Signalr & WebSocketSharp in Unity3d

Question

Currently, I have created a simple Signalr hub that I click on posts from a Unity5 project. Given that the SignalR2 client does not work with Unity5, I use websocketsharp to intercept websocket frames. Messages are successfully transferred to the hub, but when I try to call the method on the client, I do not get the payload string, only the message identifier {"I": 0}

Looking through the SignalR documentation, it looks like this is being sent last, but I have no idea how I can hold it. I am sure that this is something simple, but for life I can not understand.

UPDATE

Upon request, I added the code for the project below ...

SignalRClient.cs

 using System; using System.Collections.Generic; using System.IO; using System.Net; using Newtonsoft.Json; using WebSocketSharp; namespace Assets.Scripts { class SignalRClient { private WebSocket _ws; private string _connectionToken; private Dictionary<string, UnTypedActionContainer> _actionMap; private readonly string _socketUrl = "http://localhost/"; private readonly string _socket = "ws://localhost/"; public SignalRClient() { _actionMap = new Dictionary<string, UnTypedActionContainer>(); var webRequest = (HttpWebRequest)WebRequest.Create(_socketUrl + "/signalr/negotiate?connectionData=%5B%7B%22name%22%3A%22myHub%22%7D%5D&clientProtocol=1.3"); var response = (HttpWebResponse)webRequest.GetResponse(); using (var sr = new StreamReader(response.GetResponseStream())) { var payload = sr.ReadToEnd(); UnityEngine.Debug.Log(payload); _connectionToken = Uri.EscapeDataString(JsonConvert.DeserializeObject<NegotiateResponse>(payload).ConnectionToken); //UnityEngine.Debug.Log(_connectionToken); } } public void Open() { _ws = _ws == null ? new WebSocket(_socket + "signalr/connect?transport=webSockets&connectionToken=" + _connectionToken) : new WebSocket(_socket + "signalr/reconnect?transport=webSockets&connectionToken=" + _connectionToken); AttachAndConnect(); } public void Close() { _ws.Close(); } public void SendMessage(string name, string message) { //{"H":"chathub","M":"Send","A":["tester","hello"],"I":0} var payload = new RollerBallWrapper() { H = "myhub", M = "Send", A = new[] { name, message }, I = 12 }; var wsPacket = JsonConvert.SerializeObject(payload); _ws.Send(wsPacket); } private void AttachAndConnect() { _ws.OnClose += _ws_OnClose; _ws.OnError += _ws_OnError; _ws.OnMessage += _ws_OnMessage; _ws.OnOpen += _ws_OnOpen; _ws.Connect(); } void _ws_OnOpen(object sender, EventArgs e) { UnityEngine.Debug.Log("Opened Connection"); } // // This seems to be retriving the last frame containing the Identifier void _ws_OnMessage(object sender, MessageEventArgs e) { //UnityEngine.Debug.Log(e.Data); // Returns {"I":"0"} ???? } void _ws_OnError(object sender, WebSocketSharp.ErrorEventArgs e) { UnityEngine.Debug.Log(e.Message); } void _ws_OnClose(object sender, CloseEventArgs e) { UnityEngine.Debug.Log(e.Reason + " Code: " + e.Code + " WasClean: " + e.WasClean); } public void On<T>(string method, Action<T> callback) where T : class { _actionMap.Add(method, new UnTypedActionContainer { Action = new Action<object>(x => { callback(x as T); }), ActionType = typeof(T) }); } } internal class UnTypedActionContainer { public Action<object> Action { get; set; } public Type ActionType { get; set; } } class MessageWrapper { public string C { get; set; } public RollerBallWrapper[] M { get; set; } } class RollerBallWrapper { public string H { get; set; } public string M { get; set; } public string[] A { get; set; } public int I { get; set; } } } 

Myhub.cs

 using System; using System.Threading; using System.Threading.Tasks; using Microsoft.AspNet.SignalR; public class MyHub : Hub { public void Send(string name, string message) { var myConn = Context.ConnectionId; Clients.All.broadcastMessage("John", "Hello"); } }

The problem is connecting to the network. I had the following:

 new WebSocket(_socket + "signalr/connect?transport=webSockets&connectionToken=" + _connectionToken) 

As a result, there were no 2 critical request parameters: connectionData and tid in addition to connectionToken and transport . I mistakenly believed that they were not needed.

I hope this helps anyone who hasn't read documentation like me :)
