php后台如何避免用户直接进入方法实例 |
本文标签:php,后台,用户 1)创建BaseController控制器继承Controller(后台的一切操作要继承BaseController): 在BaseController里面添加: 复制代码 代码如下: public function checkLogin() { if (Yii::app()->authority->isLogin() == Yii::app()->authority->getStatus(NOTLOGIN)) { $url = $this->createUrl(user/login); if (Yii::app()->request->isPostRequest && Yii::app()->request->isAjaxRequest) { echo json_encode(array(code => -101, message => 用户未登录 。, callback => window.location=" . $url . ";)); } else if (Yii::app()->request->isAjaxRequest) { echo <script language="javascript">window.location=" . $url . ";</script>; } else { $this->redirect($url); } exit; } return true; } 在components目录下创建Authority.php文件: 复制代码 代码如下: <?php /** * 权限检查组件 */ class Authority extends CComponent { private $NOTLOGIN = -1; private $FAILED = -2; private $PASS = 1; public function init() { } /** * 检查是否登陆 * @return boolean */ function isLogin() { return isset(Yii::app()->session[user]) ? $this->PASS : $this->NOTLOGIN; } /** * 获取状态值 * @param string $name * @return int */ public function getStatus($name){ return $this->$name; } } |
