的index.php

<?php 
session_start(); 
include_once "facebook/fbaccess.php"; 
?>

fbaccess.php

<?php 
//Application Configurations 
$app_id  = "xxxxxxxxxxxxx"; 
$app_secret = "XXXXXXXXXXXXXXXXXXXXX"; 
$site_url = "http://xxxxxxxxx"; 

try{ 
include_once "facebook.php"; 
}catch(Exception $e){ 
error_log($e); 
} 
// Create our application instance 
$facebook = new Facebook(array(
'appId'  => $app_id, 
'secret' => $app_secret, 
'cookie' => true 
)); 

// Get User ID 
$user = $facebook->getUser(); 
// We may or may not have this data based 
// on whether the user is logged in. 
// If we have a $user id here, it means we know 
// the user is logged into 
// Facebook, but we don’t know if the access token is valid. An access 
// token is invalid if the user logged out of Facebook. 

$facebook->setExtendedAccessToken(); 
$access_token = $facebook->getAccessToken(); 

if($user){ 
//==================== Single query method ====================================== 
try{ 
    // Proceed knowing you have a logged in user who's authenticated. 
    $user_profile = $facebook->api('/me'); 
    $_SESSION['fid'] = $user_profile['id']; 
}catch(FacebookApiException $e){ 
    error_log($e); 
    $user = NULL; 
} 
//==================== Single query method ends ================================= 
} 

if($user){ 
// Get logout URL 
$logoutUrl = $facebook->getLogoutUrl(); 
}else{ 
// Get login URL 
$loginUrl = $facebook->getLoginUrl(array(
    'scope'   => 'publish_stream', 'offline_access', 
    'redirect_uri' => $site_url, 
    )); 
} 

?>

的index.php

<div id="mainMenu"> 
<?php if ($user) {echo '<a href="' . $logoutUrl . '"><h5>Logout</h5></a>'; }else{ echo '<a href="' . $loginUrl . '"><h5>Login</h5></a>';} ?> 
</div>

你不假设显示应用程序正确率 –

我认为问题将从您的会话结束，而不是从FACEBOOK。尝试增加您的服务器在您运行此应用程序的会话时间 – Vijay

不认为它是会话，但我不确定它是什么。正如我之前所说，我只是需要刷新它的工作，所以我猜测第二次刷新，它认识到我在Facebook上进入并重新授权。 – user1593846
