thinkPHP框架实现类似java过滤器的简单方法示例

<?php
/**
 * Created by PhpStorm.
 * User: xieyicheng
 * Date: 2014/12/11
 * Time: 14:43
 */
namespace Admin\Controller;
use Think\Controller;
class CommonController extends Controller
{
  public function _initialize()
  {
    if(!isset($_SESSION['username'])) {
      redirect( U('Admin/Login/index'), 0);//没登陆，跳转到登陆页
    }
  }
}

<?php
/**
 * Created by PhpStorm.
 * User: xieyicheng
 * Date: 2014/12/4
 * Time: 13:06
 */
namespace Admin\Controller;
use Home\Model;
use Admin\Model\Shop;
class FileController extends CommonController
{
  public function index()
  {
    $this->display();
  }
}
