Send auth_token for authentication to ActionCable

Question

module ApplicationCable
  class Connection < ActionCable::Connection::Base
    identified_by :current_user

    def connect
      #puts params[:auth_token]
      self         


        

Answer 1

It is also possible to pass the authentication token in the request headers and then validate the connection by accessing the request.headers hash. For example, if the authentication token were specified in a header called 'X-Auth-Token' and your User model have a field auth_token you could do:

module ApplicationCable
  class Connection < ActionCable::Connection::Base
    identified_by :current_user

    def connect
      self.current_user = find_verified_user
      logger.add_tags 'ActionCable', current_user.id
    end

    protected

    def find_verified_user
      if current_user = User.find_by(auth_token: request.headers['X-Auth-Token'])
        current_user
      else
        reject_unauthorized_connection
      end
    end
  end
end
