python cookielib 登录人人网的实现代码
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://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(\'
(.*?)
\’)#匹配范围apatten = re.compile(\'
cpatten = re.compile(\'(.+)\\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!
