Facebook PHP API 多个用户一台计算机强制注销

我正在开发一个基本上将在信息亭中运行的应用程序，重点是允许用户在企业时能够登录到Facebook，并在登录后发布一条消息说他们在那里，后记他们得到了一张优惠券。

问题出现了，在他们登录然后注销后，下一个使用其帐户登录的人最终会以上一个用户的身份发布，这继续令人作呕。

获得优惠券后，脚本会在 15 秒后自动将其注销，并将应用程序返回到主屏幕供下一个用户使用。当他们登录时，他们能够这样做，它会将他们返回到页面，要求发布权限，但它正在提取所有以前的用户信息。这是发送到Facebook登录后在页面中调用的代码。

<?php
//include the Facebook PHP SDK
include_once 'couponGenerator/facebook.php';
//start the session if necessary
if( session_id() ) {
} else {
session_start();
}
//instantiate the Facebook library with the APP ID and APP SECRET
 $facebook = new Facebook(array(
'appId' => '00000000000',
'secret' => '000000000000000000000',
'cookie' => true,
'status' => true,
'oath' => true
));
$access_token = $facebook->getAccessToken();
$_SESSION['active'][$access_token];
//get the news feed of the active page using the page's access token
$page_feed = $facebook->api(
'/me/feed',
'GET',
array(
    'access_token' => $_SESSION['active']['access_token']
)
);
$fbuser = $facebook->api('/me');
//var_dump($page_feed); exit;
?>

尝试在主页上删除facebook cookie和会话，但这并没有解决任何问题，我只是想弄清楚我做错了什么，任何建议都非常受欢迎。

$facebook->destroySession();
$facebook->_killFacebookCookies();
 public function _killFacebookCookies() 
{ 
    // get your api key 
    $apiKey = $this->getAppId();
    // get name of the cookie 
    $cookie = $this->getSignedRequestCookieName();
    $cookies = array('user', 'session_key', 'expires', 'ss'); 
    foreach ($cookies as $name)  
    { 
        setcookie($apiKey . '_' . $name, false, time() - 3600); 
        unset($_COOKIE[$apiKey . '_' . $name]); 
    } 
    setcookie($apiKey, false, time() - 3600); 
    unset($_COOKIE[$apiKey]);
    $this->clearAllPersistentData();
    }

这是更新的连接类`

<?php
//include the Facebook PHP SDK
include_once 'facebook.php';
//instantiate the Facebook library with the APP ID and APP SECRET
$facebook = new Facebook(array(
    'appId' => '122628977190080',
    'secret' => '123123123123123123123123',
    'cookie' => true
));
    $access_token = $facebook->getAccessToken();
    unset ($_SESSION['active'][$access_token]); 
    session_unregister ($_SESSION['active'][$access_token]); 
//Get the FB UID of the currently logged in user
$user = $facebook->getUser();
//if the user has already allowed the application, you'll be able to get his/her FB UID
if($user) {
    //start the session if needed
    if( session_id() ) {
    } else {
        session_start();
    }
    //do stuff when already logged in
    //get the user's access token
    $access_token = $facebook->getAccessToken();
    //check permissions list
    $permissions_list = $facebook->api(
        '/me/permissions',
        'GET',
        array(
            'access_token' => $access_token
        )
    );
    //check if the permissions we need have been allowed by the user
    //if not then redirect them again to facebook's permissions page
    $permissions_needed = array('publish_stream', 'email');
    foreach($permissions_needed as $perm) {
        if( !isset($permissions_list['data'][0][$perm]) || $permissions_list['data'][0][$perm] != 1 ) {
            $login_url_params = array(
                'scope' => 'publish_stream,email',
                'fbconnect' =>  1,
                'display'   =>  "page",
                'next' => 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']
            );
            $login_url = $facebook->getLoginUrl($login_url_params);
            header("Location: {$login_url}");
            exit();
        }
    }
    //if the user has allowed all the permissions we need,
    //get the information about the pages that he or she managers
    $accounts = $facebook->api(
        '/me/accounts',
        'GET',
        array(
            'access_token' => $access_token
        )
    );
    //save the information inside the session
    $_SESSION['access_token'] = $access_token;
    $_SESSION['accounts'] = $accounts['data'];
    //save the first page as the default active page
    $_SESSION['active'] = $accounts['data'][0];
    //redirect to manage.php
    header('Location: ../facebook_result.php');
} else {
    //if not, let's redirect to the ALLOW page so we can get access
    //Create a login URL using the Facebook library's getLoginUrl() method
    $login_url_params = array(
        'scope' => 'read_stream,email',
        'fbconnect' =>  1,
        'display'   =>  "page",
        'next' => 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']
    );
    $login_url = $facebook->getLoginUrl($login_url_params);
    //redirect to the login URL on facebook
    header("Location: {$login_url}");
    exit();
}

？>'

调用注销脚本后，我在主页上运行这段代码以查看是否设置了所有内容。

<?php
        try {
    $uid = $facebook->getUser();
    $fbme = $facebook->api('/me');
    echo "$uid";
} catch (FacebookApiException $e) { 
    print_r($e);
}
        ?>

它给了我这个结果
