angular-sails websocket url undefined ( ws://www.undefined)

Question

I am using sails 0.10.5 and in angular frontend with angular-sails .

It gives an error like below on server side Whenever an api call by $sails.get

In My FrontEnd side controller code :

 io.sails.url = 'http://localhost:1337';

        io.socket.get('http://localhost:1337/admin/v1/user/subscribe', function (body, response) {
            console.log('Sails responded with: ', body);
            console.log('with headers: ', response.headers);
            console.log('and with status code: ', response.statusCode);
        });

and console is

 Sails responded with:  Object {}
app.js:167 with headers:  Object {}
app.js:168 and with status code:  200

But in backend side sails console gives error like this

My route file is like this :

'get    /admin/v1/user/subscribe': 'UserController.subscribe',

And in UserController.js :

subscribe: function (req, res) {

        console.log('aaaaaaaaaaaaaaaaaaaa')

        User.find().exec(function(err,users){

            // subscribing this socket to User model classroom
            User.subscribe(req.socket);

            // subscribing this socket to User model instance room
            User.subscribe(req.socket,users);

            console.log('subscribe')
        })


    }

For setting up Socket connection with server:

Include sails.io.js in index.html.
Create a global variable for io.sails.url and you'll need to tell the Sails socket client what URL to connect to:

io.sails.url = 'http://localhost:1337';

Put this anywhere before you start making socket calls; the library is smart enough to wait until its connected before trying to make the calls.

To Check if Socket is connected,

io.socket.get('http://localhost:1337/data', function (body, response) {
    console.log('Sails responded with: ', body);
    console.log('with headers: ', sailsResponseObject.headers);
    console.log('and with status code: ', sailsResponseObject.statusCode);
});

You should be able to see in the console whether or not the socket connected by looking for the "io.socket connected successfully." message.

The above code was about setting up socket connection as you requested.
Regarding your problem, Can you please provide some Code
