Facebook登录不在Laravel中

Question

我想使用以下代码在Laravel中使用facebook创建登录模块，但问题是会话变量是空白的，因此它不会重定向到主页。点击facebook的登录按钮后，我的程序控制移动到以下其他部分return Response::make('Not loggedin', 400);，然后我看到

jquery.min.js：4在我的浏览器控制台中获取http://localhost/Script/login/fb 400（错误请求）。

我是Laravel的新手。任何帮助/建议将受到高度赞赏。

  

UserController.php

public function loginWithFb() {


$redirectUrl = Input::get('redirect_url');
$facebookBaseConfig = Config::get('facebook');
$config = app('siteConfig');
$facebookConfig = $config['main']['social']['facebook'];
$facebookConfig['appId'] = empty($facebookConfig['appId']) ? '' : $facebookConfig['appId'];
$facebookConfig['secret'] = empty($facebookConfig['secret']) ? '' : $facebookConfig['secret'];
FacebookSession::setDefaultApplication($facebookConfig['appId'], $facebookConfig['secret']);
$helper = new FacebookJavaScriptLoginHelper();
$session = null;

function getUserDataFromFb($session){
    $request = new FacebookRequest($session, 'GET', '/me');
    $response = $request->execute();
    $graphObject = $response->getGraphObject()->asArray();
    return $graphObject;
}

try {
    $session = $helper->getSession();
} catch(FacebookRequestException $ex) {
    // When Facebook returns an error
} catch(\Exception $ex) {
    // When validation fails or other local issues
}


if(Request::ajax()) {

    if ($session) {
      // Logged in.
        $uid = $session->getUserId();
        $accessToken = $session->getToken();
        $profile = Profile::whereUid($uid)->first();
        if (empty($profile)) {
            $me = getUserDataFromFb($session);  
            $user = new User;
            $user->name = $me['first_name'].' '.$me['last_name'];
            $user->email = $me['email'];
            $user->photo = 'https://graph.facebook.com/'.$uid.'/picture?type=large';

            $user->save();

            $profile = new Profile();
            $profile->uid = $uid;
            //$profile->username = $me['username']; //Username not available in the new Facebook API
            $profile->access_token = $accessToken;
            $profile = $user->profiles()->save($profile);

        }
        else {
            $profile->access_token = $accessToken;
            $profile->save();
        }
        $user = $profile->user;
        Auth::login($user);
        return Response::json(array('user' => $user));
    } else {
        return Response::make('Not loggedin', 400);
    }
} else{
    if ($session) {
        if($redirectUrl) {
            return Redirect::to($redirectUrl);
        } else{
            return Redirect::route('home');
        }
    }
    return Redirect::route('login');
