graph.facebook.com 用于 Facebook 页面

Question

我目前在一家互联网公司实习，他们希望我创建一个“品牌检查器”，以便访问者可以检查他们的品牌名称是否被 Facebook、Twitter、LinkedIn 等热门网站占用。

我发现通过访问 http://graph.facebook.com/，您可以查看 Facebook 上是否存在某个人/帐户。我目前正在尝试找到一种方法来检查 Facebook 上是否存在页面。我不需要帖子之类的细节，我只需要找出它是否存在。

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），但它根本不起作用。

<?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（顺便说一下

url_get_contents()

也是如此）。

curl

部分仅返回一个空白页。

TL;DR： 有没有一种（最好是简单的）方法可以让我检查 Facebook 页面是否存在？如果你们碰巧知道的话，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/所示检查该URL是否有

object_id

。例如，URL 也可以是 Facebook 页面链接

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

未采用的 URL（-> Facebook 页面）的响应是

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

与所拍摄的 Facebook 页面相反：

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