从 url 中隐藏代码点火器控制器和方法名称

我的网址是这样的：http://example.com/controller/method/param1/param2/param3/param4

我的目标是：http://example.com/param1/param2/param3/param4

在这里，我的控制器"主页"和"阅读"。我还在底部包含我的视图和路由配置。

<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Home extends CI_Controller {
    public function __construct()
    {
        parent::__construct();
    }
    /*
    *   Index method
    */
    public function index() {
        $this->db->select('a.*, c.*');
        $this->db->join('category as c', 'c.catid=a.catid');
        $this->db->limit(10);
        $this->db->order_by('a.id', 'DESC');
        $data['query'] = $this->db->get('article as a');
        $this->load->view('header');
        $this->load->view('home_view', $data);
        $this->load->view('footer');
    }
}

<?php defined('BASEPATH') OR exit('No direct script access allowed');
    class Read extends CI_Controller {
        public function __construct()
        {
            parent::__construct();
        }
        /*
        *   Index method
        */
        public function index() {
            $id = isset($this->uri->segment(3)) ? $this->uri->segment(3) : FALSE;
            $this->db->select('a.*, c.*');
            $this->db->join('category as c', 'c.catid=a.catid');
            $this->db->where('p.id', $id);
            $this->db->limit(1);
            $data['query'] = $this->db->get('article as a');
            $this->load->view('header');
            $this->load->view('single_view', $data);
            $this->load->view('footer');
        }
    }

home_view.php

请看下面的锚点，这是我制作http://example.com/param1/param2/param3/param4的目标

<div class="post-content">
    <ul>
        <?php foreach( $query->result() as $post ) : ?>
        <li><a href="<?php echo site_url($post->term_name.'/'.$post->term_id.'/'.$post->id.'/'.strtolower(url_title($post->title))); ?>"><?php echo $post->title ?></a></li>
        <?php endforeach; ?>
    </ul>
</div>

当我定义控制器名称时，这没有问题。但是我无法弄清楚我的单个帖子的网址如何仅包含这四个参数

<?php echo site_url('read/'.$post->term_name.'/'.$post->term_id.'/'.$post->id.'/'.strtolower(url_title($post->title))); ?>

在我的路由配置下方：

$route['(:any)'] = "read/index/$1";

任何帮助和建议将不胜感激。

此致敬意
