应用内订阅

Question

当我使用测试帐户在应用程序中测试订阅时，它会返回成功回调，并且根据回调我将一些信息存储在我的远程服务器上......但是当我发布它并使用其他帐户测试时订阅已扣除并且执行成功，但我无法收到成功回调，因为我无法访问内容。我们如何从购买模型或库存模型中获取交易信息，而不是我们如何获取有关特定订单 ID 的信息，例如剩余时间等，这些信息由谷歌自行管理。我们如何在每台设备上识别用户和（他/她）订阅以访问内容

您可以在 QueryInventoryFinishedListener 中获取购买详细信息，如

Purchase monthlySubscription = inv.getPurchase(SKU_SUBSCRIPTION_MONTHLY);

        if (monthlySubscription != null) {
            Log.d(TAG, "User has already subscribed for monthly benefits.");
            Utils.Log(monthlySubscription.toString());

        } else {
            launchSubscriptions();
        }



private void launchSubscriptions() {
    try {
        iabHelper.launchSubscriptionPurchaseFlow((Activity) context, 
        SKU_SUBSCRIPTION_MONTHLY, REQUEST_CODE, new 
        IabHelper.OnIabPurchaseFinishedListener() {
            @Override
            public void onIabPurchaseFinished(IabResult result, 
            Purchase monthlySubscription) throws 
            IabHelper.IabAsyncInProgressException {
                if (result.isFailure()) {
                    Log.e(TAG, "Error purchasing: " + result);
                } else if (result.isSuccess()) {
                    Log.d(TAG, "---Success---");
                } else {
                    Log.d(TAG, "---Error---");
                }
            }
        }, String.valueOf(preferences.getUserId()));
    } catch (IabHelper.IabAsyncInProgressException e) {
        e.printStackTrace();
    }
}

您还在“launchSubscriptionPurchaseFlow”方法中添加了一个额外的参数。每当您获得购买详细信息时，您也会获得该额外参数。所以使用这个参数你可以识别用户明智的购买 （在我的例子中，我在 launchSubscriptions() 方法中添加了 userId）
