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\">).*(?=
.*(.*)\', content[0], re.S) 
title = re.findall(\'(?<=)\', html, re.S) 
#根据上文获取内容新建表单值 
blog = {\'spBlogTitle\': title[0].decode(\'utf-8\').encode(\'gbk\'), #百度博客标题 
    \'spBlogText\': content[0].decode(\'utf-8\').encode(\'gbk\'),#百度博客内容 
    \'ct\': \"1\", 
    \'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
