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。
