如何在Windows 10应用中实施应用内购买？ [英] How to Implement In-App Purchases in Windows 10 Apps?

问题描述

我想将应用内购买集成到我的Windows通用应用中。在编码之前，我先做以下事情。

• 在




• 如果不返回任何内容，则很有可能在 WindowsStoreProxy.xml 中出错。我建议您创建自己的 WindowsStoreProxy.xml 并使用 CurrentAppSimulator.ReloadSimulatorAsync 方法读取它，如下所示：

    var文件=等待Windows.ApplicationModel.Package.Current.InstalledLocation.GetFileAsync（@ Testing\WindowsStoreProxy.xml）; 
  等待CurrentAppSimulator.ReloadSimulatorAsync（file）; 
    




• 对我来说，使用 C：\Users中的默认值user<用户名> \AppData\Local\Packages\<应用程序包文件夹> \LocalState\Microsoft\Windows Store\ApiData\WindowsStoreProxy.xml
  不起作用，但是一个简单的更改已经解决了问题：我更改了此部分

   < LicenseInformation> 
  < App> 
  < IsActive> true< / IsActive> 
  < IsTrial> true< / IsTrial> 
  < / App> 
  < / LicenseInformation> 
    

  到此：

   <许可证信息> 
  < App> 
  < IsActive> true< / IsActive> 
  < IsTrial> false< / IsTrial> 
  < / App> 
  < / LicenseInformation> 
    

  （因此 IsTrial 设置为false。 ..）




• 现在我也想提一下，这有点奇怪，因为默认情况下是 WindowsStoreProxy.xml 没有为我的应用内购买定义产品。因此，对于我的 RemoveAds，正确的 WindowsStoreProxy.xml 如下所示：

   <？xml version = 1.0 encoding = utf-16吗？ 
  < CurrentApp> 
  < ListingInformation> 
  < App> 
  < AppId> 00000000-0000-0000-0000-000000000000< / AppId> 
  < LinkUri> http：//apps.microsoft.com/webpdp/app/00000000-0000-0000-0000-000000000000< / LinkUri> 
  < CurrentMarket> zh-CN< / CurrentMarket> 
  < AgeRating> 3< / AgeRating> 
  < MarketData xml：lang = zh-CN> 
  < Name> AppName< / Name> 
  < Description> AppDescription< / Description> 
  < Price> 1.00< / Price> 
  < CurrencySymbol> $< / CurrencySymbol> 
  < CurrencyCode> USD< / CurrencyCode> 
  < / MarketData> 
  < / App> 
  < Product ProductId = RemoveAds LicenseDuration = 1 ProductType = Durable> 
  < MarketData xml：lang = zh-CN> 
  < Name> RemoveAds< / Name> 
  < Price> 1.00< / Price> 
  < CurrencySymbol> $< / CurrencySymbol> 
  < CurrencyCode> USD< / CurrencyCode> 
  < / MarketData> 
  < / Product> 
  < / ListingInformation> 
  < LicenseInformation> 
  < App> 
  < IsActive> true< / IsActive> 
  < IsTrial> false< / IsTrial> 
  < / App> 
  < Product ProductId = 1> 
  < IsActive> true< / IsActive> 
  < / Product> 
  < / LicenseInformation> 
  < ConsumableInformation> 
  <产品ProductId = RemoveAds TransactionId = 10000000-0000-0000-0000-000000000000 Status =有效 /> 
  < / ConsumableInformation> 
  < / CurrentApp> 
    




• 我要指出的另一件事是 CurrentAppSimulator具有两个参数的.RequestProductPurchaseAsync 已过时。省略true参数，您将得到 PurchaseResults 实例作为结果，该实例包含 ReceiptXML 属性中的收据。

I want to integrate in-app purchasing in my windows universal app. I do the following thing before coding.

• Make App on Windows Dev Center

• Add products with details in IAPs section and submit to Store as you can see in Image

• After that I use the following code in my app to get list of products of In-App purchasing and button to purchase product. I also used CurrentApp instead of CurrentAppSimulator in my code but it goes in exception.

private async void RenderStoreItems()
    {
        picItems.Clear();

        try
        {
            //StoreManager mySM = new StoreManager();
            ListingInformation li = await CurrentAppSimulator.LoadListingInformationAsync();

