华为In App Purchase沙盒测试，我已经购买过一次的商品无法购买

Question

IAP沙盒测试中，消耗品和非消耗品购买一次后不可再次购买。导致无法显示支付页面。在 onActivityResult 中，IAP SDK returns code

ORDER_PRODUCT_OWNED 60051

这是普遍问题还是我做错了什么？

Answer 1

在沙盒环境中，您可以购买消耗品和非消耗品。购买后，您可以食用它们。之后可以再次购买，方便测试。

调用消费接口消费产品。

Answer 2

60051 表示用户已拥有该产品，因此未能购买该产品。并且@Disavowed 给出了解释和解决方案。 https://developer.huawei.com/consumer/en/doc/development/HMS-References/iap-ExceptionHandlingAndGeneralErrorCodes-v4

这是关于如何使用产品的代码。

/**
 * Consume the unconsumed purchase with type 0 after successfully delivering the product, then the Huawei payment server will update the order status and the user can purchase the product again.
 * @param inAppPurchaseData JSON string that contains purchase order details.
 */
private void consumeOwnedPurchase(final Context context, String inAppPurchaseData) {
    Log.i(TAG, "call consumeOwnedPurchase");
    IapClient mClient = Iap.getIapClient(context);
    Task<ConsumeOwnedPurchaseResult> task = mClient.consumeOwnedPurchase(createConsumeOwnedPurchaseReq(inAppPurchaseData));
    task.addOnSuccessListener(new OnSuccessListener<ConsumeOwnedPurchaseResult>() {
        @Override
        public void onSuccess(ConsumeOwnedPurchaseResult result) {
            // Consume success
            Log.i(TAG, "consumeOwnedPurchase success");
            Toast.makeText(context, "Pay success, and the product has been delivered", Toast.LENGTH_SHORT).show();
        }
    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(Exception e) {
            Log.e(TAG, e.getMessage());
            Toast.makeText(context, e.getMessage(), Toast.LENGTH_SHORT).show();
            if (e instanceof IapApiException) {
                IapApiException apiException = (IapApiException)e;
                Status status = apiException.getStatus();
                int returnCode = apiException.getStatusCode();
                Log.e(TAG, "consumeOwnedPurchase fail,returnCode: " + returnCode);
            } else {
                // Other external errors
            }

        }
    });
}

/**
 * Create a ConsumeOwnedPurchaseReq instance.
 * @param purchaseData JSON string that contains purchase order details.
 * @return ConsumeOwnedPurchaseReq
 */
private ConsumeOwnedPurchaseReq createConsumeOwnedPurchaseReq(String purchaseData) {

    ConsumeOwnedPurchaseReq req = new ConsumeOwnedPurchaseReq();
    // Parse purchaseToken from InAppPurchaseData in JSON format.
    try {
        InAppPurchaseData inAppPurchaseData = new InAppPurchaseData(purchaseData);
        req.setPurchaseToken(inAppPurchaseData.getPurchaseToken());
    } catch (JSONException e) {
        Log.e(TAG, "createConsumeOwnedPurchaseReq JSONExeption");
    }

    return req;
}

Answer 3

错误代码60051表示用户购买产品失败，因为用户已经拥有该产品。

解决方法：使用obtainOwnedPurchasesAPI查询用户是否购买了商品

已购买的消耗品，发货后调用consumeOwnedPurchaseAPI消费商品。消费后，下次可以购买该产品。如果产品是非消耗品或订阅产品，则无法再次购买该产品。

查询所有已购买的应用内商品信息，包括消耗品、非消耗品和自动续订订阅。

如果返回耗材信息，则耗材由于某些例外情况，可能无法交付。在这种情况下，您的应用需要检查耗材是否送达。如果没有，应用程序需要交付它们并调用 consumeOwnedPurchase API 来消耗它们。
如果返回非消耗品信息，非消耗品不需要消耗
如果信息 about subscriptions 被返回，所有现有的订阅返回用户在应用中的关系。
如果 purchaseState 是 0，这意味着产品是 PURCHASED.
如果 purchaseState 是 1 那意味着产品是 CANCELED.
如果 purchaseState 是 2，这意味着产品是 PURCHASED.

代码：

public void checkUserOwnedTheProduct(final Context context) {
        OwnedPurchasesReq ownedPurchasesReq = new OwnedPurchasesReq();
        ownedPurchasesReq.setPriceType(productType);
        Task<OwnedPurchasesResult> task = Iap.getIapClient(context).obtainOwnedPurchases(ownedPurchasesReq);
        task.addOnSuccessListener(new OnSuccessListener<OwnedPurchasesResult>() {
            @Override
            public void onSuccess(OwnedPurchasesResult result) {
                // Obtain the execution result.
                if (result != null && result.getInAppPurchaseDataList() != null) {
                    for (int i = 0; i < result.getInAppPurchaseDataList().size(); i++) {
                        String inAppPurchaseData = result.getInAppPurchaseDataList().get(i);
                        String inAppSignature = result.getInAppSignature().get(i);
                        boolean success = CipherUtil.doCheck(inAppPurchaseData, inAppSignature, Key.getPublicKey());
                        if (success) {
                            try {
                                InAppPurchaseData inAppPurchaseDataBean = new InAppPurchaseData(inAppPurchaseData);
                                int purchaseState = inAppPurchaseDataBean.getPurchaseState();                            

                            } catch (JSONException e) {
                            }
                        }
                    }
                } else {
                    if (productType == IapClient.PriceType.IN_APP_NONCONSUMABLE) {
                        ((HmsInAppPurchaseList) context).loadList();
                        return;
                    }
                }
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(Exception e) {
                if (e instanceof IapApiException) {
                    IapApiException apiException = (IapApiException) e;
                    Status status = apiException.getStatus();
                    int returnCode = apiException.getStatusCode();
                } else {
                    // Other external errors
                }
            }
        });
