[Tutor] Firstrade Authentication: Form Management

[Federo]

Kent hi

I do hope we are now close to the final solution. I have used Firefox plagin 
TamperData as you suggested and concequently amanded the code. Header Fields 
are know clear (you can see them in the attached file). There is some problem 
with Python code:

import urllib2
import urllib
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor())
urllib2.install_opener(opener)
f = opener.open('https://investor.firstrade.com/firstrade/login.do')
data = f.read()
f.close()
params = dict(username='janezfedero', password='kmet555', destination='')
params['login.x'] = 'Log+In'
params = urllib.urlencode(params)
f = opener.open('https://investor.firstrade.com/firstrade/login.do', params)
data = f.read()
f.close()
#print(data)

#params2 = dict(contentProvider='pinnacor', quoteSymbol='goog', 
optionChain='goog', countryCode='US', optionRange='NTM', tickerSymbol='goog', 
ContentType='stockQuote')
params2['contentProvider'] = 'pinnacor'
params2['quoteSymbol'] = 'goog'
params2['optionChain'] = 'goog'
params2['countryCode'] = 'US'
params2['optionRange'] = 'NTM'
params2['tickerSymbol'] = 'goog'
params2['contentType'] = 'stockQuote'
params2['quote.x'] = 'submitted'
f = opener.open('https://investor.firstrade.com/firstrade/mainmenu.do', params2)
data2 = f.read()
f.close()
print(data2)

Error Message:
File "C:\Python25\lib\urllib2.py", line 381, in open
    response = self._open(req, data)
  File "C:\Python25\lib\urllib2.py", line 399, in _open
    '_open', req)
  File "C:\Python25\lib\urllib2.py", line 360, in _call_chain

    return self.do_open(httplib.HTTPSConnection, req)
  File "C:\Python25\lib\urllib2.py", line 1079, in do_open
    h.request(req.get_method(), req.get_selector(), req.data, headers)

    return self._ssl.write(stuff)
TypeError: write() argument 1 must be string or read-only buffer, not dict

Cheers, Fedo
