通过laravel 4中的Facebook API登录时出现错误消息未定义电子邮件

给出错误消息未定义的电子邮件。以及当我想插入lastname时，给出相同错误未定义的lastname

请帮助我。我第一次在laravel中实现API

请给我发送任何与Facebook和谷歌登录Laravel4.2相关的链接

 Route::get('login/fb', function(){ $facebook = new Facebook(Config::get('facebook'));
$params = array(
    'redirect_uri' => url('/login/fb/callback'),
    'scope' => 'email',
);
return Redirect::away($facebook->getLoginUrl($params));});

---

}))

您应该明确请求所需的字段：

$me=$facebook->api（'/me？fields=电子邮件、姓氏、名）

---

你得到的

$me

正确吗？是的，我得到的$me正确$me=$facebook->api（'/me'）；因为我使用Facebook connect作为Javascript应用程序，我也遇到了同样的问题。我使用的范围是：“public_profile，email”，用于获取用户电子邮件：FB.api（'/me？fields=email'，function（response）{var email=response.email；}）；

Route::get('login/fb/callback', function() {


$code = Input::get('code');

if (strlen($code) == 0) return Redirect::to('/')->with('message', 'There was an error communicating with Facebook');

$facebook = new Facebook(Config::get('facebook'));
$uid = $facebook->getUser();

if ($uid == 0) return Redirect::to('/')->with('message', 'There was an error');

$me = $facebook->api('/me');


$profile = Profile::whereUid($uid)->first();
if (empty($profile)) {

    $user = new User;
   $user->firstname = $me['name'];
    $user->email=$me['email'];

    $user->pic = 'https://graph.facebook.com/'.$me['id'].'/picture?type=large';

    $user->save();

    $profile = new Profile();
    $profile->uid = $uid;
    $profile->username = $me['id'];
    $profile = $user->profiles()->save($profile);
}

$profile->access_token = $facebook->getAccessToken();
$profile->save();

$user = $profile->user;

Auth::login($user);

return Redirect::to('index')->with('message', 'Logged in with Facebook');
