先上脚本吧，等下来讲下知识点:
复制代码 代码如下:
#!/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://"; 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!
