我在使用 Facebook 登录和 PHP 时遇到问题。
下面的文件似乎导致了这个问题。一切正常,直到我成功登录 Facebook 并且浏览器在重定向回此文件时最终抛出无限重定向错误。最后一个 else 语句总是被执行导致循环......
有任何想法吗?提前致谢!
<?php
require 'facebook/facebook.php';
require 'config/fbconfig.php';
require 'config/functions.php';
$facebook = new Facebook(array(
'appId' => APP_ID,
'secret' => APP_SECRET,
));
$user = $facebook->getUser();
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
if (!empty($user_profile )) {
# User info ok? Let's print it (Here we will be adding the login and registering routines)
$username = $user_profile['name'];
$uid = $user_profile['id'];
$email = $user_profile['email'];
$user = new User();
$userdata = $user->checkUser($uid, 'facebook', $username,$email,$twitter_otoken,$twitter_otoken_secret);
if(!empty($userdata)){
session_start();
$_SESSION['id'] = $userdata['id'];
$_SESSION['oauth_id'] = $uid;
$_SESSION['username'] = $userdata['username'];
$_SESSION['email'] = $email;
$_SESSION['oauth_provider'] = $userdata['oauth_provider'];
header("Location: home.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
$login_url = $facebook->getLoginUrl(array( 'scope' => 'email'));
header("Location: " . $login_url);
}
