该网页在幼虫4中有一个重定向循环

Question

我忙于教程，最后收到的错误是

  

此网页有重定向循环

我知道问题出现在我的routes.php

中

Route::group(["before" => "guest"], function(){
    $resources = Resource::where("secure", false)->get();

    foreach($resources as $resource){
        Route::any($resource->pattern, [
            "as" => $resource->name,
            "uses" => $resource->target
        ]);
    }
});

Route::group(["before" => "auth"], function(){
    $resources = Resource::where("secure", true)->get();

    foreach($resources as $resource){
        Route::any($resource->pattern, [
            "as" => $resource->name,
            "uses" => $resource->target
        ]);
    }
});

UserController中

class UserController extends \BaseController {

    public function login()
    {
        if($this->isPostRequest())
        {
            $validator = $this->getLoginValidator();

            {
                $credentials = $this->getLoginCredentials();

                if(Auth::attempt($credentials)){
                    return Redirect::route("user/profile");

    }

    public function logout()

GroupController

class GroupController extends \BaseController {

    public function indexAction()
    {
        return View::make("group/index", [
            "groups" => Group::all()
        ]);
    }

    public function addAction()
    {
        $form = new GroupForm();

        if($form->isPosted()){
            if($form->isValidForAdd()){
                Group::create([
                    "name" => Input::get("name")
                ]);

                return Redirect::route("group/index");
            }

            return Redirect::route("group/add")->withInput([
                "name" => Input::get("name"),
                "errors" => $form->getErrors()
            ]);
        }

        return View::make("group/add", [
            "form" => $form
        ]);
    }

    public function editAction()
    {
        $form = new GroupForm();

        $group = Group::findOrFail(Input::get("id"));
        $url = URL::full();

        if($form->isPosted()){
            if($form->isValidForEdit()){
                $group->name = Input::get("name");
                $group->save();

                $group->users()->sync(Input::get("user_id", []));
                $group->resources()->sync(Input::get("resource_id", []));

                return Redirect::route("group/index");
            }

            return Redirect::to($url)->withInput([

            ]);
        }

        return View::make("group/edit", [
            "form" => $form,
            "group" => $group,
            "users" => User::all(),
            "resources" => Resource::where("secure", true)->get()
        ]);
    }

    public function deleteAction()
    {
        $form = new GroupForm();

        if($form->isValidForDelete()){
            $group = Group::findOrFail(Input::get("id"));
            $group->delete();
        }

        return Redirect::route("group/index");
    }
}

但我不确定如何修复它，特别是因为我正在学习教程。
