python人人网登录应用实例

本文实例讲述了python人人网登录应用的实现方法，分享给大家供大家参考。

具体方法如下：

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\')

希望本文所述对大家的Python程序设计有所帮助。
