How to retrieve FB comments/shares for a specific URL - facebook

Question

I would like to retrieve the text,author of comments or shares made for a specific url.
I have for instance the following target : http://www.graphemeride.com/blog/comment-j-ai-triche-aux-golden-blog-awards
I can retrieve the number of comments and shares with FQL :
SELECT
url, share_count , comment_count, comments_fbid
FROM
link_stat
WHERE
url="http://www.graphemeride.com/blog/comment-j-ai-triche-aux-golden-blog-awards"
I get the following result :
{
"data": [
{
"url": "http://www.graphemeride.com/blog/comment-j-ai-triche-aux-golden-blog-awards",
"share_count": 27,
"comment_count": 26,
"comments_fbid": 357167807708699
}
]
}
My plan was to use the comment FQL query to retrieve the different comments.
SELECT
id, text
FROM
comment
WHERE
object_id="357167807708699"
However I get an empty result dataset.
I added the required access token, but kind of understood that I can only get comments I made about this object, not public comments or shares.
Is there an alternative way to get access to what people publicly said about an url ?

Answer 1

The comment count on the link_stat table is the for the number of comments on the SHARES of this link and not the number of comments on the comments plugin on that page itself.
Whereas the comments table returns you the number of comments from the comments plugins on that page.
As your page isn't using any fb comments plugin, you don't get any comments back.
