php - facebook getlogin 网址无效

Question

我想让用户通过 facebook 登录。我正在使用这段代码:

  <?php

    require 'include/facebook.php';
    require 'include/fbconfig.php';
    require 'include/user.php';

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

    $session = $facebook->getSession();

    if (!empty($session)) {
        # Active session, let's try getting the user id (getUser()) and user info (api->('/me'))
        try {
            $uid = $facebook->getUser();
            $user = $facebook->api('/me');
        } catch (Exception $e) {

        }

        if (!empty($user)) {
            # User info ok? Let's print it (Here we will be adding the login and registering routines)
            echo '<pre>';
            print_r($user);
            echo '</pre><br/>';
            $username = $user['name'];
            $user = new User();
// check user method insert login information to my database and return the result
            $userdata = $user->checkUser($uid, 'facebook', $username);
            if(!empty($userdata)){
                session_start();
                $_SESSION['id'] = $userdata['id'];
                $_SESSION['oauth_id'] = $uid;
                $_SESSION['username'] = $userdata['username'];
                $_SESSION['oauth_provider'] = $userdata['oauth_provider'];
                header("Location: test.php");
            }
        } else {
            # For testing purposes, if there was an error, let's kill the script
            die("There was an error.");
        }
    } else {
        # There's no active session, let's generate one
        $params = array(
         'scope' => 'email'
      );
        $login_url = $facebook->getLoginUrl($params);
        header("Location: " . $login_url);
    }
    ?>

当我运行这个页面时出现问题，它将我重定向到 facebook 主页(到我的帐户)。

拜托，有什么想法吗？？
您的帖子没有太多上下文来解释代码部分；请更清楚地解释您的情况。

您使用的是最新的 PHP SDK 吗？从 here 获取最新的 SDK , 然后重试..

[编辑]

将所有对 getSession() 的引用替换为 getUser()

例子:

$session = $facebook->getSession();

它应该说:

$session = $facebook->getUser();

引用:Upgrade to PHP SDK v3.0.0
