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('<article>(.*?)</article>')#匹配范围
    apatten = re.compile('<h3.+>(.+)</h3>:')#匹配作者
    cpatten = re.compile('</a>(.+)\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()
