How to use Python to login to a webpage and retrieve cookies for later usage?


Tag : python , By : bashmish

fixed the issue. Will look into that further I want to download and parse webpage using python, but to access it I need a couple of cookies set. Therefore I need to login over https to the webpage first. The login moment involves sending two POST params (username, password) to /login.php. During the login request I want to retrieve the cookies from the response header and store them so I can use them in the request to download the webpage /data.php.
import urllib, urllib2, cookielib

username = 'myuser'
password = 'mypassword'

cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
login_data = urllib.urlencode({'username' : username, 'j_password' : password})
opener.open('http://www.example.com/login.php', login_data)
resp = opener.open('http://www.example.com/hiddenpage.php')
print resp.read()

WGET, Cookies and 302 Redirect

With these it helps I used to always have trouble with wget and cookies (trying to make wget use my Mozilla cookies, etc...) so I switched to using the Perl library WWW::Mechanize. It handles cookies for you as well as all of the usual things you'd expect out of a browser, like 302 handling and history.
An simple example that logs into a site, grabs all JPGs and clicks a "Next" link for pagination:
use warnings;
use strict;
use WWW::Mechanize;
use File::Slurp;

my $mech = WWW::Mechanize->new;
$mech->get('http://example.com/login') || die;
$mech->submit_form( form_name => 'login_form',
                    fields => { username => 'me',
                                password => 'secret' } ) || die;

while (1) {
   for my $link ($mech->links) {
      my $url = $link->url;
      if ($url =~ /(image_\d+\.jpg)\z/) {
         my $file = $1;
         $mech->get($url);
         File::Slurp::write_file($file, $mech->content);
         $mech->back; # like the browser back button                                
      }
   }
   # look at next page, if any                                                      
   my $result = $mech->follow_link(text_regex => qr/Next/);
   if (!$result) {
      last;
   }
}

Using Python to login webpage (cookies GET and POST involved)

I wish did fix the issue. I am trying to use Python 2.7.6 to login a website. the login logic contains 2 steps in 2 webpages. , How about just going with one of the two?
import mechanize;

browser = mechanize.Browser()
browser.addheaders = [('...')]

browser.open(YOUR_URL)
browser.select_form(FORM_NAME)
browser.form['USERNAME_FIELD'] = 'abc'
browser.form['PASSWORD_FIELD'] = 'password'
browser.submit()
print browser.response().read()
print browser.geturl()

wget cookies login script: same site, HTTP script works, HTTPS doesn't

This might help you I looked at what my browser was doing different then added --header="Referer: ${LOGIN_URL}" to the second wget call and it worked.
Not entirely sure 1. Why Django would be rejecting something without a Referer. I guess it makes sense(?) 2. Why it was working on the HTTP only site. But ... moving on.

Redirect users to the login if they are not authenticated and to the homepage if authenticated when accessing a url that

    return $this->hasMany(Conference::class, 'conference_creator_id');
}
