Use cookielib in Python to simulate website login, pythoncookielib

The Python login Simulated Program is briefly mentioned above, but it is not clearly written. Here we will add a Python login simulated sample program with annotations. To put it simply, use cookielib to obtain the cookie, and then use the obtained cookie to enter the website to be logged on.

#-*-Coding: UTF-8 -*-#! /Usr/bin/python import urllib2 import urllib import cookielib import re auth_url = 'HTTP: // www.nowamagic.net/'home_url = 'HTTP: // www.nowamagic.net/'; # login username and password data = {"username": "nowamagic", "password": "pass"} # urllib encoding post_data = urllib. urlencode (data) # Sending header information headers = {"Host": "www.nowamagic.net", "Referer": "http://www.nowamagic.net"} # initialize a CookieJar to process Cookie cookieJar = cookielib. cookieJar () # instantiate a global opener = urllib2.build _ opener (urllib2.HTTPCookieProcessor (cookieJar) # obtain cookie req = urllib2.Request (auth_url, post_data, headers) result = opener. open (req) # access the home page automatically with the cookie information result = opener. open (home_url) # display the result print result. read ()

A few examples are included:

1. Use existing cookies to access the website

import cookielib, urllib2  ckjar = cookielib.MozillaCookieJar(os.path.join('C:\Documents and Settings\tom\Application Data\Mozilla\Firefox\Profiles\h5m61j1i.default', 'cookies.txt'))  req = urllib2.Request(url, postdata, header)  req.add_header('User-Agent', \   'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)')  opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(ckjar) )  f = opener.open(req) htm = f.read() f.close()

2. access the website to obtain the cookie and save it in the cookie file.

 import cookielib, urllib2  req = urllib2.Request(url, postdata, header) req.add_header('User-Agent', \   'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)')  ckjar = cookielib.MozillaCookieJar(filename) ckproc = urllib2.HTTPCookieProcessor(ckjar)  opener = urllib2.build_opener(ckproc)  f = opener.open(req) htm = f.read() f.close()  ckjar.save(ignore_discard=True, ignore_expires=True)

3. Use the specified parameter to generate a cookie and use the cookie to access the website.

 import cookielib, urllib2  cookiejar = cookielib.CookieJar() urlOpener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookiejar)) values = {'redirect':", 'email':'abc@abc.com',      'password':'password', 'rememberme':", 'submit':'OK, Let Me In!'} data = urllib.urlencode(values)  request = urllib2.Request(url, data) url = urlOpener.open(request) print url.info() page = url.read()  request = urllib2.Request(url) url = urlOpener.open(request) page = url.read() print page
