Facebook Graph API吸引用户喜欢

Question

我试图吸引用户的Facebook喜欢。如果我单独为每个用户拨打电话，那么呼叫成功，但如果我遍历我的数据库中的用户，则呼叫立即失败。脚本如下。不知道为什么会这样。什么是解决方案？

<?php

$conn = mysql_connect('***', '***', '*****');
mysql_select_db('*****', $conn);

//Application Configurations
$site_url = $webPath . 'index.php';

try {
    require_once $behindPath . "src/facebook.php";
} catch (Exception $e) {
    error_log($e);
}


// Create our application instance
$facebook = new Facebook(array(
    'appId' => $app_id,
    'secret' => $app_secret,
        ));

//$usertoken = $facebook->setAccessToken($access_token);
// Get User ID
try {
    $user = $facebook->getUser();
} catch (Exception $e) {
    header("Location: error.php?err= Some Error has occured. Please try again Later.");
    die();
}


//if($user){
//$accessToken  = $facebook->getAccessToken(); 

//以下是获取喜欢尚未被提取的用户的facebook ID的查询

$query = "SELECT uid, facebook_access_token FROM fbusers WHERE facebook_id IN(SELECT facebook_id FROM user_self WHERE device = 'ios' AND facebook_id NOT IN(SELECT facebook_id FROM user_interest) ORDER BY id DESC)";
$res = mysql_query($query);
$numrows = mysql_num_rows($res);
while ($row = mysql_fetch_array($res)) {
    $access_token = $row['facebook_access_token'];
    $uid = $row['uid'];
    echo $uid . "<br />";

    try {

        // Proceed knowing you have a logged in user who's authenticated.
        $usertoken = $facebook->setAccessToken($access_token); //echo $usertoken; exit;
    } catch (FacebookApiException $e) {
        error_log($e);
    }
