分析网址：http://219.142.101.79/regist/wfRegister.aspx?type=1

第一步还是抓包看post数据问题。

   从这个数据看出变化的值有__EVENTTARGET，__VIEWSTATE，__EVENTVALIDATION。那其他变量值都是一样的，其实__EVENTTARGET这个值也是固定不变的，是下一页的一个识别码，那就剩下了两个变量值变化，也就是说，这个网址是没有我们常见的分页变量值进行处理的，而它们每一页数据处理都是通过 __VIEWSTATE，__EVENTVALIDATION这两个变量值进行处理的，也就是每一次分页，就会获取这一页内的两个随机值进行组合后，处理下一页的数据的。

 这个网址分页数据的采集分析就到这里，后面的采集方法就看自己的编程基础，或者使用相关软件进行处理就可以了。
