python and mechanize to login into university webpage

Question

I know quite a few people asked a similar question like this, but after looking though the answers and following this tips I can't get this script to work...

Here is my problem... I am trying to write a python script using the "mechanize" module to login into my university "meal balance" page and get the source html of the page that displays my declining balance for food, then I will parse the html source and get the numbers...

The problem is accessing the said webpage and logging in...

This is the login website: http://www.wcu.edu/11407.asp Towards the end you will see the FORM I need to fill...

Here is the code I am trying to use in order to login and get the page with my declining balance:

import mechanize, cookielib
from time import sleep

url   = 'http://www.wcu.edu/11407.asp'
myId  = 'xxxxxxxx'
myPin = 'xxxxxxxx'

# Browser
#br = mechanize.Browser()
#br = mechanize.Browser(factory=mechanize.DefaultFactory(i_want_broken_xhtml_support=True))
br = mechanize.Browser(factory=mechanize.RobustFactory()) # Use this because of bad html

# Cookie Jar
cj = cookielib.LWPCookieJar()
br.set_cookiejar(cj)

# Browser options
br.set_handle_equiv(True)
br.set_handle_gzip(True)
br.set_handle_redirect(True)
br.set_handle_referer(True)
br.set_handle_robots(False)

# Follows refresh 0 but not hangs on refresh > 0
br.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=1)


# User-Agent (fake agent to google-chrome linux x86_64)                         
br.addheaders = [('User-agent','Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11'),
                 ('Accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'),
                 ('Accept-Encoding', 'gzip,deflate,sdch'),                      
                 ('Accept-Language', 'en-US,en;q=0.8'),                         
                 ('Accept-Charset', 'ISO-8859-1,utf-8;q=0.7,*;q=0.3')] 

# The site we will navigate into, handling it's session
br.open(url)

for f in br.forms():
    print f


# Select the third (index two) form
br.select_form(nr=2)

# User credentials
br.form['id']  = myId
br.form['PIN'] = myPin

br.form.action = 'https://itapp.wcu.edu/BanAuthRedirector/Default.aspx

# Login
res = br.submit().read()

sleep(10)

f = file('mycatpage.html', 'w')
f.write(res)
f.close()

This gives me the login page back and not the page after.... Why???

Why don't you just check where the error originates from by typing your code into a python shell? Or testing it with another site? There are a number of obvious possibilities to test against the reason of the error you face.

the error originates on the submit, that is exactly the problem, it works fine on other websites... That is why I posted this, maybe someone can find something I missed.... – Perun Apr 06 '12 at 18:52
