crossGFW玩具档案

这是一个玩具脚本，能在windows和linux上面跑。当时有一个网站提供免费的ss账号，但是账号、密码会定时变更，所以写了这个脚本来爬取免费vpn账号，然后配置好参数，最后双击启动shadowsocks。
好傻吊的玩具，被我校招时一直写简历上面，哈哈。放在 repo 里面，感觉不值得，以文章的形式留个纪念吧！

入口

入口很简单，双击 sss.bat 脚本，代理就自己挂上了。但是貌似在jar包里面也启动了ss代理，搞不懂啊。

抓取免费账号

现在的疑问为什么当时不用Python写，非得用Java。

此处的入口是一个Main方法，它主要抓取免费账号、填充vpn配置和启动ss。

    }

没搞明白当时的想法，我为啥还定义了一个 Server POJO类，代码里面并没见到调用呀。

启动ss

最魔幻的事情还是发生了，与sss.bat里面的代码貌似有点冲突。

也许是后面加的Java代码，但是 who cares，反正它也没有什么实际价值与维护的意义，当做纪念吧~
