Laravel/PHP-从子类返回/重定向 [英] Laravel/PHP - returning/redirecting from child class

问题描述

这是我的孩子控制者:

class VolunteersController extends \BaseController
{
    public function index()
    {
        $this->checkForRoles(['admin']);
        //list some secret stuff for admin
    }
}

在我的基本控制器中，我这样做:

In my base controller I did this:

class BaseController extends Controller
{
    protected function checkForRoles($roles)
    {
        foreach ($roles as $role) {
            if (!(Auth::user()->hasRole($role))) {
                return Redirect::to('/');
            }
        }
    }
}

现在，我所期望的是，如果BaseController中的角色不是管理员，则行return Redirect::to('/');会将用户重定向到首页.

Now what I expected was that the line return Redirect::to('/'); in BaseController would redirect the user to home page if his role is not admin.

但是不会发生. //list some secret stuff for admin在任何情况下都会执行.

But it does not happen. //list some secret stuff for admin gets executed in any case.

修改: 有人可能会奇怪，为什么我不使用过滤器.是的，所需的功能是过滤器，但显然过滤器尚不支持Laravel中的数组参数.如您所见，我需要将一组角色传递给该函数.

Some people may wonder, why am I not using filters. Well yeah, the desired functionality is of filters but apparently filters do not support array arguments in Laravel yet. And as you can see, I need to pass an array of roles to the function.

请帮助.

推荐答案

仅当VolunteersController :: index()返回"Redirect"时，重定向才会发生.在您的代码中没有.

The redirect will happen only if VolunteersController::index() will return a "Redirect". It does not do so in your code.

如果有的话

class VolunteersController extends \BaseController
{
    public function index()
    {
        if ($res = $this->checkForRoles(['admin'])) return $res;
        //list some secret stuff for admin
    }
}
