Facebook Graph API Comments

I'm trying to use facebooks graph api on my blog for users to leave comments and view comments for a article there viewing, ive looked at there graph api page and I'm always getting an error 'unauthorised post request'

I have request publish_stream and status_update when users accept my app via fbconnect, I'm using similar code as below to post a comment:

facebook -> api('/http://www.mysite.com/blog/article-title-here/likes', 
   'post', 
   array(
      'id' => 'http://www.mysite.com/blog/artic开发者_如何学Cle-title-here',
      'message' => 'users comment',
      'created_time' => PHP_DATE_FUNCTION
   )
);

You're going about this the wrong way...

You can only use the publish method to publish on a user's, page's, group's wall. You can't pass an id around like that:

As an alternative way, you might want to look into the comment box plugin that facebook offers:

facebook -> api('/'.$post_id.'/comments', 
   'post', 
   array(
      'message' => 'users comment',
   )
);

i think you you need to use latest facebook graph api if you are try to post comment on posts or photo then use this
