代码点火器中的uri_segment()会导致未定义方法的致命错误

Question

我的路线结构是：

$route['404_override']          = 'home/check_path';

我的home.php check_path()方法是：

public function check_path() {
        $slug = $this->uri_segment(1); //<- This is line 68
        //check if event exists
        $event_check = $this->event_model->get_event_id_from_slug($slug);
        if($event_check) {
            redirect('events/view/'.$slug);
        }else{
            redirect('home/not_found');
        }
    }

但是，当我编写http://mypage.com/anything-here时，会显示错误：

Fatal error: Call to undefined method Home::uri_segment() in /var/www/html/99fest/application/controllers/home.php on line 68

改变这一点：

$slug = $this->uri_segment(1); 

通过以下方式：

$slug = $this->uri->segment(1)
