Question

我想让用户通过Facebook登录。我正在使用此代码：

  <?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);
    }
    ?>

运行此页面时的问题，它会将我重定向到Facebook主页（到我的帐户）。

请，任何想法??
你的帖子没有太多的上下文来解释代码部分;请更清楚地解释一下你的情景。

Answer 1

您使用的是最新的PHP SDK吗？从here获取最新的SDK，然后重试..

<强> [EDITED]

将所有对getSession()的引用替换为getUser()

示例：

$session = $facebook->getSession();

它应该说：

$session = $facebook->getUser();

参考：Upgrade to PHP SDK v3.0.0

Answer 2

这肯定会起作用 -

$user=NULL ;
$user       = $facebook->getUser();
if($user)
{
    $loginUrl   = $facebook->getLoginUrl(
       array(
              'scope'         => 'email',
              'redirect_uri'  => 'https://appurl'
            )
    );
}

Answer 3

如果您已登录，则不会进入登录页面。

尝试注销并检查您的代码是否有效。
