.com/verifyReceipt")
                let request = NSMutableURLRequest(url: storeURL! as URL)
                request.httpMethod = "Post"
                request.httpBody = requestData
               let session = URLSession.shared
                let task = session.dataTask(with: request as URLRequest, completionHandler: { (responseData: Data?, response : URLResponse?, error : Error?) -> Void in
                do {
                let json = try JSONSerialization.jsonObject(with: responseData!, options: .mutableLeaves) as! NSDictionary
                    print(json)
                    if(json.object(forKey: "status") as! NSNumber) == 0 {
                        let receipt_dict = json["receipt"] as! NSDictionary
                        if let purchases = receipt_dict["in_app"] as? NSArray {
                            self.validatePurchaseArray(purchases: purchases)
                        }
                        if transaction != nil {
                            SKPaymentQueue.default().finishTransaction(transaction!)
                        }
                    }
                    else {
                    print(json.object(forKey: "status") as! NSNumber)
                    }
                }
                catch{
                    print(error)
                    }
               })
                task.resume()
            } catch {
                print(error)
            }
        }
        else {
            print("No Reciept")
        }
    }

Answer 1

您应该将其替换为用于验证收据的产品 URL：

"https://buy.itunes.apple.com/verifyReceipt"

您正在谈论的涉及服务器的事情是您可以采取的额外措施。对于服务器端验证，您需要将收据发送到服务器，然后从服务器运行相同的功能。
