python实现自动登录人人网并访问最近来访者实例

本文实例讲述了python实现自动登录人人网并访问最近来访者的方法，分享给大家供大家参考。

具体方法如下：

##-*- coding : gbk -*- #在 import os from xml.dom import minidom  import re  import urllib  import urllib2  import cookielib  import datetime import time from urllib2 import URLError,HTTPError #登录模块　在网上找的 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')     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')     open('login_renren.html','w').write(conn.read())     return conn.read()   else:     print 'Task Failed'     logfile.write('Task failed/r/n') #生成的登录日志文件     file_object = open("log.txt",'w')     login_index = renren_login(file_object,'用户名','密码')　#这地方换成登录的用户名和密码   #parse　解析网页 r1 = re.compile('''''http://www.renren.com/profile.do/?portal=homeFootprint&ref=home_footprint&id=/d{9}''') li = r1.findall(open("login_renren.html","r").read()) #将解析到的最近来访的地址放入字典中url_dict ={}for item in li: print item url_dict.setdefault(item) #访问最近来访者for item in url_dict.iterkeys(): os.startfile(item) 

希望本文所述对大家的Python程序设计有所帮助。
