Nuget Gallery link : https://www.nuget.org/packages/ScClient.Official/

Usage using source files

Library is built on top of Websocket4Net and Newtonsoft.Json. Install those packages via nuget and add source files into project

Description

Create instance of Socket class by passing url of socketcluster-server end-point

    //Create a socket instance
    string url = "ws://localhost:8000/socketcluster/";
    var socket = new Socket(url);

Important Note : Default url to socketcluster end-point is always ws://somedomainname.com/socketcluster/.

Registering basic listeners

Create a class implementing BasicListener interface and pass it's instance to socket setListener method


        internal class MyListener : IBasicListener
        {
            public void OnConnected(Socket socket)
            {
                Console.WriteLine("connected got called");
            }

            public void OnDisconnected(Socket socket)
            {
                Console.WriteLine("disconnected got called");
            }

            public void OnConnectError(Socket socket, ErrorEventArgs e)
            {
                Console.WriteLine("on connect error got called");
            }

            public void OnAuthentication(Socket socket, bool status)
            {
                Console.WriteLine(status ? "Socket is authenticated" : "Socket is not authenticated");
            }

            public void OnSetAuthToken(string token, Socket socket)
            {
                socket.setAuthToken(token);
                Console.WriteLine("on set auth token got called");
            }

        }

        internal class Program
        {
            public static void Main(string[] args)
            {
                var socket = new Socket("ws://localhost:8000/socketcluster/");
                socket.SetListerner(new MyListener());
            }
        }
Connecting to server
  • For connecting to server:
    //This will send websocket handshake request to socketcluster-server
    socket.Connect();
  • By default reconnection to server is not enabled , to enable it :
    //This will set automatic-reconnection to server with delay of 3 seconds and repeating it for 30 times
    socket.SetReconnectStrategy(new ReconnectStrategy().SetMaxAttempts(30));
    socket.Connect()
  • To disable reconnection :
   socket.SetReconnectStrategy(null);

Emitting and listening to events

Event emitter
  • eventname is name of event and message can be String, boolean, Long or JSON-object
    socket.Emit(eventname,message);

    //socket.Emit("chat","Hi");
  • To send event with acknowledgement

    socket.Emit("chat", "Hi", (eventName, error, data) =>
    {
       //If error and data is String
       Console.WriteLine("Got message for :"+eventName+" error is :"+error+" data is :"+data);
    });
Event Listener
  • For listening to events :

The object received can be String, Boolean, Long or JSONObject.


    socket.On("chat", (eventName, data) =>
    {
        Console.WriteLine("got message "+ data+ " from event "+eventName);
    });
  • To send acknowledgement back to server

    socket.On("chat", (eventName, data, ack) =>
    {
        Console.WriteLine("got message "+ data+ " from event "+eventName);
        ack(name, "No error", "Hi there buddy");
    });

Implementing Pub-Sub via channels

Creating channel
  • For creating and subscribing to channels:
    var channel=socket.CreateChannel(channelName);
   //var channel=socket.CreateChannel("yolo");


    /**
     * without acknowledgement
     */
     channel.Subscribe();

    /**
     * with acknowledgement
     */

    channel.Subscribe((channelName, error, data) =>
    {
       if (error == null)
       {
             Console.WriteLine("Subscribed to channel "+channelName+" successfully");
       }
    });
  • For getting list of created channels :
    List<Socket.Channel> channels = socket.GetChannels();
  • To get channel by name :
    var channel=socket.GetChannelByName("yell");
    //Returns null if channel of given name is not present
Publishing event on channel
  • For publishing event :
       // message can have any data type
    /**
     * without acknowledgement
     */
     channel.Publish(message);

    /**
     * with acknowledgement
     */
       channel.Publish(message, (channelName, error, data) =>
       {
            if (error == null) {
               Console.WriteLine("Published message to channel "+channelName+" successfully");
            }
       });
Listening to channel
  • For listening to channel event :

    //If instance of channel exists
    channel.OnMessage((channelName, data) =>
    {
         Console.WriteLine("Got message for channel "+channelName+" data is "+data);
    });

    //or
    socket.OnSubscribe(channelName, (channelName, data) =>
    {
        Console.WriteLine("Got message for channel "+channelName+" data is "+data);
    });
Un-subscribing to channel

    /**
     * without acknowledgement
     */

     channel.Unsubscribe();

    /**
     * with acknowledgement
     */

    channel.Unsubscribe((name, error, data) =>
    {
        if (error == null) {
            Console.WriteLine("channel unsubscribed successfully");
        }
    });
Handling SSL connection with server

To enable or disable SSL certficate verification use


socket.SetSSLCertVerification(true/false);
Setting HTTP proxy with server

//args, string : host , int : port
socket.SetProxy(host,port);
