开心网辅助程序开发手记2011-12-13 博客园 jailu声明：本人只在业余空闲时间写写《开心网辅助程序》，目的只是学习！由于之前有写过类似的程序，也写过相关的文章介绍过（C#网站登录学习笔记（一）：登录简单网站、C#网站登录学习笔记（二）：访问需登录后才能访问的页面），这次写起“开心网辅助程序”也可以算是得心应手了，直接从电脑中翻出尘封已久的HttpHelper（前面提到的两篇文章就是居于这个操作类进行的），稍微分析了一下网页结构（争车位），就写起程序来了！在开始写手记前，让我们看看写这样的“外挂”程序需要准备什么软件？1. 抓包工具：Http Analyzer V3。既然要实现的是Http模拟请求，抓包工具肯定少不了了2. 网页分析工具：Firefox 3.0 + Firebug 1.2.1。没错，可爱的火狐狸又来帮忙了在这篇手记中，将简单的介绍一下如何登录开心网、获取争车位相关数据。一、稍微修改了一下HttpHelper类的代码：Code
