I am using the RestFB client to fetch all post_ids of a Facebook Page.
The query is
select post_id from stream where source_id=265813166783408
Where the id if of the page I’m querying. It can be found here
I initially tried executing this without an access token. This gives a 104: Requires valid signature error from Facebook.
I looked up this error and the solution that many gave on SO is to use an access token. However if I try with an accessToken (with permissions: manage_pages, publish_stream, read_stream, offline_access, read_insights) then Facebook gives a different error 190: Impersonated access tokens can only be used with the Graph API.
Does this mean I shouldn’t use FQL for getting page posts. The Facebook documentation doesn’t mention anything on these lines but like I said it keeps alternating between these two errors.
PS: I can use the Graph API with my access token to fetch Posts but for my specific scenario I felt FQL would be a far better option, since I can nest this query into a query on the comments table (eventual aim).
Thank you.
UPDATE:
Please see Facebook developers for a discussion on this particular issue If you are using the RestFB library then also see the relevant issue
We encountered the same problem and found it to be an issue with using fbclient library and a page access token. We switched to calling the API directly (with the Apache HttpClient) and our FQL ran fine with the page access tokens.
