Question

我正在尝试从服务器向特定客户端发送有关事务更改的通知。到目前为止，我在本地和开发环境中做得很好，但是在LIVE中我们有3个带有负载均衡器的应用程序池（3个物理服务器）（所有三个都有相同的机器密钥）。

所以看起来当客户端连接在同一个池上的服务器端触发通知时 - 它可以工作，但如果池不同则不起作用。

任何人都可以建议如何处理这个 - 或者问题可能是错误的代码（不正确的集线器上下文处理或其他东西）。我是SignalR的新手 - 所以使用SignalR文档中的消息广播示例。

这是mu hub：

SELECT
  { [Measures].[Reseller Sales Amount] }
  DIMENSION PROPERTIES PARENT_UNIQUE_NAME , HIERARCHY_UNIQUE_NAME , CUSTOM_ROLLUP , UNARY_OPERATOR , KEY0 ON 0
, ORDER
  ( HIERARCHIZE
    ( HIERARCHIZE ( [Geography].[Geography].Levels ( 0 ).Members )
    )
  , ([Measures].[Reseller Sales Amount])
  , BDESC
  )
  DIMENSION PROPERTIES PARENT_UNIQUE_NAME , HIERARCHY_UNIQUE_NAME , CUSTOM_ROLLUP , UNARY_OPERATOR , KEY0 ON 1
FROM
( SELECT
    { Generate
      ( [Geography].[Geography].Levels ( 3 ).Members
      , TopCount
        ( Filter
          ( [Geography].[Geography].CurrentMember.Children
          , NOT IsEmpty ( [Measures].[Reseller Sales Amount] )
          )
        , 3
        , [Measures].[Reseller Sales Amount]
        )
      )
    } ON COLUMNS
  FROM
  ( SELECT
      { Generate
        ( [Geography].[Geography].Levels ( 2 ).Members
        , TopCount
          ( Filter
            ( [Geography].[Geography].CurrentMember.Children
            , NOT IsEmpty ( [Measures].[Reseller Sales Amount] )
            )
          , 3
          , [Measures].[Reseller Sales Amount]
          )
        )
      } ON COLUMNS
    FROM
    ( SELECT
        { Generate
          ( [Geography].[Geography].Levels ( 1 ).Members
          , TopCount
            ( Filter
              ( [Geography].[Geography].CurrentMember.Children
              , NOT IsEmpty ( [Measures].[Reseller Sales Amount] )
              )
            , 3
            , [Measures].[Reseller Sales Amount]
            )
          )
        } ON COLUMNS
      FROM
      ( SELECT
          { Generate
            ( [Geography].[Geography].Levels ( 0 ).Members
            , TopCount
              ( Filter
                ( [Geography].[Geography].CurrentMember.Children
                , NOT IsEmpty ( [Measures].[Reseller Sales Amount] )
                )
              , 3
              , [Measures].[Reseller Sales Amount]
              )
            )
          } ON COLUMNS
        FROM
        ( SELECT
            { [Geography].[Geography].Levels ( 0 ).Members } ON COLUMNS
          FROM [Adventure Works]
        )
      )
    )
  )
)
CELL PROPERTIES BACK_COLOR , CELL_ORDINAL , FORE_COLOR , FONT_NAME , FONT_SIZE , FONT_FLAGS , FORMAT_STRING , VALUE , FORMATTED_VALUE , UPDATEABLE , ACTION_TYPE

这是提供静态实例的类：

public class ExampleClassHub : Hub
{
    private readonly ExampleClass _ExampleClassInstance;
    public ExampleClassHub() : this(ExampleClass.Instance) { }

    public ExampleClassHub(ExampleClass ExampleClassInstance)
    {
        _ExampleClassInstance = ExampleClassInstance;
    }
}

因此，从服务器端通知按以下方式触发：

public class ExampleClass
{
    private readonly static Lazy<ExampleClass> _instance = new Lazy<ExampleClass>(() =>
        new ExampleClass(GlobalHost.ConnectionManager.GetHubContext<ExampleClassHub>().Clients));

    private IHubConnectionContext<dynamic> Clients { get; set; }

    private ExampleClass(IHubConnectionContext<dynamic> clients)
    {
        Clients = clients;
    }

    public static ExampleClass Instance
    {
        get
        {
            return _instance.Value;
        }
    }

    public void NotifyTransactionChange(int userId, string tid, bool isTransactionSuccessfull)
    {
        string json = JsonConvert.SerializeObject(new Notification { UserId = userId, Tid = tid, IsTransactionSuccessful = isTransactionSuccessfull });
        Clients.User(userId.ToString()).notifyTransactionStateChange(json);
    }


    class Notification
    {
        public int UserId { get; set; }
        public string Tid { get; set; }
        public bool IsTransactionSuccessful { get; set; }
    }
}
