Retrieve Facebook Post Comments Using Graph API

Question

I tried to get Facebook comments using:

http://graph.facebook.com/[post_id]/comments 

It results only 2 of 15 comments, and without count info.

{     "data": [         {             "id": "[post_id]",             "from": {                 "name": "[name]",                 "id": "[id]"              },              "message": "[message]",              "created_time": "2011-01-23T02:36:23+0000"         },         {              "id": "[id]",              "from": {              "name": "[name]",                  "id": "[id]"              },             "message": "[message]",             "created_time": "2011-01-23T05:16:56+0000"         }     ] } 

Anyone know why only 2 comments?

Also, I want to retrieve comments (default number) or retrieve comments with my limit number, and get its comments count. Any idea? (Please use Graph API).

Answer 1

You need to call it from a secure request https and provide an access_token:

https://graph.facebook.com/19292868552_118464504835613/comments?access_token=XXX 

EDIT:
Added the object from the post document. try clicking the comments connection and then remove the access_token and try and see the difference.

Answer 2

In order to get the Like count and the comment count then you need to use a combination of the PostOwnerID and PostID not just the PostID

So for your example it would be:

https://graph.facebook.com/153125724720582_184234384932460/comments

Again, as mentioned in some of the other answers you need to use the https method along with an auth_token
