singlar/negotiate no json response - no singlar/connect

Question

I'm trying to use the SignalR library in the project that we are currently working on. I've read a few blogs, looked at a few stackoverflow answers and checked the documentation of signalr but without any luck. The code below is only the simplest sample that I'm trying to make working.

I'm using SignalR 1.0.1 with Hubs, jquery 2.0.0, ASP.NET MVC2, .NET Framework 4, signalr/hubs are loaded through Url.Content("~/signalr/hubs"). In the source code of the page, when I click signalr/hubs I can see SignalR generated js code.

I've also added RouteTable.Routes.MapHubs(); to the beginning of Application_Start() My Hub:

public class Chat : Hub
{
    public void Send()
    {
        Clients.All.addMessage();
    }
}

Client code in jQuery document ready block

$(function() {
    var chat = $.connection.chat;

    chat.client.addMessage = function() {
        console.log("hello here");
    };

    $.connection.hub.logging = true;
    $.connection.hub.error(function() {
        console.log("An error occured1");
    });
    $.connection.hub.start()
        .done(function() {
            alert("Now connected!");
        })
        .fail(function() {
            console.log("Could not connect");
        });
});

The problem is that: http://localhost/EC/signalr/negotiate returns status 200 OK, but the response body is empty, so there is no connection created.

I've tried to set runAllManagedModulesForAllRequests="true", but did not changed anything, also tried $.connection.hub.url = 'http://localhost/EC/signalr'; but again no effect.

I also kept my hubs class in Hubs folder or in root of the project.

I would appreciate any help with this, as I'm running out of ideas, how and where to look for solution.

Answer 1

@suleks ,

By any chance is your page missing the "signalr/hubs" script?

<script src="signalr/hubs" type="text/javascript"></script>

Ok, so it occured that there were problems with our servers, which were blocking everything. Thanks for looking into our problem. Question can be closed.
