为什么我不能获取数据时，用户设置是私人的位置等（Facebook的PHP SDK）

Question

首先对于这个noobish问题抱歉，我想从Facebook获取数据。我为我的网站设置了facebook应用程序，获取数据正在工作，但是当我将位置（Facebook信息）设置为私人时，返回的数据不包含位置数据。

这里是模型

class Facebook_model extends CI_Model { 

public function __construct() 
{ 
    parent::__construct(); 

    $config = array(
        'appId' => 'APP_ID', 
        'secret' => 'SECRET', 
        'fileUpload' => true, 
        ); 

    $this->load->library('Facebook', $config); 

    $user = $this->facebook->getUser(); 
    $profile = null; 
    if($user) 
    { 
     try 
     { 
      $profile = $this->facebook->api("/me", 'get'); 
     }catch(FacebookApiException $e) 
     { 
      error_log($e); 
      $user = null; 
     } 
    } 

    $fb_data = array(
     'me' => $profile, 
     'uid' => $user, 
     'loginUrl' => $this->facebook->getLoginUrl(
      array(
        'scope' => 'email,publish_stream,user_about_me,user_checkins,publish_stream,friends_about_me', 
        'redirect_uri' => base_url() . 'index.php/welcome/topsecret/' 
       ) 
      ), 
     'logoutUrl' => $this->facebook->getLogoutUrl() 
    ); 

    $this->session->set_userdata('fb_data', $fb_data); 

     } 

这里是我的虚拟帐户的输出，隐私设置为公开，

Answer 1

尝试增加“USER_LOCATION”到$ fb_data ['loginUrl ']['范围']。下面是您可以在FB API使用所有的权限列表：https://developers.facebook.com/docs/authentication/permissions/

Answer 2

1. 采取用户和好友权限在Facebook应用程序的USER_LOCATION

2. 使用

   $ PARAM =阵列（ '范围'= >'email，user_location，user_birthday，offline_access'， 'redirect_uri'=> base_url（） ）; 重定向（$ this-> fb_connect-> getLoginUrl（$ param））;
