还原IAP时无法获得完整收据

Question

[当我尝试还原IAP ARS时。我有多个已还原的交易，但是我尝试将当前的收据发送到

public func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
        for transaction in transactions {
            switch (transaction.transactionState) {
            case .purchased:
                complete(transaction: transaction)
                break
            case .failed:
                fail(transaction: transaction)
                break
            case .restored:

                if(transactions.last == transaction) {
                    restoreAndSendToServer(transaction: transaction) } else {
                    restore(transaction: transaction)
                }
                break
            case .deferred:
                break
            case .purchasing:
                break
            }
        }
    }

restoreAndSendToServer的示例

  guard let productIdentifier = transaction.original?.payment.productIdentifier else { return }
         print("restored last... \(productIdentifier)")
         self.sendTokenAndReceptForValidationFirstTime()
         productPurchaseCompleted(identifier: productIdentifier)
         SKPaymentQueue.default().finishTransaction(transaction)

如果将收据数据发送到服务器，则不必处理交易的restore状态。需要验证收据时，只需将收据数据提交到服务器即可。

并且如果设备上不存在收据数据，则无需致电SKPaymentQueue.default().restoreCompletedTransactions()。您应该调用SKReceiptRefreshRequest刷新收据。
