本文实例讲述了Python实现模拟登录及表单提交的方法。分享给大家供大家参考。具体实现方法如下：

# -*- coding: utf-8 -*-

import re

import urllib

import urllib2

import cookielib

#获取CSDN博客标题和正文

url = "http://blog.csdn.net/[username]/archive/2010/07/05/5712850.aspx"

sock = urllib.urlopen(url)

html = sock.read()

sock.close()

content = re.findall('(?<=blogstory">).*(?=

'cm': "1"}

del content

del title

#模拟登录

cj = cookielib.CookieJar()

#用户名和密码

post_data = urllib.urlencode({'username': '[username]', 'password': '[password]', 'pwd': '1'})

#登录路径

path = 'https://passport.baidu.com/?login'

opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))

opener.addheaders = [('User-agent', 'Opera/9.23')]

urllib2.install_opener(opener)

req = urllib2.Request(path, post_data)

conn = urllib2.urlopen(req)

#获取百度发布博客的认证令牌

bd = urllib2.urlopen(urllib2.Request('http://hi.baidu.com/[username]/creat/blog')).read()

bd = re.findall('(?<=bdstoken\" value=\").*(?=ct)', bd, re.S)

blog['bdstoken'] = bd[0][:32]

#设置分类名

blog['spBlogCatName'] = 'php'

#比较表单发布博客

req2 = urllib2.Request('http://hi.baidu.com/[username]/commit', urllib.urlencode(blog))

#查看表单提交后返回内容

print urllib2.urlopen(req2).read()

#请将[username]/[password]替换为您的真实用户名和密码
