For Rails 5 API mode:

application_controller.rb

class ApplicationController < ActionController::API
   include ActionController::Cookies
   ...
   token = request.headers["Authorization"].to_s
   user = User.find_by(authentication_token: token)
   cookies.signed[:user_id] = user.try(:id)

connection.rb

class Connection < ActionCable::Connection::Base
   include ActionController::Cookies
   ...
   if cookies.signed[:user_id] && current_user = User.where(id: cookies.signed[:user_id]).last
     current_user
   else
     reject_unauthorized_connection
   end

config/application.rb

config.middleware.use ActionDispatch::Cookies
