title: how to crawl post posed in a closed group on facebook
body: <p>I want to crawl posts from a closed group I have joined. I read the facebook api but I still do not know how to solve this problem. I read this thread <a href="https://stackoverflow.com/questions/4112253/facebook-api-httpclient-wrapper-for-crawling-through-the-wall-posts-group-po">Facebook API / httpclient wrapper for crawling through the wall posts &amp; group posts of any user?</a> . But it is old and no good answers are provided. </p>
