Laravel 5.5 - 未找到“Facebook \ Helpers \ Session”类

Question

Trying to get Facebook PHP SDK working on Laravel 5.5, with local XAMPP installation (hostname: laravel.dev)

Facebook application is set-up correctly, and with the Facebook login, it's possible to login. $fbobject->getRedirectLoginHelper() returns apparently successful, however the subsequent attempt to get the accessToken results in:

Error:

 Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_ERROR) Class 'Facebook\Helpers\Session' not found

Controller Code:

    <?php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Session;
use Facebook\Facebook;

class HomeController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        //$this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $fb = new \Facebook\Facebook([
        'app_id' => '11111111111111111',
        'app_secret' => '1111111111111111111111111111111',
        'allowSignedRequest' => false,
        'default_graph_version' => 'v2.10',
        'default_access_token' => '1111111111111|1111111111111111111111'
        ]);

        $helper = $fb->getRedirectLoginHelper();
        $accessToken = $helper->getAccessToken();

        $permissions = ['email']; // Optional permissions
        $loginUrl = $helper->getLoginUrl('http://laravel.dev/home', $permissions);

        $passdata = array(
                'loginUrl' => $loginUrl,
                );

        return view(('home.test'), $passdata);

    }
}

I also tried the SammyK Laravel installation, and that also produces the same error.

I'm not sure but you may use this

use Facebook\FacebookSession;

Reference here.
