本文实例讲述了python实现自动登录人人网并采集信息的方法。分享给大家供大家参考。具体实现方法如下：

#!/usr/bin/python
# -*- coding: 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.file=urllib2.urlopen(req).read()    
    newsfeed = open(\'news.html\',\'w\')
    try:
      newsfeed.write(self.file)
    except Exception, e:
      newsfeed.close()
    self.operate = self.opener.open(req) 
    print type(self.operate)
    print self.operate.geturl()
    if self.operate.geturl(): 
      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(\'
(.*?)
\')#匹配范围
    apatten = re.compile(\'(.+):\')#匹配作者
    cpatten = re.compile(\'(.+)\\s\')#匹配内容 
    content = h3patten.findall(self.file)
    print len(content)  
    infocontent = self.operate.readlines()
    print type(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 = \'username\'#你的人人网的帐号
password = \'password\'#你的人人网的密码
domain = \'www.renren.com\'#人人网的地址
origURL = \'http://www.renren.com/home\'#人人网登录以后的地址
ren.setinfo(username,password,domain,origURL)
ren.login()

希望本文所述对大家的Python序设计有所帮助。
