Fleck WebSockets

Question

I want to use Fleck for my WebSocket project, Server side looks pretty straightforward, but how to I differentiate opened connections. is there some sort of ID? The only way I can think of is to create GUID in OnOpen event and pass it back to client. is there a smarter solution?

Basic server set up:

socket.OnOpen = () =>
{
    Console.WriteLine("Open!"); 
    allSockets.Add(socket);
};

socket.OnClose = () =>
{
    Console.WriteLine("Close!");
    allSockets.Remove(socket);
};

socket.OnMessage = message =>
{
    Console.WriteLine(message);
    allSockets.ToList().ForEach(s => s.Send("Echo: " + message));
};

E.G. how would I make a chat room so all connection receive message except for the one sending.

Answer 1

Fleck now creates a Guid Id on the WebSocketConnectionInfo for every connected client. This will help in cases where multiple connections are using the same IP. See the related commit here:

Answer 2

Ask the user for a user name, and attach the username to the the socket address:

var wsimpl = window.WebSocket || window.mozWebSocket;
window.ws = new wsimpl('http://localhost:8080/myApp_' + userName, myProtocol);

then strip out the userName on the service side after the socket has been opened with socket.WebSocketConnectionInfo.path. There is also a clientip property that can be used also. I am doing this and it works great.
