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;
}
}
