UWP addOnLicense.IsActive始终为true

问题描述

我尝试了各种技术，但是即使用户，也无法弄清楚为什么此代码总是会导致有效（有效？）许可证。还没有购买该应用程序附件。

该功能在应用启动时初始化。

public async void GetLicenseInfo()
{
    if (context == null)
    {
        context = StoreContext.GetDefault();
        // If your app is a desktop app that uses the Desktop Bridge,you
        // may need additional code to configure the StoreContext object.
        // For more info,see https://aka.ms/storecontext-for-desktop.
    }

    workingProgressRing.IsActive = true;
    StoreAppLicense appLicense = await context.GetAppLicenseAsync();
    workingProgressRing.IsActive = false;

    if (appLicense == null)
    {
        messagetextblock.Text = "An error occurred while retrieving the license.";
        return;
    }

    // Use members of the appLicense object to access license info...

    // the customer can' t access this feature
    messagetextblock.Text = "customer hasn't bought the addon";

    // Access the valid licenses for durable add-ons for this app.
    foreach (keyvaluePair<string,StoreLicense> item in appLicense.AddOnLicenses)
    {
        StoreLicense addOnLicense = item.Value;
        // Use members of the addOnLicense object to access license info
        // for the add-on.

        // Specify the kinds of add-ons to retrieve.
        string[] productKinds = { "Durable","Consumable","UnmanagedConsumable" };
        List<String> filterList = new List<string>(productKinds);
        StoreProductQueryResult queryResult = await context.GetAssociatedStoreProductsAsync(filterList);

        if (addOnLicense.IsActive)
        {
            // the customer can access this feature
            messagetextblock.Text = "customer has bought the addon";
        }
    }
    
}

解决方法

很难确切地说明上述示例出了什么问题。但是，我在市场上有一个使用两种不同类型的应用程序内购买的应用程序。一个删除广告，另一个获得高级许可。

您执行操作与执行操作之间的区别是，我正在随许可证一起返回的许可证书中查找订阅商店ID。

您尝试过这种方法吗？

        public static void CheckForPremiumStatus()
        {
#if DEBUG
            if (LicenseInformation.ProductLicenses["PremiumStatus"].IsActive)
            {
                IsPremium = RemoveAds = true;
            }
#else
            var subscriptionStoreId = "9PMT47KC5W6C";

            foreach (var addOnLicense in _appLicense.AddOnLicenses)
            {
                StoreLicense license = addOnLicense.Value;
                if (license.SkuStoreId.StartsWith(subscriptionStoreId))
                {
                    if (license.IsActive)
                    {
                        IsPremium = RemoveAds = true;
                        return;
                    }
                    else
                    {
                        break;
                    }
                }
            }

            IsPremium = RemoveAds = false;
#endif
        }
