我正在使用 Facebook javascript sdk 和 php sdk 将用户登录到我的网络应用程序。使用javascript,我可以登录/退出工作,并且可以获得登录用户的公共Facebook详细信息。

但是,当使用 php 时,我没有得到用户的 facebook 详细信息。为了给你一些关于应用程序的信息,当我导航到包含表单的某个页面时,代码会检查他们是否登录。如果没有,他们会得到一个 LoginUrl 链接。登录后,我有 $user_id,所以现在用户可以使用该表单,但在提交表单时,我没有将他们的 Facebook 详细信息保存在 MySQL 数据库中。有人对我应该做什么有建议吗?我肯定有 $user_id,因为只有在我有 $user_id 时才会显示表单。

我的代码基于https://developers.facebook.com/docs/reference/php/facebook-api/

<?php
require 'facebook.php';
//create application instance
$config = array(
'appId' => '**************',
'secret' => '****************************',
'cookie' => true);
$facebook = new Facebook($config);
$user_id = $facebook->getUser(); 
?>

//Page containing form
<div data-role="page" id="postAJourney" data-add-back-btn="true" data-back-btn-text="back" data-rel="back" data-direction="reverse" data-transition="flip" data-theme="b" >
    <div data-role="header"  data-position="fixed">
       <h1>Post A Journey</h1>
    </div>

    <div data-role="content">
       <?php if ($user_id): ?>
       <form action="add_journey.php" method="post" id="postAJourneyForm">
       <?php
       try
       {
           $access_token = $facebook->getAccessToken();
       $param_token = array('access_token' => $access_token); 
       //Proceed knowing you have a logged in user who's authenticated.
       $user_profile = $facebook->api('/me','GET',$param_token);
       echo "Name: " . $user_profile['name'];
       // store session data
       $_SESSION['fb_id'] = $user_profile['id'];
       $_SESSION['fb_name'] = $user_profile['name'];
       $_SESSION['fb_first_name'] = $user_profile['first_name'];
       $_SESSION['fb_last_name'] = $user_profile['last_name'];
       $_SESSION['fbImg'] = "https://graph.facebook.com/".$user_profile['id']."/picture";
    $_SESSION['fbLink'] = "https://www.facebook.com/".$user_profile['name'];
       }
       catch(FacebookApiException $e)
       {
       // If the user is logged out, you can have a 
       // user ID even though the access token is invalid.
       // In this case, we'll get an exception, so we'll
       // just ask the user to login again here.
       $login_url = $facebook->getLoginUrl(); 
       error_log($e->getType());
       error_log($e->getMessage());
       }
       ?>

       //jQuery Mobile Form would be here

 <?php else: ?>
 <?php // No user, print a link for the user to login
$login_url = $facebook->getLoginUrl(array(
'scope' => 'email',
'redirect_uri' => "http://localhost/share/#postAJourney"
));
 ?>
 <div>
     Login using OAuth 2.0 handled by the PHP SDK:
     <a href="<?php echo $login_url; ?>">Login with Facebook</a>
 </div>
 <?php endif ?>

/*您需要用户访问令牌,然后将该令牌作为参数传递给 Facebook /me API,然后您可以获得 Facebook 用户的登录信息。你需要从范围内的用户那里传递你想要的权限范围。为了检索用户访问令牌,你可以像这样使用 */

$loginUrl = $facebook->getLoginUrl(array('scope' => 'manage_pages','redirect_uri'=>'你的 url'));

/* 制作 oauth url 并在其中传递范围以允许用户访问 Facebook 誓言页面以获得许可 从 facebook 重定向获取访问令牌,它将在请求中为您提供 */

$access_token = $facebook->getAccessToken();

$param_token = array('access_token' => $access_token);

$user_profile = $facebook->api('/me'); //替换为该行

$user_profile = $facebook->api('/me','GET',$param_token);
