Python and mechanize login script

Question

Hi fellow programmers!

I am trying to write a script to login into my universities \"food balance\" page using python and the mechanize module...

This is the pag

Answer 1

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

I believe this is the problem line.

Try changing it to

br['id'] = myId
br['PIN'] = myPin

I'm also pretty sure that you don't need br.form.action = 'https://itapp.wcu.edu/BanAuthRedirector/Default.aspx' because you have already selected the form so just calling submit should work, but I could be wrong.

Additionally, I have done a similar task just using urllib and urllib2, so if this doesn't work I will post that code.

Edit: here is the the technique that I used with urllib and urllib2:

import urllib2, urllib

opener = urllib2.build_opener(urllib2.HTTPCookieProcessor())
urllib2.install_opener(opener)
encoded = urllib.urlencode({"PIN":my_pin, "id":my_id})
f = opener.open('http://www.wcu.edu/11407.asp', encoded)
data = f.read()
f.close()

Edit 2:

>>> b = mechanize.Browser(factory=mechanize.RobustFactory())
>>> b.open('http://www.wcu.edu/11407.asp')
<response_seek_wrapper at 0x10acfa248 whose wrapped object = <closeable_response at 0x10aca32d8 whose fp = <socket._fileobject object at 0x10aaf45d0>>>
>>> b.select_form(nr=2)
>>> b.form
<mechanize._form.HTMLForm instance at 0x10ad0dbd8>
>>> b.form.attrs
{'action': 'https://itapp.wcu.edu/BanAuthRedirector/Default.aspx', 'method': 'post'}

This could be your problem? Not sure.

Edit 3:

Used an html inspector, I think there's a decent chance you need to set 'wcuirs_uir' to 'https://cf.wcu.edu/busafrs/catcard/idsearch.cfm'. I'm 95% sure that will work.

Answer 2

I suggest the following library: http://docs.python-requests.org/en/latest/

It is a nice and easy library. It has a good documentation. I have used this library to do different kind of scripting, just like the one you are doing.

You need to do something like this:

import requests 

s = requests.Session()
url = 'https://itapp.wcu.edu/BanAuthRedirector/Default.aspx'                    
myId = 'xxxxxxxx'                                                               
myPin = 'xxxxxxxx'  
headers = {'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'}
data = {'id':myId,                                                          
        'PIN':myPin,                                                        
        'submit':'Request Access',                                          
        'wcuirs_uri':'https://cf.wcu.edu/busafrs/catcard/idsearch.cfm'} 
response = s.post(url, headers = headers, data=date)

if response.status_code == 200: #Maybe add another constraint to be sure we are logged in
    #Now do any call you want
    response = s.get(another_url)
    print response.text

Another solution I've used in messing w/ ASPX is robobrowser.

For example:

def auth(mailbox, password):
    browser = RoboBrowser(history=False)
    browser.open(oc_auth_uri)

    signin = browser.get_form(id='aspnetForm')
    signin['SubLoginControl:mailbox'].value = mailbox
    signin['SubLoginControl:password'].value = password
    signin['SubLoginControl:javascriptTest'].value = 'true'
    signin['SubLoginControl:btnLogOn'].value = 'Logon'
    signin['SubLoginControl:webLanguage'].value = 'en-US'
    signin['SubLoginControl:initialLanguage'].value = 'en-US'
    signin['SubLoginControl:errorCallBackNumber'].value = 'Entered+telephone+number+contains+non-dialable+characters.'
    signin['SubLoginControl:cookieMailbox'].value = 'mailbox'
    signin['SubLoginControl:cookieCallbackNumber'].value = 'callbackNumber'
    signin['SubLoginControl:serverDomain'].value = ''

    browser.submit_form(signin)
    return browser

Note: You may need to update the form to add hidden form fields such as __VIEWSTATE and friends to the form prior to submitting. See this post for further info.
