Authenticate on SignalR console application from JS client RRS feed

  • Question

  • User1757586927 posted

    Hey there.
    Following scenario/my solution consists of the following: 

    Project one: (SELF HOST) I have a SignalR console application which handles the logic including the authentication process ( queries database with EF ).
    Project two: (CLIENT) I have an ASP.Net web application with an AngularJS client. 

    So far I can talk to the hub just fine. The problem is, I cannot seem to get the authentication to work. I've tried a bunch of things I've found but none of them worked. Most of them didn't even apply to my problem.. 

    Currently I've stripped my project back to the basics and I have the following code:

    Startup class:

        public class Startup
            public void Configuration(IAppBuilder app)

    My hub:

        public class systemHub : Hub
            public void Authenticate(String pLogin, String pPassword)
                User lUser = new UserManager().Authenticate(pLogin, pPassword);
    //this is where I'd want to send the auth cookie or whatever and contact the "loginCallback" function in my client
            public void Hello(String pMessage)

    Js client:

    hinagApp.controller('hinagController', function ($scope) {
        $(document).ready(function () {
            var conURL = 'http://localhost:8080/signalr';
            $.getScript(conURL + '/hubs', function () {
                $.connection.hub.url = conURL;
                var lHub = $.connection.systemHub;
    lHub.client.callbackFunc = function(pM){
    lHub.client.loginCallback = function (pSuccess) { if (pSuccess) { //if logged in lHub.server.hello("test"); } else { alert("fail"); } } $('#loginbutton').click(function () { lHub.server.authenticate($('#input_login').val(), $('#input_pass').val()); }); $.connection.hub.start(); }); }) });

    Hi SinnedB,

    Firstly, you could call a web service to check user's authentication status via jQuery AJAX, and you could start/stop connection in AJAX success callback function.

    $('#loginbutton').click(function () {
            type: "Post",
            url: "yoururl",
            data: "{'username and password'}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (data) {
                if (Authenticated) {
                    //start connection
            error: function (err) {

    Secondly, if you’d like to restrict which users or roles can access hub methods, please refer to this link.

    Which webservice? There is none or maybe I just don't understand.. 

    I only have a console application ( SignalR ) and the asp.net which acts as the client. Do I need to make another ASP.Net site to handle the authentication and how will SignalR know about it?
