Facebook PHP SDK 4.0 Login with Lumen -

i writing small application i'm trying facebook information, can't manage authentication work.

at first i've setup appserviceprovider with:

facebooksession::setdefaultapplication(static::app_id, static::app_secret); 

then in view have button goes auth url.
auth route using homecontroller@index, contains following:

public function auth(request $request) {     $helper = new facegroupredirectloginhelper($request->url());      if($session = $helper->getsessionfromredirect()) {         dd($session);     }      return redirect($helper->getloginurl()); } 

i've created own facebookredirectloginhelper extends base class of facebook. has following methods, leverage lumen session implementation:

protected function storestate($state) {     session::put(static::session_key, $state); }  protected function loadstate() {     return $this->state = session::get(static::session_key, null); } 

this code not working somehow, i've seen people doing on internet well. wrong? session null.

facebook sdk v5 laravel works fine lumen have change routing ... here how configure , use laravelfacebooksdk lumen

to use first

{     "require": {         "sammyk/laravel-facebook-sdk": "~3.0"     } } 

then in bootstrap/app.php of lumen add

// facebook sdk provider $app->register('sammyk\laravelfacebooksdk\laravelfacebooksdkserviceprovider'); 

then pubish config ( make sure have config folder setup lumen , default isn’t there )

$ php artisan vendor:publish --provider="sammyk\laravelfacebooksdk\laravelfacebooksdkserviceprovider" 

the main step configure service provider , laravel facebook sdk default laravelfacebooksdk.php , laravelurldetectionhandler.php uses illuminate\routing\urlgenerator . find files in vendor src folder replace laravel\lumen\routing\urlgenerator . , done . ( careful editing vendor src files are not recommended because overwritten next time call composer update or new version appears on composer repository . quick fix testing . fork it, make own repo or find way )

then wil able use laravelfacebooksdk in lumen

$app->get('/user', function(sammyk\laravelfacebooksdk\laravelfacebooksdk $fb){      // basic info on user facebook.     try {          $token = "your-access-token-here";          $fb->setdefaultaccesstoken($token);          $response = $fb->get('/me?fields=id,name,email');     } catch (facebook\exceptions\facebooksdkexception $e) {         dd($e->getmessage());     }      // convert response `facebook/graphnodes/graphuser` collection     $facebook_user = $response->getgraphuser();      var_dump($facebook_user);  });
