python 应用人人网

一 python人人登陆

代码如下，参考了网上的：

import re 
import urllib 
import urllib2 
import cookielib 
import datetime
import time
from urllib2 import URLError,HTTPError
#第一个参数为日志文件，第二个参数为用户名，第三个参数为密码
def renren_login(logfile,username,password):
    logfile.write(str(datetime.datetime.now()) + ' renren/r/n')
    cj = cookielib.CookieJar()
    post_data = urllib.urlencode(
        {'email':username,
         'password':password,
        }
        )
    path = 'http://www.renren.com/PLogin.do'
    opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
    urllib2.install_opener(opener)
    req = urllib2.Request(path,post_data)
    
    try:
        conn = urllib2.urlopen(req)
    except URLError,e:
        print 'URLError'
        logfile.write('URLError:' + str(e.code) + '/r/n')#http://www.renren.com/SysHome.do
        return False
    except HTTPError,e:    
        logfile.write('HTTP Error:'+e.reason + '/r/n')
        return False
    if conn.geturl() == 'http://www.renren.com/home':
        print 'success'
        logfile.write('Task finished/r/n')
        return conn.read()
    else:
        print 'Task Failed'
        logfile.write('Task failed/r/n')
# 登录成功，返回整个页面的代码       
file_object  = open("log.txt",'w')        
login_index = renren_login(file_object,'xxxxxx','xxxx')

二 python人人自动登陆，并访问最近来访者
