Laravel 5 check whether a user is logged in

问题:

I am new to Laravel 5 and trying to understand its Auth process. I want to prevent user to reach some of my pages unless the user is not logged in. Trying to make it with Route:filter but it does not work. What i have done wrong ?

Route::filter('/pages/mainpage', function()
{
    if(!Auth::check()) 
    {
        return Redirect::action('PagesController@index');
    }
});

回答1:

You should use the auth middleware. In your route just add it like this:

Route::get('pages/mainpage', ['middleware' => 'auth', 'uses' => 'FooController@index']);

Or in your controllers constructor:

public function __construct(){
    $this->middleware('auth');
}

回答2:

you can do this directly in your blade code by this way

@if (!Auth::guest())
        do this 
@else
        do that
@endif

回答3:

if you want authentication middleware for single route then

// Single route

Route::get("/awesome/sauce", "AwesomeController@sauce", ['middleware' => 'auth']);

if you want auth middlesware on multiples routes then use :

// Route group

Route::group(['middleware' => 'auth'], function() {
// lots of routes that require auth middleware
});

U can use midlleware in colntroller

All actions in controller require to be logged in

   public function __construct()
    {
        $this->middleware('auth');
    }

Or u can check it in action

public function create()
    {
        if (Auth::user()) {   // Check is user logged in
            $example= "example";
            return View('novosti.create')->with('example', $example);

        } else {
            return "U cant access here!";
        }
    }

also u can use it on route

Route::get('example/index', ['middleware' => 'auth', 'uses' => 'example@index']);

Auth::check()
