PHP使用Facebook登录创建无限重定向循环

我遇到Facebook登录和PHP问题。PHP使用Facebook登录创建无限重定向循环

下面的文件似乎是造成这个问题。一切正常，直到我与Facebook成功登录，并重新导向到这个文件时，浏览器最终必然引发无限重定向错误的位置。最后的else语句总是被执行导致循环...

任何想法？在此先感谢！

<?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); 
} 
?>

尝试注释'header（“Location：home.php”）;'和'header（“Location：”）。 $ login_url）;'，然后看看你是否仍然卡住...... – 2013-03-06 03:43:34

当你在页面顶部放置'session_start（）;'时会发生什么？每[登录服务器端应用程序（http://developers.facebook.com/docs/howtos/login/server-side-login/）会议是必需的。然后你从请求中获得一个'$ _GET ['code']'状态。 – Jon 2013-03-06 03:52:14

我有同样的问题，在base_facebook.php

寻找：

public static $CURL_OPTS = array(
    CURLOPT_CONNECTTIMEOUT => 10, 
    CURLOPT_RETURNTRANSFER => true, 
    CURLOPT_TIMEOUT  => 60, 
    CURLOPT_USERAGENT  => 'facebook-php-3.2' 
);

，并添加以下两行

CURLOPT_SSL_VERIFYPEER => false, 
CURLOPT_SSL_VERIFYHOST => false

所以你必须

public static $CURL_OPTS = array(
    CURLOPT_CONNECTTIMEOUT => 10, 
    CURLOPT_RETURNTRANSFER => true, 
    CURLOPT_TIMEOUT  => 60, 
    CURLOPT_USERAGENT  => 'facebook-php-3.2', 
    CURLOPT_SSL_VERIFYPEER => false, 
    CURLOPT_SSL_VERIFYHOST => false 
);
