android+httpclient打造cjol客户端

问题背景：媳妇要找工作，简历发在cjol上。这几点是她最关心的内容：1、刷新简历（网站的功能，能改变简历发布时间让简历排在前面）  2、面试通知 3、简历浏览数  但她大部分时间都是要在外边面试。所以这3项工作自然就落到我的头上，每半小时就一个电话过来监督，好烦人。于是，动手能力一向很强的本人决定从问题出发，给cjol做个客户端，解决她以上需求。

要点：1、模拟http请求 2、解析html

难度：2颗小星星

工具：

1）Fiddler2 用他来监控浏览器和服务器间的所有请求，找到关键操作 http://www.cnblogs.com/chenjiajin/archive/2011/12/15/2288786.html

2）httpclient  Apache 出品必属精品，提供HTTP 协议的客户端编程工具包。用来模拟http请求

3）android环境

找出关键步骤了，剩下的就是模拟了。接着录下刷新、打开面试通知页面等步骤。用httpclient模拟即可。

搞完收工。媳妇一脸的崇拜，获赠香吻一枚。之后，接电话接到手软。嘻嘻~~两天后，搞定工作！

总结：以上只是简单的实现，就一个activity，但发挥想象力，利用httpclient模拟http请求能做的事情还是很多的， 比如自动刷票、投票、签到。。。浏览器上能做的事情，都可以实现。
