LinkedIn API獲得第一學位連接和公司名稱，職位和行業？

Question

我使用這段代碼訪問LinkedIn API，它的工作原理非常完美，但它只獲取名字，姓氏，標題和電子郵件等詳細信息。

我想獲得用戶的連接，公司名稱，公司類型，公司大小，職位和行業。

如何通過LinkedIn API獲取這些詳細信息？

<?php 
// Change these 
define('API_KEY',  [api_key]); 
define('API_SECRET', [api_secret]); 
define('REDIRECT_URI', 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['SCRIPT_NAME']); 
define('SCOPE',  'r_fullprofile r_emailaddress rw_nus r_network'); 

// You'll probably use a database 
session_name('linkedin'); 
session_start(); 

// OAuth 2 Control Flow 
if (isset($_GET['error'])) { 
    // LinkedIn returned an error 
    print $_GET['error'] . ': ' . $_GET['error_description']; 
    exit; 
} elseif (isset($_GET['code'])) { 
    // User authorized your application 
    if ($_SESSION['state'] == $_GET['state']) { 
     // Get token so you can make API calls 
     getAccessToken(); 
    } else { 
     // CSRF attack? Or did you mix up your states? 
     exit; 
    } 
} else { 
    if ((empty($_SESSION['expires_at'])) || (time() > $_SESSION['expires_at'])) { 
     // Token has expired, clear the state 
     $_SESSION = array(); 
    } 
    if (empty($_SESSION['access_token'])) { 
     // Start authorization process 
     getAuthorizationCode(); 
    }

對於1度連接，您只能檢索基本配置文件字段，您可以像這樣使用。僅供參考http://developer.linkedin.com/documents/connections-api

$user = fetch('GET', 'http://api.linkedin.com/v1/people/~/connections: 
    (id,first-name,last-name,location:(name),picture-url)');
