How to write data to session when working with socket.io Node.js?

Question

JavaScript

I started rewriting Ajax requests for sockets, and ran into a problem, let's say I'm doing authorization through a socket, and in case of successful authorization, I need to write the user id to the session, with ajax there was a request in which there was access to the request.session session, but when processing requests for there is no request on sockets, and how do I access the session?

io.on('connection', function(client){
    client.on('login', function (data) {
        console.log(data);
        if (data.Login && data.Password)
        {
            mysql.select("SELECT id FROM users where md5(Login) = md5(?) and Password = md5(?)", [data.Login, data.Password], function (user) {
                if (user.err) client.emit('finishlogin', {result:'err', message:'Произошла ошибка попробуйте позже'});
                else {
                    if (user.result.length == 0)  client.emit('finishlogin', {result:'err', message:'Не правильный логин или пароль'});
                    else {
                        client.emit('finishlogin', {result:'ok', message:''});
/*

*/
                    }
                }
            });
        }

    });
});
