Connect client socket to a cookie

I am making a chat program.

I am using an Nginx server and NodeJS.

I have setup a websocket via ssl and that works fine.

I have decided to use cookies for authentication.

There are two functions which are crucial:

mconnection.prototype.make_server_https=function(){
console.log('Make server https');

var cthis=this;
var server_https=modules.https.createServer({
    key: this.ssl_key,
    cert:this.ssl_cert,
    ca:this.ssl_ca
    },(request,response)=>{
        console.log('### CreateServer ###');

        console.log('CreateServer, Request:');
        console.log(request);

        console.log('CreateServer, Response:');
        console.log(response);

        console.log('######');

and

mconnection.prototype.make_server_websocket=function(){
var server_websocket=new modules.ws.Server({server:this.server_https});

var cookie = require("cookie");

var cthis=this;
//whenever a new client connects with the server.
server_websocket.on('connection', function(client_socket, request){
    console.log('### On Connection ###');

    console.log('OnConnection, Client Socket:');
    console.log(client_socket);
    console.log('OnConnection, Request:');
    console.log(request);

    console.log('######');

If I do state the port number in the client url,
function make_server_https gets run and inside there i can access the cookie and set it via the response object.

but in the original url,
function make_server_websocket gets run, and there i have access to the client_socket on the server. But there it seems i dont have access to the cookies.

I need to client_websocket to start the connection with this given client. And I need to tie it somehow with the cookies login information.

But i never have both at the same time so i dont get how i could connect them to make the login happen.

I am probably misunderstanding something, any help in the right direction would really be appreciated.
