How to log in to a website using installed twill?

Question

Hello, everybody!!!!

I have just successfully installed TWILL on my computer with the help of one very supportive member of "StackOverflow" (you can check it out HERE) and have tried to run one of the simple examples on the twill documentation page (you can see that page HERE). Here is that example:

Let's say my username on www.slash.org is lynxye and my password is mammal. When I try to enter that example code into my Python prompt, I can only type and enter the first line of the code because when I click on "Enter" to start a new line, I get some error messages right away:

The same happens when I try to enter this code into my terminal:

I think I miss out on some basics here. Perhaps, I need to create a file that would contain that code and then run that file somehow, but I really don't know where I need to create that file and with what extensdion.

Can anyone, please, help me with this?

Answer 1

The angle brackets aren't meant to be entered literally; they're just there to indicate you should enter a value. Try

setlocal username lynxye

instead.

Answer 2

You need to run those commands inside twill shell, instead of python shell

D:\tmp\twill-0.9>python twill-sh

 -= Welcome to twill! =-

You can put twill commands when you see >>

or there is 2 only lines in twill-sh file

import twill.shell
twill.shell.main()

you can just copy paste that 2 lines to python prompt.

>>> import twill.shell
>>> twill.shell.main()

 -= Welcome to twill! =-

This'll do it:

>>> import twill.commands
>>> import re
>>> 
>>> class browser:
...    def __init__(self, url="http://www.slashdot.org"):
...       self.a=twill.commands
...       self.a.config("readonly_controls_writeable", 1)
...       self.b = self.a.get_browser()
...       self.b.set_agent_string("Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.8.1.14) Gecko/20080404 Firefox/2.0.0.14")
...       self.b.clear_cookies()
...       self.url=url
...    def slashdot(self, loginName, passwd):
...       self.b.go(self.url)
...       f = self.b.get_form("1")
...       regexp = re.compile("Log In")
...       link = self.b.find_link(regexp)
...       if link:
...          self.b.follow_link(link)
...          f=self.b.get_form("2")
...          f["unickname"] = loginName
...          f["upasswd"] = passwd 
...          self.a.fv("2", "userlogin", "") 
... 
>>> 
>>> t=browser()
>>> t.slashdot("username", "password")
==> at http://slashdot.org/
==> at http://slashdot.org/my/login
forcing read-only form field to writeable

Its also easier if you use BeautifulSoup to parse the html