            System.Diagnostics.Debug.WriteLine(li);

            foreach (string key in li.ProductListings.Keys)
            {
                ProductListing pListing = li.ProductListings[key];
                System.Diagnostics.Debug.WriteLine(key);

                string status = CurrentAppSimulator.LicenseInformation.ProductLicenses[key].IsActive ? "Purchased" : pListing.FormattedPrice;

                string imageLink = string.Empty;

                picItems.Add(
                    new ProductItem
                    {
                        imgLink = key.Equals("BaazarMagzine101") ? "block-ads.png" : "block-ads.png",
                        Name = pListing.Name,
                        Status = status,
                        key = key,
                        BuyNowButtonVisible = CurrentAppSimulator.LicenseInformation.ProductLicenses[key].IsActive ? false : true
                    }
                );
            }

            pics.ItemsSource = picItems;
        }
        catch (Exception e)
        {
            System.Diagnostics.Debug.WriteLine(e.ToString());
        }
    }

    private async void ButtonBuyNow_Clicked(object sender, RoutedEventArgs e)
    {
        Button btn = sender as Button;

        string key = btn.Tag.ToString();

        if (!CurrentAppSimulator.LicenseInformation.ProductLicenses[key].IsActive)
        {
            ListingInformation li = await CurrentAppSimulator.LoadListingInformationAsync();
            string pID = li.ProductListings[key].ProductId;

            string receipt = await CurrentAppSimulator.RequestProductPurchaseAsync(pID, true);

            System.Diagnostics.Debug.WriteLine(receipt);

            // RenderStoreItems();
        }
    }

I also Associate my app with Store and my app package is same as in MS Dev Center App as you can see in Image

When I run my app and click on Buy button, I got this dialogue box as you can see in Image after that I did not get receipt data from Store.

If I'm doing wrong then Please give me proper guide to implement the In-app purchase and test that In-app purchase in my laptop device.

解决方案

I also had this issue and the problem was in the WindowsStoreProxy.xml file.

Solution in short

By default in the WindowsStoreProxy.xml the IsTrial is set to true and in that mode in-app purchases do not seem to work. When I changed it to false it started to work for me.

Solution a little bit longer

• So first of all here we are talking about the simulation of an In-App Purchase in development time (by using the CurrentAppSimulator class). In that case you need a WindowsStoreProxy.xml file. It’s described here

• Now the window you showed is opened by the CurrentAppSimulator.RequestProductPurchaseAsync line. It basically controls the return value of a Windows Runtime native method (which is very strange for me… I think it’s not intentional by Microsoft… something else should be done there), but if you let it return S_OK that basically is the case when the user paid for the in-App Purchase.

• When it returns nothing then with very high probability something in the WindowsStoreProxy.xml is wrong. I suggest you to create your own WindowsStoreProxy.xml and read it with the CurrentAppSimulator.ReloadSimulatorAsync method like this:

  var file = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFileAsync(@"Testing\WindowsStoreProxy.xml");
  await CurrentAppSimulator.ReloadSimulatorAsync(file);
  

• For me using the default one from C:\Users\<username>\AppData\Local\Packages\<app package folder>\LocalState\Microsoft\Windows Store\ApiData\WindowsStoreProxy.xml did not work, but a single change already solved the problem: I changed this part

  <LicenseInformation>
          <App>
              <IsActive>true</IsActive>
              <IsTrial>true</IsTrial>
          </App>
  </LicenseInformation>
  

  To this:

  <LicenseInformation>
          <App>
              <IsActive>true</IsActive>
              <IsTrial>false</IsTrial>
          </App>
  </LicenseInformation>
  

  (So IsTrial was set to false...)

• Now at this point I also would like to mention that this was a little bit strange, since in in the default WindowsStoreProxy.xml there was no Product defined for my In-App Purchase. So for my "RemoveAds" a proper WindowsStoreProxy.xml would be something like this:

  <?xml version="1.0" encoding="utf-16" ?>
  <CurrentApp>
      <ListingInformation>
          <App>
              <AppId>00000000-0000-0000-0000-000000000000</AppId>
              <LinkUri>http://apps.microsoft.com/webpdp/app/00000000-0000-0000-0000-000000000000</LinkUri>
              <CurrentMarket>en-US</CurrentMarket>
              <AgeRating>3</AgeRating>
              <MarketData xml:lang="en-US">
                  <Name>AppName</Name>
                  <Description>AppDescription</Description>
                  <Price>1.00</Price>
                  <CurrencySymbol>$</CurrencySymbol>
                  <CurrencyCode>USD</CurrencyCode>
              </MarketData>
          </App>
          <Product ProductId="RemoveAds" LicenseDuration="1" ProductType="Durable">
              <MarketData xml:lang="en-US">
                  <Name>RemoveAds</Name>
                  <Price>1.00</Price>
                  <CurrencySymbol>$</CurrencySymbol>
                  <CurrencyCode>USD</CurrencyCode>
              </MarketData>
          </Product>      
      </ListingInformation>
      <LicenseInformation>
          <App>
              <IsActive>true</IsActive>
              <IsTrial>false</IsTrial>
          </App>
          <Product ProductId="1">
              <IsActive>true</IsActive>
          </Product>
      </LicenseInformation>
      <ConsumableInformation>
          <Product ProductId="RemoveAds" TransactionId="10000000-0000-0000-0000-000000000000" Status="Active" />
      </ConsumableInformation>
  </CurrentApp>
  

• Another thing I would like to point out is that the CurrentAppSimulator.RequestProductPurchaseAsync with two parameter is obsolete. Leave the true parameter out and you get PurchaseResults instance as the result, which contains the receipt in the ReceiptXML property.
