Auto-login in python using mechanize_问答_开发者

I have an almost working code to connect to a server and do a search. But there is some issue here with the code. This is what I do now with the following python script. I login to the site. Construct a url for the search result and access the search page and open it in a browser. But issue I am facing here is that I am getting a session expired page. But if I have a logged in page open(manually) in the browser, this constructed url is giving me the desired output. So my question here is that How can I keep the 'logged in' session in the script active and open the constructed url in a browser which yield me the desired output.

You need to share the session (or session identifier, which is probably stored in a cookie) between Mechanize and your browser. This is not easy, and definitely not portable between browsers (if you want that).

However, there appears to be support in Mechanize for the SQLite database format that Firefox uses since version 3: https://github.com/jjlee/mechanize/blob/master/mechanize/_firefox3cookiejar.py

You may want to check the documentation for that.

This might be helpful for the login part:

(Was able to get site to send data using wireshark. Also "user" might be something else e.g. "username" same with "password". Once again wireshark would help with this. Also could look at source of login page. Good luck!!!)

from urllib import urlencode

from urllib2 import Request, urlopen

req = Request('www.site.com',urlencode({'user':'userhere', 'password':'passwordhere'}))

open = urlopen(req)
