这是我的控制器

class Transport extends CI_Controller {

    /**
     * Index Page for this controller.
     *
     * Maps to the following URL
     *      http://example.com/index.php/welcome
     *  - or -
     *      http://example.com/index.php/welcome/index
     *  - or -
     * Since this controller is set as the default controller in
     * config/routes.php, it's displayed at http://example.com/      
     *
     * So any other public methods not prefixed with an underscore will
     * map to /index.php/welcome/<method_name>
