I received this error when I run your code

Traceback (most recent call last):
File "facebook-craw.py", line 158, in
main()
File "facebook-craw.py", line 16, in main
pull(user, passw)
File "facebook-craw.py", line 49, in pull
pfi = mxt.group(1)
AttributeError: 'NoneType' object has no attribute 'group'

I don't know what is problem

It appears FB no longer uses the post_form_id field. I'm not sure whether there's an equivalent field or not. Use a traffic monitor to view the POST data, and modify it as needed.

Thanks for reply, I am new in python and web crawler, what do you mean by saying " use traffic monitor to view the POST data, and modify it as needed"

This might be a good place to start: http://stackoverflow.com/questions/5827267/sniff-post-variables-through-https

I made this change after remove post_form_id field

mxt = re.search('name="m_ts" value="(\w+)"', res.read())
pfi = mxt.group(1)
print 'Using PFI: %s' % pfi
res.close()

I managed to logging, the script managed to craw some user profile but at after several minutes I received the following error

thanks

I get a login failure with this script. I've even had it print out user and passw while assembling data and it looks like the correct info is there.
