You can debug a graph object using Facebook graph API with <code>PHP-cURL</code>, by doing a <code>POST</code> to 

<pre><code>https://graph.facebook.com/v1.0/?id={Object_URL}&amp;scrape=1
</code></pre>

to make thing easier, we can wrap our debugger within a function:

<pre><code>function facebookDebugger($url) {

 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/v1.0/?id='. urlencode($url). '&amp;scrape=1');
 curl_setopt($ch, CURLOPT_POST, 1);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
 $r = curl_exec($ch);
 return $r;

}
</code></pre>

though this will update &amp; clear Facebook cache for the passed <code>URL</code>, it's a bit hard to print out each key &amp; its content and avoid errors in the same time, however I recommended using <code>var_dump()</code> or <code>print_r()</code> OR <a href="https://github.com/digitalnature/php-ref" rel="noreferrer">PHP-ref</a>

usage with <code>PHP-ref</code>

<pre><code>r( facebookDebugger('http://retrogramexplore.tumblr.com/') );
</code></pre>

Facts: I run a simple website that contains articles, articles dynamically acquired by scraping third-party websites/blogs etc (new articles arrive to my website every half an hour or so), articles which I wish to post on my facebook page. Each article typically includes an image, a title and some text.

Problem: Most (almost all) of the articles that I post on Facebook are not posted correctly - their images are missing.

Inefficient Solution: Using Facebook's debugger <a href="https://developers.facebook.com/tools/debug/" rel="nofollow">(this one)</a> I submit an article's URL to it (URL from my website, not the original source's URL) and Facebook then scans/scrapes the URL and correctly extracts the needed information (image, title, text etc). After this action, the article can be posted on Facebook correctly - no missing images or anything.

Goal: What I am after is a way to create a process which will submit a URL to Facebook's debugger, thus forcing Facebook to scan/scrape the URL so that it can then be posted correctly. I believe that what I need to do is to create an HTML POST request containing the URL and submit it to Facebook's debugger. Is this the correct way to go? And if yes, as I have no previous experience with CURL, what is the correct way to do it using CURL in PHP?

Side Notes: As a side note, I should mention that I am using short URLs for my articles, although I do not think that this is the cause of the problem because the problem persists even when I use the canonical URLs. 

Also, the Open Graph meta tags are correctly set (og:image, og:description, etc).

Facts：我运行一个简单的网站，其中包含文章、通过抓取第三方网站/博客等动态获取的文章(新文章每半个小时左右到达我的网站)，我希望在facebook页面上发布这些文章。每一篇文章通常包括一个图像，一个标题和一些文本。Problem：我在Facebook上发布的大部分(几乎所有)文章都没有正确发布--它们的图片不见了。低效解决方案：使用Facebook的调试器向其提交一篇文章的URL (来自我的网
