I need to write a Python script to do the following:

- Connect to a URL and accept any certificate - self-signed or authoritative
- Provide login name/password credentials
- Fill in some presented fields
- Hit a "Submit" button

Why? Because I don't want to have to start a browser and do this
interactively every time I authenticate with a particular server.
I want to do this at the command line with no interactive intervention.

I know Python pretty well. I don't quite know how to do this and
was hoping someone had a simple pattern they could share for
doing this.

TIA,

The mechanize module (http://wwwsearch.sourceforge.net/mechanize/) might be a place to start. I've done something similar with code like this:

response = mechanize.urlopen(login_form_url)
forms = mechanize.ParseResponse(response, backwards_compat=False)
response.close()
form = forms[0] # might be more than one, though
# fill the form
form.set_value(username, name='userName')
form.set_value(password, name='password')
# set headers - user-agent, etc.
login_request = form.click()
login_response = mechanize.urlopen(login_request)
login_response_content = login_response.read()
....

Does it handle self-signed SSL certs?

No idea. you'd have to try it.

Hello Tim,

I think you may also want to take a look at python requests.
http://docs.python-requests.org/en/l...user/advanced/

From my experience they do a much nicer job than urllib and anything I've tried.
You will probably get what you want out of them easily and in no time.
