今天晚上不是很忙,所以早早的就在电脑的旁边开始写东西了。我今天给大家分享一个我自己用python写的自动登录 人人网的脚本,没办法就是懒!懒的输入帐号和密码,让python给我们减少工作量! 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! 如果你对web方面有兴趣的话,可以看看: 使用python BeautifulSoup 解析网页 , python beautifulsoup多线程分析抓取网页
