iOS- In应用程序购买在沙箱环境中正常工作，Appstore版本内容未解锁

Question

在应用程序内购买工作在沙箱环境中，但在应用程序商店版本金额从用户帐户借记，但内容未解锁。

我不认为在编码方面有问题。否则，它将无法在沙箱环境中工作。我认为有可能交易收据为零。

当我再次点击购买时，它显示“您已经订阅”。但是，它仍然没有解锁应用程序的内容。即使我点击恢复购买，但它也不起作用。我很惊讶为什么一切都能在沙箱环境中工作。

订阅类型:自动续费。内容解锁:音频、视频和pdf教程。

我已经检查了后端日志。API从未执行过，我填写的唯一问题是，即使用户成功购买，我也没有收到应用程序商店的收据。一切都能在沙箱环境中完美工作。

代码：

public func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {

        for transaction in transactions {

            switch transaction.transactionState {
            case .purchasing:
                handlePurchasingState(for: transaction, in: queue)
            case .purchased:
                handlePurchasedState(for: transaction, in: queue)
            case .restored:
                handleRestoredState(for: transaction, queue: queue)
            case .failed:
                handleFailedState(for: transaction, in: queue)
            case .deferred:
                handleDeferredState(for: transaction, in: queue)
            }
        }
    }

//On transaction state changed to purchased:
func handlePurchasedState(for transaction: SKPaymentTransaction, in queue: SKPaymentQueue) {
        print("User purchased product id: \(transaction.payment.productIdentifier)")
        print("User purchased product id: \(transaction)")
        queue.finishTransaction(transaction)
        self.completeTransaction(transaction:transaction)
    }

//In completeTransaction Method:
func completeTransaction(transaction:SKPaymentTransaction)
    {
        if let receiptURL = Bundle.main.appStoreReceiptURL,FileManager.default.fileExists(atPath: receiptURL.path)
        {
            let receipt:Data = try! Data(contentsOf: receiptURL)
            let jsonObjectString = receipt.base64EncodedString(options: Data.Base64EncodingOptions(rawValue: 0))
            var strIdentifier:String = transaction.transactionIdentifier!

            if let identifier = transaction.original?.transactionIdentifier
            {
                strIdentifier = identifier
            }

        //API call to save receipt to validate later and unlock the content
        //In case API calling failed then I stored data and called API again on app home page.
        }
    }

请在验证收款queue.finishTransaction(交易)后完成交易

苹果还建议“在完成交易之前下载所有苹果托管的内容。交易完成后，其下载对象将不能再被使用。”
