python cookielib 登录人人网的实现代码

先上脚本吧，等下来讲下知识点:

#!/usr/bin/env python 
#encoding=utf-8 
import sys 
import re 
import urllib2 
import urllib 
import cookielib class Renren(object): 
def __init__(self): 
self.name = self.pwd = self.content = self.domain = self.origURL = '' 
self.operate = ''#登录进去的操作对象 
self.cj = cookielib.LWPCookieJar() 
try: 
self.cj.revert('renren.coockie') 
except Exception,e: 
print e 
self.opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(self.cj)) 
urllib2.install_opener(self.opener) 

def setinfo(self,username,password,domain,origURL): 
'''设置用户登录信息''' 
self.name = username 
self.pwd = password 
self.domain = domain 
self.origURL = origURL 
def login(self): 
'''登录人人网''' 
params = {'domain':self.domain,'origURL':self.origURL,'email':self.name, 'password':self.pwd} 
print 'login.......' 
req = urllib2.Request( 
'http://www.renren.com/PLogin.do', 
urllib.urlencode(params) 
) 
self.operate = self.opener.open(req) 
if self.operate.geturl() == 'http://www.renren.com/Home.do': 
print 'Logged on successfully!' 
self.cj.save('renren.coockie') 
self.__viewnewinfo() 
else: 
print 'Logged on error' 
def __viewnewinfo(self): 
'''查看好友的更新状态''' 
self.__caiinfo() 

def __caiinfo(self): 
'''采集信息''' 
h3patten = re.compile('<h3>(.*?)</h3>')#匹配范围 
apatten = re.compile('<a.+>(.+)</a>:')#匹配作者 
cpatten = re.compile('</a>(.+)\s')#匹配内容 
infocontent = self.operate.readlines() 
# print infocontent 
print 'friend newinfo:' 
for i in infocontent: 
content = h3patten.findall(i) 
if len(content) != 0: 
for m in content: 
username = apatten.findall(m) 
info = cpatten.findall(m) 
if len(username) !=0: 
print username[0],'说:',info[0] 
print '----------------------------------------------' 
else: 
continue 
ren = Renren() 
username = ''#你的人人网的帐号 
password = ''#你的人人网的密码 
domain = 'renren.com'#人人网的地址 
origURL = 'http://www.renren.com/Home.do'#人人网登录以后的地址 
ren.setinfo(username,password,domain,origURL) 
ren.login()

主要用到了python cookielib,urllib2,urllib这3个模块，这3个模块是python做http这方面比较好的模块.

self.cj = cookielib.LWPCookieJar()

try:
self.cj.revert('renren.coockie')
except Exception,e:
print e
self.opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(self.cj))

urllib2.install_opener(self.opener)
这几行是在本地建立人人网的cookies，因为人人网要验证cookies才能登录，你运行这个脚本的话，会发现在当前目录 有个程序会自动建立一个renren.cookie这个文件。

我这里renren.cookie的信息是: #LWP-Cookies-2.0 Set-Cookie3: WebOnLineNotice_244225225=1; path="/"; domain=".renren.com"; path_spec; domain_dot; expires="2010-04-11 06:59:33Z"; version=0 总结一下如果网站登录要用cookie的话，就要用到cookielib这个模块，不然你用程序登录不了网站,过断时间在写个urlib的例子，大家可以先用上面这个脚本玩玩!体会下python 人人网代码的乐趣!
