问题:

Hi I am using Signal R in my asp dot net web application. Here I am calling client from outside to hub class using IHubContext. I need to get current userconnection id in order to send message to current called user only.How can I get it?

回答1:

Yep. You can use $.connection.hub.id

回答2:

There's another way also, you can get connection id into your controller from hub by invoking a method of hub and you can return the required ID from there.

Controller Code

var HubContext = GlobalHost.ConnectionManager.GetHubContext<"ChatHub">(); //`ChatHub` can be your Hub Name ChatHub HubObj= new ChatHub(); var RequiredId= HubObj.InvokeHubMethod();

Code inside Hub

public string InvokeHubMethod() {      return "ConnectionID"  //ConnectionID will the Id as string that you want outside the hub }

This works for me:

var hub = $.connection.someHub; // After connection is started console.log(hub.connection.id);

回答4:

For a .NET Client it is on the Connection object, inherited by HubConnection.

Connection.ConnectionId

So typically can be found on

hubConnection.ConnectionId

回答5:

use the following code it works for me.

in the hub class.

 public static ConcurrentDictionary<string, MyUserType> MyUsers = new ConcurrentDictionary<string, MyUserType>();        public override Task OnConnected()     {         MyUsers.TryAdd(Context.User.Identity.Name, new MyUserType() { ConnectionId = Context.ConnectionId,UserName=Context.User.Identity.Name });         string name = Context.User.Identity.Name;         Groups.Add(Context.ConnectionId, name);          return base.OnConnected();     }

in the hub class file create the following class

public class MyUserType {     public string ConnectionId { get; set; }     public string UserName { get; set; }  }

and outside the hub class.

  var con = MyHub1.MyUsers;        var conId =con.Select(s => s.Value).Where(s => s.UserName == User.Identity.Name).FirstOrDefault();
