我制作了一个应用程序，可以帮助用户从网站直接将照片发布到 fb 页面。

我现在面临的问题是，如果访问令牌过期，我每次都必须放置新的访问令牌。我需要一种自动获取用户访问令牌的方法。有什么办法吗？这是代码

    <?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
require_once 'library/facebook.php';
$facebook = new Facebook(array(
    'appId'  => 'My_app_ID',
    'secret' => 'My_App_secret',
    'fileUpload' => true
));


#It can be found at https://developers.facebook.com/tools/access_token/
#Change to your token.
$access_token = 'CAAHkfWZB9T84BACm0LqdF1V5BFcppXZCHM7mrRxy9g8SRvw6Wz2RFZBMnYsdgsg413fIE5mpZChgYvz0DiJGGDUsVn8CKkZAFWvm6GHvcGw2xeD8EKH0D7MdkWrdNvD08oXabjzyfPsSTZCxfj1qPg40z4rFUQs8zSOIZD';

$params = array('access_token' => $access_token);

#The id of the fanpage
$fanpage = '232241216922182';

#The id of the album
$album_id ='281594988653471';

//here Wa33D94 is the id of the admin of the page where the photos will be uploaded
$accounts = $facebook->api('/Wa33D94/accounts', 'GET', $params);

foreach($accounts['data'] as $account) {
    if( $account['id'] == $fanpage || $account['name'] == $fanpage ){
        $fanpage_token = $account['access_token'];
    }
}


$valid_files = array('image/jpeg', 'image/png', 'image/gif');

if(isset($_FILES) && !empty($_FILES)){
    if( !in_array($_FILES['pic']['type'], $valid_files ) ){
        echo 'Only jpg, png and gif image types are supported!';
    }else{
        $img = realpath($_FILES["pic"]["tmp_name"]);

        $args = array(
            'message' => 'This photo was uploaded via clixbox.net',
            'image' => '@' . $img,
            'aid' => $album_id,
            'no_story' => 1,
            'access_token' => $fanpage_token
        );

        $photo = $facebook->api($album_id . '/photos', 'post', $args);
        if( is_array( $photo ) && !empty( $photo['id'] ) ){
            echo '<p><a target="_blank" href="http://www.facebook.com/photo.php?fbid='.$photo['id'].'">Click here to watch this photo on Facebook.</a></p>';
        }
    }
}
