58同城的登录是使用的Post提交方法，提交原文章是这样的

isweak=1&path=http%3A%2F%2Fxa.58.com%2F%3Fpts%3D1356513306818&p1=d25fbcbee8542bf546fbb8e54219d106&p2=f628477367385fe52c7fd1886c30ce4c×ign=1356513341009&ptk=e3741580635e4fd8aab83345a3433853&cd=8739&username=用户名&password=password

复制代码

里面是没有密码是，而是使用JS进行的加密p1,p2就是加密后的数据，
那这个是使用一个JS文件来加密的，JS文件如下

现在最关键的是怎么在C#里执行JS方法，
我们先在自己的项目里添加两个引用看下图

然后看我的代码吧

对象就安对象处理，不能直接Tostring，这个要具体情况具体分析了

知道怎么处理呢现在的问题是js文件不唯一，也是根据时间和其他参数生成的，而js里面又有动态口令..够折腾的
