php - How to authenticate user manually from cookie in laravel 5? -

i working on websockets, using rachet. whenever user tries establish connection, need authenticate. backend uses laravel 5 http authentification.

my server code :

    public function onopen(connectioninterface $conn, requestinterface $request = null) {        if (null === $request) {             throw new \unexpectedvalueexception('$request can not null');        }        $cookie = $request->getcookie('laravel_session');  //do authentification cookie if possible 

i tried use laravel

auth::user() 

i got following error :

call member function user() on null

whenever try connect websockets browser, use ws protcol , rachets server, laravel routes never getting called. reason getting error when try use auth::user() ?

can use cookie verify if user logged in? there other solutions? security risks involved?

i got myself.

require_once getcwd() . '/bootstrap/autoload.php';         $app = require getcwd() . '/bootstrap/app.php';          $kernel = $app->make(\illuminate\contracts\http\kernel::class); //        var_dump('kernel booted successfully');          $response = $kernel->handle(             $request = \illuminate\http\request::capture()         );  //        var_dump('response object created');  //        var_dump('decrypting cookie : '); //        var_dump($cookie);         $id = $app['encrypter']->decrypt($cookie);  //        var_dump('id decrypted : '.$id);         $app['session']->driver()->setid($id);         $app['session']->driver()->start();          $user = $app['auth']->check();         //if not logged in         if( $user == false ){             return false;         }else{              //return instance of app             return $app;             //to user details: $app['auth']->user()         }
