Laravel 5.1身份验证视图

我使用的是Laravel5.1和模块化软件包。 在控制器中，我使用以下登录方法：

public function postLogin(Request $request)
{   
   $email = $request->input('email');
   $password = $request->input('password');

   if (Auth::attempt(['email' => $email, 'password' => $password])) {
       return redirect()->intended('admin/dashboard');
   }

   return redirect('/login')->withErrors([
   'email' => 'These credentials do not match our records.']);
}

我的路线：

Route::group(array('module' => 'Admin', 'namespace' => 'App\Modules\Admin\Controllers'), function() {

Route::get('admin/dashboard', [
    'middleware' => 'auth',
    'uses' => 'AdminController@index'
]);
}}

我的控制器：

public function index()
{
    return view("Admin::index");
}

我的中间件/身份验证：

public function handle($request, Closure $next)
  {
     if ($this->auth->guest()) {
         if ($request->ajax()) {
             return response('Unauthorized.', 401);
         } else {
             return redirect()->guest('auth/login');
         }
     }

     return $next($request);
 }

这可以工作，并在登录后将我重定向到索引视图。 当用户未登录时，仍然可以通过访问url:localhost/admin/dashboard来访问索引视图

如何将用户重定向到自定义页面，该页面向用户显示一个错误，即当用户未登录时，无法访问url localhost/admin/dashboard

有什么想法吗？多谢各位

    The issue is with your route the middleware should be at the top level as soon as you hit the controller it should redirect if not authenticated

    Route::group(['middleware'=>'auth','module' => 'Admin', 'namespace' => 'App\Modules\Admin\Controllers'], function()
    {
        Route::get('admin/dashboard', ['uses' => 'AdminController@index']);
    });

secondly if you want to redirect user to a custom page you can do this 

public function redirectUnAuthenticateUser()
{

\Session::flash('login_error', 'Kindly login before you can access this page');
//create a view that user would be redirected to
return view('session.unauthenticated') ;
}


and the change your auth function to below 

public function handle($request, Closure $next)
  {
     if ($this->auth->guest()) {
         if ($request->ajax()) {
             return response('Unauthorized.', 401);
         } else {
return redirect()->route('you-custom-rout-name-matching-above-function');
         }
     }

     return $next($request);
 }

and on your view you can get the value of the flash message
