实施Xbox Live服务时出现错误0x87DD0005

问题描述

我刚刚在项目中添加了XBox支持代码，并且遇到了至少两个问题。

第一个涉及到保存数据同步，该同步工作正常，但是当游戏在Windows上读取用户的登录数据时，其行为就像未完成登录一样-角落没有显示gamertag，并且登录提供程序抛出错误0x87DD0005，无论重试次数如何。

在XBox上执行代码就可以了-只有Windows似乎受此影响。最初，我（也至少要等到我准备在ID @ XBox再次进行展示之前）以创作者的展示台为目标，因此，成就和类似目标现在不再是问题。

以下是我正在使用的代码（且无特定顺序）：

public void doStartup()
{
   getData(-1);
   for (int i = 0; i <= 5; i++)
   {
      getData(i);
   }
   ContentViewport.source = new Uri("ms-appx-web:///logo.html");
}

public async void getData(int savefileId)
{
   var users = await Windows.System.User.FindAllAsync();

   string c_saveBlobName = "Advent";
   //string c_saveContainerdisplayName = "GameSave";
   string c_saveContainerName = "file" + savefileId;
   if (savefileId == -1) c_saveContainerName = "config";
   if (savefileId == 0) c_saveContainerName = "global";
   GameSaveProvider gameSaveProvider;

   GameSaveProviderGetResult gameSaveTask = await GameSaveProvider.GetForUserAsync(users[0],"00000000-0000-0000-0000-00006d0be05f");
   //Parameters
   //Windows.System.User user
   //string SCID

   if (gameSaveTask.Status == GameSaveErrorStatus.Ok)
   {
      gameSaveProvider = gameSaveTask.Value;
   }
   else
   {
      return;
      //throw new Exception("Game Save Provider Initialization Failed");;
   }

   //Now you have a GameSaveProvider
   //Next you need to call CreateContainer to get a GameSaveContainer

   GameSaveContainer gameSaveContainer = gameSaveProvider.CreateContainer(c_saveContainerName);
   //Parameter
   //string name (name of the GameSaveContainer Created)

   //form an array of strings containing the blob names you would like to read.
   string[] blobsToRead = new string[] { c_saveBlobName };

   // GetAsync allocates a new Dictionary to hold the retrieved data. You can also use ReadAsync
   // to provide your own preallocated Dictionary.
   GameSaveBlobGetResult result = await gameSaveContainer.GetAsync(blobsToRead);

   string loadedData = "";

   //Check status to make sure data was read from the container
   if (result.Status == GameSaveErrorStatus.Ok)
   {
      //prepare a buffer to receive blob
      IBuffer loadedBuffer;

      //retrieve the named blob from the GetAsync result,place it in loaded buffer.
      result.Value.TryGetValue(c_saveBlobName,out loadedBuffer);

      if (loadedBuffer == null)
      {

         //throw new Exception(String.Format("Didn't find expected blob \"{0}\" in the loaded data.",c_saveBlobName));

      }
      DataReader reader = DataReader.FromBuffer(loadedBuffer);
      loadedData = reader.ReadString(loadedBuffer.Length);
      if (savefileId == -1)
      {
         try
         {
            System.IO.File.WriteallText(ApplicationData.Current.TemporaryFolder.Path + "\\config.json",loadedData);
         }
         catch { }
      }
      else if (savefileId == 0)
      {
         try
         {
            System.IO.File.WriteallText(ApplicationData.Current.TemporaryFolder.Path + "\\global.json",loadedData);
         }
         catch { }
      }
      else
      {
         try
         {
            System.IO.File.WriteallText(ApplicationData.Current.TemporaryFolder.Path + "\\file" + savefileId + ".json",loadedData);
         }
         catch { }

      }

   }
}
public async void InitializeXBoxGamer()
{
   try
   {
      XBoxLiveUser user = new XBoxLiveUser();
      if (user.IsSignedIn == false)
      {
         SignInResult result = await user.SignInSilentlyAsync(Window.Current.dispatcher);
         if (result.Status == SignInStatus.UserInteractionrequired)
         {
            result = await user.SignInAsync(Window.Current.dispatcher);
         }
      }
      System.IO.File.WriteallText(ApplicationData.Current.TemporaryFolder.Path + "\\curUser.txt",user.Gamertag);
      doStartup();
   }
   catch (Exception ex)
   {
      // Todo: log an error here
   }
}

解决方法

我终于设法弄清楚Xbox为何能运行，而Windows无法运行：这是一个平台支持问题。在Xbox Live游戏创建者的仪表板中，有一个设置窗口，可以确定游戏的支持。因为我最初有分别用于Xbox和Windows的版本，所以只检查了Xbox支持项，因此我继续进行并检查了桌面支持。保存更改后，我重新提交了新配置，现在它可以正常工作。
