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 datetimeimport timefrom 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。
