Facebook json url to retrieve event wall feed

I'm currently trying to pull the wall from this event page: https://www.facebook.com/event.php?eid=139373546157232, but I'm not sure how I go about getting the graph url to use in an ajax request.. I want to get it in json format and I also need the auth token.. This event is not private so should I need a auth token just to read the data?

I have used this url to get the event info: https://graph.face开发者_高级运维book.com/139373546157232 but the object has limited data...

Thank you

Events have a number of 'connections' to give you more data:

Unfortunately it seems you do need an access token to access the interesting parts of the info. However, a public access token from any user should be sufficient if the event is public. Perhaps generate an offline access token as yourself and store it permanently and try using that if you need to query event info in a non-connected-user context.
