Codeignitor，Facebook javascript SDK，PHP SDK重定向在Facebook登录后不会getUser（）直到刷新 [英] Codeignitor, Facebook javascript SDK, PHP SDK Redirect after facebook login doesnt getUser() until refresh
问题描述
过程如下。
1. User clicks Facebook Login button
2. User signs in and grants perms
3. Facebook redirects uses FB.Event.subscribe auth.login to redirect my login controller
4. My login controller loads the fbconnect module and chains the method Connect()
5. Connect() Checks if there is a facebook user using getUser() and if true checks if they are an existing user to log them in or returns false if no facebook user was found.
一切正常，除了唯一的问题是重定向到登录页面后连接返回False，当它应该事实上，正确的是，fbuser已经登录并已经授予了perms。如果我刷新，但一切正常，用户登录，如果存在或新的发送到注册页面。以下是我的代码..
Everything works except the only problem is after being redirected to the login page Connect returns False when it should in fact be true sine the fbuser is logged in and has granted perms. If I refresh however everything works, the user is logged in if exists or if new is sent to the signup page. Below is my code..
<div id="fb-root"></div>
<script>
//initializing API
window.fbAsyncInit = function() {
FB.init({appId: '(My app id)', status: true, cookie: true,
xfbml: true, // channel.html file
oauth : true
});
FB.Event.subscribe('auth.login', function(response) {
window.location='http://www.(Mysite).com/login';
});
FB.Event.subscribe('auth.logout', function(response) {
window.location='http://www.(Mysite).com/logout';
});
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>
Fbconnect.php
Fbconnect.php
class Fbconnect extends MX_Controller {
public $fb_user = null;
public $fb_user_id = null;
// Initilize Fabebook
public function __construct()
{
parent::__construct();
$this->config->load("facebook");
require 'facebook.php';
$this->facebook = new Facebook(array(
'appId' => $this->config->item('appId'),
'secret' => $this->config->item('Secret')
));
// Get user from FB
$this->fb_user_id = $this->facebook->getUser();
if ($this->fb_user_id):
try {
// Proceed knowing you have a logged in user who's authenticated.
$this->fb_user = (object)$this->facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$this->fb_user = null;
}
endif;
}
public function connect(){
// Check for FB object
if($this->fb_user):
// FB Object found
// Check if user exists
$this->load->model('facebook/m_facebook');
$user = $this->m_facebook->getUser($this->fb_user->id);
// If we find a user and fb connect is true
if($user):
// user found log them in
if($this->ion_auth->login($user->username, $user->password, true, true)):
redirect('', 'refresh');
endif;
else:
// There is a fb object & the user is not logged in & doesnt exist in db yet must be new
redirect('signup/facebook', 'refresh');
endif;
else:
// No FB user or user not logged in
return false;
endif;
}
验证/登录代码（仅涉及到Facebook的部分）
The auth/login code ( just the part that involves facebook)
$this->load->module('facebook/fbconnect')->connect();

推荐答案
我似乎已经弄清楚了。我对javascript进行了更改：
Well I seem to have figured this out. I made this change to the javascript:
FB.Event.subscribe('auth.login', function(response) {
FB.api('/me', function(response) {
window.location.reload();
});
});
我想通过添加FB.api（'/ me'，function（response）{} ）;它以某种方式使getUser（）返回true。如果有其他人有getUser（）返回0尝试这个。无论如何，我希望这有助于别人：）
I guess that by adding the FB.api('/me', function(response){}); it somehow made the getUser() return true. If anyone else is having getUser() return 0 try this. Anyway I hope this helps others :)
