详细描述

Transaction contains information about a transaction in the external app store and is usually provided as a result of calling purchase() on a product. When the purchase flow has ended, whether it's successful or not, either the product's onPurchaseSucceeded or onPurchaseFailed handler will be called with a transaction object as argument.

Transaction cannot be created directly in QML, but is only provided as an argument to the purchase handlers in the products.

方法文档编制

void finalize ()

Call this when the application has finished performing all necessary reactions to the purchase. If the purchase succeeded, the application should store the information about the transaction in a safe way before finalizing it. All transactions should be finalized.
