身份验证组件的用户功能在多个路由的情况下不起作用

请使用它来获取用户会话数据。

public function login() {
 if ($this->request->is('post')) {
     if ($this->Auth->login()) {
    $this->redirect($this->Auth->redirect());
     } else {
    $this->Session->setFlash(__('Invalid username or password, try again'));
     }
 }
}
public function index() {
    pr($this->Auth->User());
}

        auth_helper:<?php
        defined('BASEPATH') OR exit('No direct script access allowed');
        if ( ! function_exists('auth'))
        {
            function auth()
            {
                $CI =& get_instance();
                $CI->load->model('Auth_model');
                return $CI->Auth_model;
            }
            function Adminauth($admin_id) 
            {
                if($admin_id == false)
                {
                    redirect('login');
                }
            }
        }
    auth_model:
