Laravel: Sentry won't check if user is logged in

在使用Sentry bundle时，我创建了LoginController控制器来检查用户是否登录了他们被重定向的地方，以防他们没有。我的目的是将所有受限页面扩展到该类，以使代码更高效。但为什么行不通呢?

登录控制器:

// Extends the BaseController
class LoginController extends BaseController {
    public function __construct() {
        if(!Sentry::check()) return Redirect::to('login');
    }
}

我的实际控制器:

class MainController extends LoginController {
    public function getIndex() {
        if(Sentry::getUser()->hasAccess('view dashboard')) {
            return View::make('admin.index');
        } else {
            return 'You have no access!';
        }
    }
}

我总是得到错误:

Call to a member function hasAccess() on a non-object

工作原理:如果我在getIndex()中直接添加if(!Sentry::check()) return Redirect::to('login');而不是__construct，重定向工作正常。为什么?

注意错别字!__construct缺少s.

我认为__construct()方法只会在初始化时被调用。在您的例子中，您是扩展它而不是初始化它。如果你这样做，它可能会工作。

class MainController extends LoginController {
public function __construct()
{
   return parent::__construct();
}
public function getIndex() {
        if(Sentry::getUser()->hasAccess('view dashboard')) {
            return View::make('admin.index');
        } else {
            return 'You have no access!';
        }
    }

我也认为问题是

public function __construct()
{
   parent::__construct();
}

如果你想执行父类，你需要调用父类的构造

可能是因为你没有登录?

你可能需要这样的东西

try
{
    // Get the current active/logged in user
    $user = Sentry::getUser();
}
catch (Cartalyst'Sentry'Users'UserNotFoundException $e)
{
    // User wasn't found, should only happen if the user was deleted
    // when they were already logged in or had a "remember me" cookie set
    // and they were deleted.
}
