python cookielib 登录人人网的实现代码

请好好珍惜,因为今天是你往后日子里最年轻的一天。有了梦想,你就会有动力,有了动力,你才会有成功的希望。对待健康,偏见比无知更可怕!

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!

以上就是python cookielib 登录人人网的实现代码。心有主见,不听传言,莫论人非,过往不恋,笑对人间。更多关于python cookielib 登录人人网的实现代码请关注haodaima.com其它相关文章!
