How to build FaceBook "Like Button" that likes a Page message?

For example:

• I have a FaceBook Page about my website.

• On my website, I display my 3 most recent FaceBook page messages (graph.facebook开发者_运维问答.com/[pageId]/[more parameters])

• Next to each FaceBook Page message (as they appear on my website) I would like to add a FaceBook Like button. When the like button is clicked, a "Like" should be given to the FaceBook Page Message. How can this be done?

Simply use the permalink of the post as your url in an fb:like button. The tricky part will be figuring out what the permalink is, since it takes different forms if it's a link, status, or video. For a link or status update, it's this format:

http://www.facebook.com/<PAGE_USERNAME>/posts/<POST_ID> 

Or, if you don't have a username:

http://www.facebook.com/permalink.php?story_fbid=<POST_ID>&id=<PAGE_ID>

You can determine the post ID and page ID by accessing http://graph.facebook.com/<PAGE_ID>/posts and splitting the id string on the _.

You should be able to POST to the /likes URL of any object that supports likes. No arguments should be specified. You can remove a like by executing a DELETE request to the same URL.

/OBJECT_ID/likes
Like the given object (if it has a /likes connection)

So the URL you should POST to, is https://graph.facebook.com/[pageId]/likes
