因此，正如标题所暗示的那样，我正在使用 Facebook php sdk 在我的网站上授权用户，我遇到的问题是，在登录几分钟后，我刷新页面 $user = $facebook->getUser() ; 消失了，页面认为我已注销，但如果我再次刷新，它会再次被授权。

索引.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,
    ));
}

?>

索引.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>

检查您的会话生命周期设置和 cookie。当您持续浏览您的网站或仅在一段时间不活动后是否存在相同的行为？
