群聊信号R与Web API

Question

下面我有三个表，这是用于GroupChat，首先我创建该组的所有数据将被插入GroupTable，然后成功的groupCreation我打电话insertConnectionId函数将在后端调用MapGroupConnectionId，该后端生成SignalR连接ID并使用groupId和groupCreaterId插入GroupTable，其工作正常，并且我拥有包含Friends ID的Group Friends Table，现在当任何朋友向特定Group发送消息时，我需要通过SignalR将消息发送给所有在特定组中的人，我想，我将把组表中的groupConnectionID分配给与该组相关的所有成员，然后我可以发送消息给该特定组，由Gr接收oupFriends，我中心只为Hub.Client.ALL而不适用于其他功能，请指导我，如果我在错误的方式做这件事，我是新来signalR

//Group Table 

groupID groupName groupImage groupCreaterId groupConnectionId groupsignalrIsConnected 
    1   dude  someurl  421  somestringID  TRUE 
    2   god  someurl  444  somestringID  TRUE 
    3   heaven  someurl  543  Null    FALSE 
    4   hell  someurl  678  Null    FALSE 


//Group Friends Table 

groupFriendsTabID groupId groupFriendsId 
     111    2 444 
     112    3 678 
     113    2 421 
     114    4 444 
     115    1 543 
     116    4 421 
     117    1 678 
     118    2 543 
     119    3 444 


    //Group Message Table 

    groupMesTabId groupId groupsenderId groupMessage 
     22    1 543    hello 
     23    3 678    hi 


//My HUB 
[HubName("groupChatHub")] 
public class GroupChatHub : Hub 
{ 
    GroupRepository group= new GroupRepository(); 


    public void **MapGroupConnectionId**(long groupID,int groupCreatorId) 
     { 
     if (groupID != 0 && groupCreatorId!=0) 
      { 
      CBG.MapGroupConnectionId(groupID, Context.ConnectionId); 
       Clients.Client(Context.ConnectionId).configureUserSettings();} 
      } 

    public override Task OnConnected() 
    { 
     var connectionId = Context.ConnectionId; 
     return base.OnConnected(); 
    } 
    public override Task OnDisconnected(bool stopCalled) 
    { 
     var connectionId = Context.ConnectionId; 
     return base.OnDisconnected(stopCalled); 
    } 
    public override Task OnReconnected() 
    { 
     return base.OnReconnected(); 
    } 
} 

    //My WEBAPI// 
    public class GroupController : ApiControllerWithHub<GroupchatHub> 
    { 
     public IhttpActionResult InsertNewMessage(messageModel model) 
     { 
       //Here i am inserting new message to Database using some function it works fine// 

      after success of inserting message i need to send that message to groupmembers using signalr 

    //here i am fetching the connectionID through groupID from group table 
     var connectionID=repository.getConnection(model.groupID) 

      var messager = "11"; 
    Hub.Clients.All.getGroupChat(messager); // this works 

    Hub.Clients.clients(connectionID).getGroupChat(messager);this not working it except IList<string> 

    Hub.Clients.Groups(groupName,ConnectionID).getGroupChat(messager); this is not working 
     } 
    return ok(Model); 
    } 



//MyClientEnd// 

    var Grouphub 

//this insertConnectionId is called once the group is created on the success of group creation and SignalRconnectionstring is inserted in GroupTable 

function insertConnectionId(groupId,groupCreatorID) 
$.connection.hub.start().done(function() { 
    console.log('Now connected, connection ID=' + $.connection.hub.id); 
    console.log("Connected, transport = " +  $.connection.hub.transport.name); 
    Grouphub.server.mapGroupConnectionId(groupID, groupCreatorID); 
}); 
$.connection.hub.error(function (error) { 
    console.log('SignalR error: ' + error) 
}); 

}); 

Grouphub = $.connection.groupChatHub 
Grouphub.client.getGroupChat = function (data) { 
    alert("in"); 

}

我做了一个类似的项目像并且在不同的领域中使用它，

退房这个例子中它会帮助你:)
