如何验证已取消的应用内订阅？

Question

我正在使用：bp.isSubscribed(ID) 来验证我的订阅。但是当我取消订阅时，方法 bp.isSubscribed(ID) 仍然 returning 为真。我该怎么办？

transDetails.purchaseInfo.purchaseData.purchaseState.toString() 在我从 Play 商店管理订阅手动取消后总是 return 购买成功。

public void checkSubscriptionDetails(){

bp = new BillingProcessor(this, LICENSE_KEY, new BillingProcessor.IBillingHandler() {
            @Override
            public void onProductPurchased(@NonNull String productId, @Nullable TransactionDetails details) {

                Common.printLog("InApp", ":onProductPurchased :" + productId);


            }

            @Override
            public void onPurchaseHistoryRestored() {

            }

            @Override
            public void onBillingError(int errorCode, @Nullable Throwable error) {
           }

            @Override
            public void onBillingInitialized() {


            }
        });


boolean purchaseResult = bp.loadOwnedPurchasesFromGoogle();
// ## purchaseResult is always return FALSE 

        if (bp.isSubscribed(planID)) {

            TransactionDetails transDetails = bp.getSubscriptionTransactionDetails(planID);

            String strDetailsSubsMonth = "OrderID:" + transDetails.orderId +
                    "\nproductId: " + transDetails.productId +
                    "\npurchaseToken: " + transDetails.purchaseToken +
                    "\npurchaseTime: " + transDetails.purchaseTime +
                    "\npurchaseInfo.signature: " + transDetails.purchaseInfo.signature +
                    "\npurchaseInfo.responseData: " + transDetails.purchaseInfo.responseData +
                    "\npurchaseData.purchaseToken: " + transDetails.purchaseInfo.purchaseData.purchaseToken +
                    "\npurchaseData.autoRenewing: " + transDetails.purchaseInfo.purchaseData.autoRenewing +
                    "\npurchaseData.developerPayload: " + transDetails.purchaseInfo.purchaseData.developerPayload +
                    "\npurchaseData.purchaseState: " + transDetails.purchaseInfo.purchaseData.purchaseState.toString();

            String strPurchaseState = transDetails.purchaseInfo.purchaseData.purchaseState.toString();
            Common.printLog("InApp", "Details: " + planID + " >> " + strDetailsSubsMonth + " \n" + "Purchase State :" + strPurchaseState);
        }

}


package com.anjlab.android.iab.v3;

public enum PurchaseState
{
    PurchasedSuccessfully,
    Canceled,
    Refunded,
    SubscriptionExpired
}

取消订阅后我需要return"Canceled"。

Answer 1

在onCreate()中启动bp变量，然后调用loadOwnedPurchasesFromGoogle()。

In my case!

不知道为什么要多次调用loadOwnedPurchasesFromGoogle()。当我在 onCreate() 中调用 loadOwnedPurchasesFromGoogle() 时，我总是得到 false。但是当我调用 onPause() 和 onDestory() 时，我得到了 true 并且我的所有值都得到了更新。

得到loadOwnedPurchasesFromGoogle()真后，我得到更新订阅值！

Answer 2

服务器端的最佳解决方案获取订阅的实际信息，或者您可以通过 Node.js 配置进行交叉验证。
