发一个自己写的秒杀参与程序，纯分享，无他用。

秒杀：准点开抢，先抢先得。
页面上的操作流程大致是这样的：登录->填写用户资料->等待倒计时->弹出随机问题->填写答案->提交。
前两步人工完成，程序完成从等待倒计时到提交结束的步骤。主要使用httpclient模拟http请求。前期工作主要研究下原站的相关js代码，获得各步骤必要的URL和相关参数。其中还用到了坛子里的fastjson感谢一下 。

主要代码如下，就不做什么解释了。

现在活动结束了，发上来大家围观一下吧。

用这个 https://ladyr.es/ladyrbrowser/ 或者 HtmlUnit 只需要模拟浏览器操作，触发个onclick事件就可以 

ladyrbrowser 有性能问题需要优化 ，HtmlUnit  执行js比较慢。。。


以前做舆情监控的时候就是用的ladyrbrowser(需要js构建Dom) 和 HttpClient

透露透露,go共都干了些什么

LZ用这个称到东西吗？ 

不定时秒杀的那种有效吗？

当然。

有验证码的能搞不？

我想知道抢到了神马？

同问抢啥的？

  很受启发，但是将代码拷贝到新建的工程后出现了很多错误，无法测试，能否发一个完整的项目学习一下？十分感谢！
