php后台如何避免用户直接进入方法实例

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 '';
            } 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:


class Authority extends CComponent {
    private $NOTLOGIN = -1;
    private $FAILED = -2;
    private $PASS = 1;

    public function init() {

    }

   
    function isLogin() {
        return isset(Yii::app()->session['user']) ? $this->PASS : $this->NOTLOGIN;
    }

  
   
    public function getStatus($name){
        return $this->$name;
    }
}
