获取用户在Facebook中参加的活动的数量

I would like to get the event count that I have attended in the last 6 months. I am using graph api /user_id/events but am not getting any results.

You can play around with debugger at https://developers.facebook.com/tools/explorer.

Ensure you granted user_events permission scope:

FQL query:

SELECT eid FROM event_member WHERE uid = me() AND rsvp_status='attending'

Example:

As you can see, only one event id is attending.

For your case, it's more complicated because you have to compare the start_time in the range of last 6 months, and do pagination by start_time(get from last item of this page) accordingly. You can set a low LIMIT number to test. Put ORDER BY start_time DESC to make sure its pagination is based on start_time, not uid or something else.
