到目前为止，我已将其设置为检索基本用户信息，没有任何扩展。我也尝试获取用户电子邮件，但没有成功。这是我得到的：

   $facebook = new Facebook(array(
            'appId' => APP_ID,
            'secret' => APP_SECRET,
            'cookie' => true,

        ));

$session = $facebook->getSession();

if (!empty($session)) {
    try {
    $params = array(
      'scope' => 'email',
      'redirect_uri' => 'https://www.dormduels/splash_test'
    );

    $loginUrl = $facebook->getLoginUrl($params);
        $uid = $facebook->getUser();

         $access_token = $facebook->getAccessToken();

        echo $access_token;
        $user = $facebook->api('me?fields=name,first_name,last_name,username,email&access_token='.$access_token);
        echo "<pre>";
        print_r($user);
        exit();

问题是。它显示的 getAccessToken 在 facebooks 图形浏览器中测试时，不显示扩展数据，如电子邮件，仅显示基本数据。如何请求启用更多权限的访问令牌？

您需要通过以下方式之一请求扩展权限，即此处的“电子邮件”：

  1. php SDK

    使用 sdk 对象的getLoginUrl()方法，并在“范围”中指定您需要的扩展权限，并将用户重定向到其返回值，您还需要在Facebook 应用程序的管理页面中添加域和站点 url . 这是一个例子：

    define('APP_ID', 'TODO FILL IT WITH YOURS');
define('APP_SECRET', 'TODO FILL IT WITH YOURS');

require_once 'facebook.php';

function redirect_to_login($fb){
    $login_url = $fb->getLoginUrl(array(
        'scope' => 'email',
    ));
    header('Location: '.$login_url);
    exit;
}

$fb = new Facebook(array(
    'appId' => APP_ID,
    'secret' => APP_SECRET,
    'cookie' => true,
));

$uid = $fb->getUser();
if (!$uid || !check_perms($fb, $uid, array('email'))) { // see check_perms below
    // send users to login/auth page if they are not logged in, 
    // or not installed the app, 
    // or don't have all the perms we need
    redirect_to_login($fb);
}

try {
    $me = $fb->api('/me');
    var_dump($me);
} catch (Exception $e) {
    redirect_to_login($fb);
}

  2. js SDK

    使用FB.login()函数在第二个参数中请求您需要的扩展权限。

有关整个身份验证过程的详细信息，请参阅此页面。

如果你想检查当前用户是否拥有你想要的所有权限，你可以像这样使用FQL：

function check_perms($facebook, $uid, $perms = array()) {

    $perms_str = join(' = 1 and ', $perms).' = 1';
    $query = "select uid from permissions where uid = '".$uid."' and ".$perms_str;

    try {
        $row = $facebook->api(array(
            'method' => 'fql.query',
            'query'  => $query,
        ));
        return $row && $row[0]['uid'] == $uid;
    } catch (Exception $e) {
        return false;
    }
}

注意： 您的php sdk版本可能已经过时，getSession() 方法已被弃用，取而代之的是 getUser() / getAccessToken()

在我这边，我这样做：

// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
  'appId'  => FB_API_KEY,
  'secret' => FB_API_SECRET,
));

// Get User ID
$fb_user = $facebook->getUser();

// We may or may not have this data based on whether the user is logged in.
//
// If we have a $fb_user id here, it means we know the user is logged into
// Facebook, but we don't know if the access token is valid. An access
// token is invalid if the user logged out of Facebook.
if ($fb_user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $fb_user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $fb_user = null;
  }
}

// Login or logout url will be needed depending on current user state.
if ($fb_user) {
    $fb_loggedin = true;
} else {
    $fb_loggedin = false;
    $fb_loginUrl = $facebook->getLoginUrl(array(
        'scope' => 'email,user_location',
        'redirect_uri' => 'http://'.$_SERVER['HTTP_HOST'].'/debut_'.($lang == 'fr' ? 'fr' : 'eng').'.php'
    ));
}

getLoginUrl 中的 SCOPE 是您要查看的内容，您可以在开发人员网站上看到所有不同的权限：

Try following:
$facebook = new Facebook(array(
    'appId' => APP_ID,
    'secret' => APP_SECRET,
    'cookie' => true,
));

 public function login() {
        $loginUrl= $facebook->getLoginUrl(array('scope' => 'email',
                    'redirect_uri' => 'your redirectUri',
                    'display' => 'popup'
                ));
       header("Location:$loginUrl");
    }
public function fUserInfo() {
        $access_token = $facebook->getAccessToken();
        //check permissions list
        $permissions_list = $facebook->api('/me/permissions', 'GET', array('access_token' => $access_token));
        $permissions_needed = array('email');
        foreach ($permissions_needed as $perm) {
            if (!isset($permissions_list['data'][0][$perm]) || $permissions_list['data'][0][$perm] != 1) {
                login();
            }
        }
        $user = $facebook->getUser();
        if ($user) {
            try {
                $userInfo = $facebook->api("/$user");
            } catch (FacebookApiException $e) {
                Config::getLogger()->debug($e->getMessage());
            }
        }
        print_r($userInfo);
    }
