在core里新建MY_controller

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class MY_Controller extends CI_Controller{
public function __construct(){
parent::__construct();

echo "你当前的控制器："."<font style='color:red'>".$this->router->class."</font>";
echo "<br>";
echo "你当前的方法："."<font style='color:red'>".$this->router->method."</font>";
}

}

?>

C层

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Index extends MY_Controller {

/*
