thinkphp控制器权限 （在构造函数时统一加权限等）

class CircleTopicController extends Controller{    //检查是否登录    public function _initialize() {        check_login();    }    

/* * 检查是否登录 */function check_login(){    if(!isset($_SESSION['loginstate']) || $_SESSION['loginstate']==0){        $_SESSION['loginstate'] = 0;        unset($_SESSION['adminname']);        $login_url = C('APP');        header('Location: '.$login_url.'/Index/Index/login');    }else{//否则检查权限        check_rbac();    }}

/* * 检查权限 */function check_rbac(){    $role_name = $_SESSION['adminname'];    $rbac_id  =explode(',',M('admins')->where("adminname = "."'$role_name'")->getField('rbac_id'));    $rbac_controll_info = [];    foreach($rbac_id as $key=>$value){        $rbac_controll_info[] = M('admins_rbac')->where("id = ".$value)->getField('controller');    }    $rbac_controll_info = explode(',',implode(',',$rbac_controll_info));    if($rbac_controll_info){        $current_controll = explode('/',$_SERVER['PHP_SELF'])[2];        if(!in_array($current_controll,$rbac_controll_info)){            echo "<script>alert('You do not have permission to access!');history.go(-1);</script>";            exit();        }    }else{        echo "<script>alert('You do not have permission to access!');history.go(-1);</script>";        exit();    }}
