使用爬虫来模拟smart qq的登录，能使用你的java来开发一款聊天机器人哦，cool！

首先介绍一下使用的技术：httpclient,jsoup
smart qq地址:http://w.qq.com/
项目的百度云盘地址：http://pan.baidu.com/s/1mhSmfQ4
说一下我的思路：首先仔细的分析smart qq页面的请求，然后就开始开发吧

由于smart qq写出来并没有什么利润，只能用来好玩，因此我就纯玩，也不太注意编码格式，要注意的是，需要使用qq去扫描下载下来的二维码图片哦，此亦有一个叫iqq的开源项目，也是模拟的smart qq来开发的，由于cookie的问题，或者说bug吧，你需要使用浏览器在你本机上先登录上smart qq，然后才能使用本程序去登录，据说是cookie跨域的问题（iqq项目也有此问题），我也懒的搞，因为这个东西是我好久之前写的，我还写了微信的扫码登录，由于是web版本的，赚不了啥子钱，就写成功了，挑战一下企鹅公司的技术，就基本的放弃的开发与维护，如果有谁感兴趣，可以留言询问哦
