Hey If you are using laravel 5.2, this is worked for me.
Put your controllers in 'web' middleware. like,
Route::group(['middleware' => 'web'], function() {
Route::get('google', 'Auth\AuthController#redirectToProvider');
Route::get('google/callback', 'Auth\AuthController#handleProviderCallback');
});
and Make sure Kernel file has middleware classes registered.
/**
* The application's route middleware groups.
*
* #var array
*/
protected $middlewareGroups = [
'web' => [
\Perkweb\Http\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\Perkweb\Http\Middleware\VerifyCsrfToken::class,
],
'api' => [
'throttle:60,1',
],
];
