real-time update page feed

here I am for real update "page", add fields to status to receive the "status" of pages, I try to add as "link" fields to receive the subscription works but I do not receive notification when I publish a link, it's really difficult to have correct information

{ "object": "user", "callback_url": "http://*/fbcallback.php", "fields": [ 开发者_开发问答 "feed", "link", "status" ], "active": true }

As per the documentation at https://developers.facebook.com/docs/reference/api/realtime/ :

To setup a subscription, send a POST with the following parameters

It seems like you're posting a JSON object while you should do is a normal post with these variables (as if you're doing a with action="post").

Note, by the way, that the fields parameter needs to have a CSV value, so that would be "feed,link,status", and that there's no 'active' attribute.
