Facebook api php - 检查用户是否喜欢该页面

Question

尝试用php检查用户是否喜欢facebook。检查过类似的问题，他们似乎已经过时了。该应用程序具有user_likes的权限。使用javascript进行登录。在php / js中尝试两种解决方案都返回空结果。

$fb = new Facebook\Facebook([
    'app_id' => '000',
    'app_secret' => '000',
    'default_graph_version' => 'v2.4',
]);

$helper = $fb->getJavaScriptHelper();

try {
    $accessToken = $helper->getAccessToken();
} catch(Facebook\Exceptions\FacebookResponseException $e) {
    echo 'Graph returned an error: ' . $e->getMessage();
    exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
    echo 'Facebook SDK returned an error: ' . $e->getMessage();
    exit;
}

$response = $fb->get('/me/likes/40796308305', $accessToken);

if ( $_GET['debug']=='1' ) {    
    echo("<pre>");
    print_r($response);
    echo("</pre>");
}

我得到的回答如下：
