LinkedIn PHP API不設置訪問令牌笨

這是我第一次與LinkedIn的API的工作，我試圖按照官方文檔在這個例子：LinkedIn PHP API不設置訪問令牌笨

[http://developer.linkedin.com/documents/code-samples][1]

我已經重構同樣的程序代碼到所謂Auth一個笨控制器類：我使用

<?php if (!defined('BASEPATH')) die(); 

class Auth extends CI_Controller 
{ 

    public function __construct() 
    { 

     parent::__construct(); 

     define('API_KEY',  $this->config->item('key')); 
     define('API_SECRET', $this->config->item('secret')); 
     define('REDIRECT_URI', 'http://' . $_SERVER['SERVER_NAME'] . ':8000/auth'); 
     define('SCOPE',  'r_basicprofile r_emailaddress rw_groups'); 

    } 

    public function index() 
    { 
     var_dump($this->session->all_userdata()); 
     if (!empty($this->session->userdata('state'))) { 
     $user = $this->fetch('GET', '/v1/people/~:(firstName,lastName)'); 
     print "Hello $user->firstName $user->lastName."; 
     } else { 
     // $this->session->sess_destroy(); 
     echo anchor('auth/oauth', 'Sign in with Linkedin'); 
     } 

    } 


    public function oauth() 
    { 
     // 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 ($this->session->userdata('state') == $_GET['state']) { 
       // Get token so you can make API calls 
       $this->getAccessToken(); 
      } else { 
       // CSRF attack? Or did you mix up your states? 
       exit; 
      } 
     } else { 
      if ((empty($this->session->userdata('expires_at'))) || (time() > $this->session->userdata('expires_at'))) { 
       // Token has expired, clear the state 
       $this->session->sess_destroy(); 
      } 
      if (empty($this->session->userdata('access_token'))) { 
       echo "here I am"; 
       // Start authorization process 
       $this->getAuthorizationCode(); 
      } 
     } 

    } 

    protected function getAccessToken() { 
     $params = array('grant_type' => 'authorization_code', 
         'client_id' => API_KEY, 
         'client_secret' => API_SECRET, 
         'code' => $_GET['code'], 
         'redirect_uri' => REDIRECT_URI, 
       ); 

     // Access Token request 
     $url = 'https://www.linkedin.com/uas/oauth2/accessToken?' . http_build_query($params); 

     // Tell streams to make a POST request 
     $context = stream_context_create(
         array('http' => 
          array('method' => 'POST', 
          ) 
         ) 
        ); 

     // Retrieve access token information 
     $response = file_get_contents($url, false, $context); 
     // Native PHP object, please 
     $token = json_decode($response); 

     // Store access token and expiration time 

     // $_SESSION['access_token'] = $token->access_token; // guard this! 
     // $_SESSION['expires_in'] = $token->expires_in; // relative time (in seconds) 
     // $_SESSION['expires_at'] = time() + $_SESSION['expires_in']; // absolute time 

     $this->session->set_userdata('access_token', $token->access_token); 
     $this->session->set_userdata('expires_in', $token->expires_in); 
     $this->session->set_userdata('expires_at', time() + $this->session->userdata('expires_in')); 

     return true; 
    } 

    protected function getAuthorizationCode() { 
     $params = array('response_type' => 'code', 
         'client_id' => API_KEY, 
         'scope' => SCOPE, 
         'state' => uniqid('', true), // unique long string 
         'redirect_uri' => REDIRECT_URI, 
       ); 

     // Authentication request 
     $url = 'https://www.linkedin.com/uas/oauth2/authorization?' . http_build_query($params); 

     // Needed to identify request when it returns to us 
     // $_SESSION['state'] = $params['state']; 
     $this->session->set_userdata('state', $params['state']); 

     // Redirect user to authenticate 
     redirect($url); 
    } 


    protected function fetch($method, $resource, $body = '') { 
     $params = array('oauth2_access_token' => $this->session->userdata('access_token'), 
         'format' => 'json', 
       ); 

     // Need to use HTTPS 
     $url = 'https://api.linkedin.com' . $resource . '?' . http_build_query($params); 
     // Tell streams to make a (GET, POST, PUT, or DELETE) request 
     $context = stream_context_create(
         array('http' => 
          array('method' => $method, 
          ) 
         ) 
        ); 


     // Hocus Pocus 
     $response = file_get_contents($url, false, $context); 

