I am having a problem getting the POST data from a Facebook action. When you submit a comment on FB it posts to this url: https://www.facebook.com/ufi/add/comment/?__pc=EXP1%3ADEFAULT In the request, the post data for the post exists: Here is an example of the actual comment from the post data:
comment_text:test this is a test
When I try to access this through a Chrome Extension I can't seem to get this data. I've tried parsing the requestBody, but it is empty. I then tried to see if any of the other requestmethods would work, and I can't seem to find the data anywhere.
