我如何获得所有团队服务帐户中的所有工作项目？

Question

我正在使用.NET库访问Visual Studio Team Services，并试图解决微软方面的一个明显的设计缺陷。显然，每个服务器/帐户不能有多个集合，所以我必须使用多个帐户，在这个例子中我将其称为集合，因为微软甚至已经明确表示they map to the same thing。

我实际上想要实现的目标是列出所有我所属集合中的所有工作项目。我有一个使用GetAllCollections（）获取我的所有集合的QueryWorkItems（）方法。这种方法已经过测试，它的工作原理，它返回我有两个帐户。触发整个事物的顶层方法是AssignedWorkItems（）。我的代码如下：

 public static List<TfsTeamProjectCollection> GetAllCollections() 
     { 
      // Get collections/accounts associated with user 
      string request = "https://app.vssps.visualstudio.com/_apis/Accounts?memberId=" + versionControl.AuthorizedIdentity.TeamFoundationId + "&api-version=3.2-preview"; 
      string content = MakeRequestToAPI(request).Result; 
      dynamic results = JsonConvert.DeserializeObject<dynamic>(content); 
      List<TfsTeamProjectCollection> collections = new List<TfsTeamProjectCollection>(); 
      // Iterate through all collections 
      Parallel.ForEach((IEnumerable<dynamic>)results.value, collection => 
      { 
       TfsTeamProjectCollection col = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri((string)collection.accountUri)); 
       collections.Add(col); 
      }); 
      return collections; 
     } 


     public static List<WorkItem> QueryWorkItems(string query) 
     { 
      List<WorkItem> workItems = new List<WorkItem>(); 
      List<TfsTeamProjectCollection> collections = GetAllCollections(); 
      //Parallel.ForEach(collections, collection => 
      foreach(var collection in collections) 
      { 
       WorkItemCollection items = collection.GetService<WorkItemStore>().Query(query); 
       // Add each work item to the overall list 
       Parallel.For(0, items.Count, i => 
       { 
        Console.WriteLine(items[i].Title); 
        lock (workItems) 
        { 
         workItems.Add(items[i]); 
        } 
       }); 
      } 

      return workItems; 
     } 

     public static List<WorkItem> AssignedWorkItems() 
     { 
      Init(); //initializes variables like projectName, workItemStore and VersionControlServer(versionControl) 
      string myItems = "select * from issue where [System.AssignedTo]=@me"; 
      return QueryWorkItems(myItems); 
     } 

当我打电话的AssignedWorkItems方法我得到一个登录提示，即使我有一个默认的连接已经建立：

我输入我的凭据后，虽然，在这条线：

WorkItemCollection items = collection.GetService().Query(query);

我得到以下错误：

An unhandled exception of type 'Microsoft.TeamFoundation.TeamFoundationServiceUnavailableException' occurred in Microsoft.TeamFoundation.Client.dll

Additional information: TF31002: Unable to connect to this Team Foundation Server: https://xxxxxx.vssps.visualstudio.com/ .

Team Foundation Server Url: https://xxxxxx.vssps.visualstudio.com/

Possible reasons for failure include:

• The name, port number, or protocol for the Team Foundation Server is incorrect.

• The Team Foundation Server is offline.

• The password has expired or is incorrect.

有趣的是我每次运行这个错误中提到的URL在我有两个集合之间来回切换。任何想法为什么会发生这种情况？

我可以测试方法QueryWorkItems成功。

根据你得到的错误信息，看起来好像存储在collections中的VSTS URL格式为https://account.vssps.visualstudio.com而不是https://account.visualstudio.com。因此，请确认方法GetAllCollections中存储的网址是否正确。

我用这个GetAllCollections方法来验证QueryWorkItems：

public static List<TfsTeamProjectCollection> GetAllCollections() 
{ 

    List<TfsTeamProjectCollection> collections = new List<TfsTeamProjectCollection>(); 

    NetworkCredential cred1 = new NetworkCredential("username for Alternate authentication", "password for Alternate authentication"); 
    TfsTeamProjectCollection tpc1 = new TfsTeamProjectCollection(new Uri("https://account1.visualstudio.com"), cred1); 

    collections.Add(tpc1); 

    NetworkCredential cred2 = new NetworkCredential("username for Alternate authentication", "password for Alternate authentication"); 
    TfsTeamProjectCollection tpc2 = new TfsTeamProjectCollection(new Uri("https://account2.visualstudio.com"), cred2); 

    collections.Add(tpc2); 
    return collections; 
}