     // Native PHP object, please 
     return json_decode($response); 
    } 

    public function logout() 
    { 
     $_SESSION = array(); 
     $this->load->view('comment_index'); 
    } 

}

數據庫來存儲會話，我期待access_token存儲在我的序列化的字段中的值的一個叫user_data 。但我什麼也沒得到。當前會話的輸出是：

array (size=5) 
    'session_id' => string '1dfcbc17bf0346424726c7cace63501b' (length=32) 
    'ip_address' => string '`127.0.0.1`' (length=9) 
    'user_agent' => string 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:25.0) Gecko/20100101 Firefox/25.0' (length=81) 
    'last_activity' => int 1386687134 
    'user_data' => string '' (length=0)

我不明白爲什麼LinkedIn是不是給我回令牌存儲。由於redirect_url，我無法正確調試此代碼。到目前爲止，什麼工作是：

用戶重定向到授權窗口，其中烏爾：https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=75y11f289134ga&scope=r_basicprofile+r_emailaddress+rw_groups&state=52a72cc4e54f36.03304050&redirect_uri=http%3A%2F%2F127.0.0.1%3A8000%2Fauth
用戶被重定向到auth動作，而不與此網址的任何錯誤：http://127.0.0.1:8000/auth?碼= AQTWPFJqnZlBZmFByb3Vbjkf4jtNvn8C7atg5iM6iXFW3ON_SrM3uJ9h8AiF1RbMjgGt_NpDq4cTPL1qw8uNiA_vsOv1H3lpxu0IxHVx_sa9rDAinbo & state = 52a72d109261d4.41607693

但是我的個人資料數據在哪裏？如何以及在哪裏進行api調用以檢索配置文件數據？請幫忙

我在Codeigniter中也是這樣做的。

以下是獲取Auth用戶配置文件的過程。

爲LinkedIn

創建庫

class Linkedin { 

    function __construct(){ 

    } 

    public function getAuthorizationCode() { 
     $params = array('response_type' => 'code', 
      'client_id' => API_KEY, 
      'scope' => SCOPE, 
      'state' => uniqid('', true), // unique long string 
      'redirect_uri' => REDIRECT_URI, 
     ); 
     // Authentication request 
     $url = 'https://www.linkedin.com/uas/oauth2/authorization?' . http_build_query($params); 

     // Needed to identify request when it returns to us 
     $_SESSION['state'] = $params['state'];

} 

/* End of file Linked.php */ 
/* Location: ./application/libraries/linkedin.php */

把你所有的常量的東西，在confin/constants.php

define('API_KEY', 'Put Yoour API_KEY here'); 
define('API_SECRET', 'Put Yoour API_SECRET here'); 
define('REDIRECT_URI', 'Put Yoour REDIRECT_URI here'); 
define('SCOPE', 'r_fullprofile r_emailaddress rw_nus r_contactinfo r_network');

現在控制器

class Profile extends CI_Controller { 

    function __construct() { 
     parent:: __construct(); 
     $this->load->library('linkedin'); // load library 
     session_name('linkedin'); 
     session_start(); 
    } 

    // linkedin login script 
    function profile() { 
     // OAuth 2 Control Flow 
     if (isset($_GET['error'])) { 
      // LinkedIn returned an error 
      // load any error view here 
      exit; 
     } elseif (isset($_GET['code'])) { 
      // User authorized your application 
      if ($_SESSION['state'] == $_GET['state']) { 
       // Get token so you can make API calls 
       $this->linkedin->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 
       $this->linkedin->getAuthorizationCode(); 
      } 
     } 
     // define the array of profile fields 
     $profile_fileds = array(
      'id', 
      'firstName', 
      'maiden-name', 
      'lastName', 
      'picture-url', 
      'email-address', 
      'location:(country:(code))', 
      'industry', 
      'summary', 
      'specialties', 
      'interests', 
      'public-profile-url', 
      'last-modified-timestamp', 
      'num-recommenders', 
      'date-of-birth', 
     ); 
     $profileData = $this->linkedin->fetch('GET', '/v1/people/~:(' . implode(',', $profile_fileds) . ')'); 
     if ($profileData) { 
      // save profile or do whatever you want 
     } else { 
      // linked return an empty array of profile data 
     } 
    } 

}

非常感謝您貢獻此代碼。我會對它進行測試，然後馬上回到你身邊。 –

我用這個代碼..但是當我試圖存儲$ profileData在sesion它不起作用..請幫助 – Brett

@Brett你能分享你的代碼嗎？ – DMH
