Question

我想一遍又一遍地买同样的物品，但是当试图第二次买时，代码给我空指针异常。

这是代码;

session_start();
if (isset($_GET['hash']) && isset($_SESSION['hash']) &&
    $_GET['hash'] == $_SESSION['hash']) {
    header("Content-type: image/jpeg");
    echo file_get_contents('your hidden image.jpg');
}

当此代码脚本再次运行时，pendinIntent将为null。

如果用户已购买上述代码

，我们可以要求谷歌

try {
        Bundle buyIntentBundle = mService.getBuyIntent(3, getPackageName(), "ucret", "inapp", "bGoa+V7g/yqDXvKRqq+JTFn4uQZbPiQJo4pf9RzJ");

        PendingIntent pendingIntent = buyIntentBundle.getParcelable("BUY_INTENT");

        startIntentSenderForResult(pendingIntent.getIntentSender(), 1001, new Intent(), Integer.valueOf(0), Integer.valueOf(0), Integer.valueOf(0));

    } catch (RemoteException e) {
        e.printStackTrace();
    } catch (IntentSender.SendIntentException e) {
        e.printStackTrace();
    }

但是每当我打开屏幕时，我都想卖掉同样的物品。

感谢您的帮助。

Google阻止用户购买相同的商品。所以，如果你这样做，你必须告诉谷歌＆＃34;让我＆＃34;。这被命名为＃34;消费＆＃34;。

这是所有消费方法

private void consumeBilling() {

    try {

        Bundle ownedItems = iInAppBillingService.getPurchases(3, getPackageName(), "inapp", null);

        int response = ownedItems.getInt("RESPONSE_CODE");

        if (response == 0) {

            ArrayList<String> ownedSkus = ownedItems.getStringArrayList("INAPP_PURCHASE_ITEM_LIST");

            ArrayList<String> purchaseDataList = ownedItems.getStringArrayList("INAPP_PURCHASE_DATA_LIST");

            ArrayList<String> signatureList = ownedItems.getStringArrayList("INAPP_DATA_SIGNATURE_LIST");

            String continuationToken = ownedItems.getString("INAPP_CONTINUATION_TOKEN");

            for (int i = 0; i < purchaseDataList.size(); ++i) {

                String purchaseData = purchaseDataList.get(i);

                //   String signature = signatureList.get(i);

                //    String sku = ownedSkus.get(i);

                //    RDALogger.info("purchaseData " + purchaseData + " signature " + signature + " sku " + sku);

                RDALogger.info("purchaseData " + purchaseData);

                String purchaseTokenString = new JSONObject(purchaseData).getString("purchaseToken");

                int responsee = iInAppBillingService.consumePurchase(3, getPackageName(), purchaseTokenString);

                RDALogger.info("Consuming response " + responsee);
            }
        }

    } catch (Exception e) {

        e.printStackTrace();

        ErrorHandlers.handle(PaymentActivity.this, new HoustonWeGotAProblemException());
    }
}

来自purchaseData的PurschaseToken将转到此代码

  int responsee = iInAppBillingService.consumePurchase(3, getPackageName(), purchaseTokenString);

之后你告诉谷歌，这个项目可以再次购买。
