用于Facebook Pages的graph.facebook.com

Question

我目前正在一家互联网公司实习，他们想让我创建一个“品牌检查器”，以便访问者可以检查他们的品牌名称是否出现在Facebook，Twitter，LinkedIn等热门网站上。

我发现通过访问http://graph.facebook.com/可以查看Facebook上是否存在个人/帐户。 我目前正在尝试寻找一种方法来检查Facebook上是否存在某个页面。 我不需要发布之类的详细信息，只需要查找是否存在。

到目前为止，我已经尝试了下面的代码（注释的代码和未注释的代码），但根本不起作用。

<?php
/*$z = file_get_contents("http://www.facebook.com/search/results/?q=example");
preg_match("#LifeStamp#s", $z, $matches);
echo $matches[1];
if($matches == 1){
    echo "In there!";
    } elseif($matches == 0) {
    echo "No";
    } elseif($matches == "false") {
    echo "Nope";
    } else {
    echo "Nopenopenope";
    };*/
$ch = curl_init(); 
$timeout = 0; 
curl_setopt ($ch, CURLOPT_URL, 'http://www.facebook.com/search/results/?q=example'); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); 
$file_contents = curl_exec($ch); 
curl_close($ch); 

var_dump($file_contents);
echo $file_contents[1];
?>

file_get_contents()给出错误（ url_get_contents()也url_get_contents() ）。 curl -part仅返回空白页。

TL; DR：我可以通过一种（最好是简便的）方式检查Facebook页面是否存在吗？ 而且，如果您碰巧知道的话，Twitter和LinkedIn也是如此。

提前致谢！

您可以使用端点

https://graph.facebook.com/?id={url}

如https://developers.facebook.com/docs/graph-api/reference/v2.2/url/中所示，以检查该URL是否存在object_id 。 URL也可以是Facebook页面链接，例如

https://graph.facebook.com/?id=https://www.facebook.com/fgshdioghsdlfghsldfgkl

未采用的URL（-> Facebook Pages）的响应为

{
   "id": "https://www.facebook.com/fgshdioghsdlfghsldfgkl"
}

与以下Facebook页面相反：

https://graph.facebook.com/?id=https://www.facebook.com/cocacola
