超级技巧：把局部代理变成全局VPN

我们有时会遇到需要全局VPN的情况，比如开CMD窗口:需要做GOAPP部署的时候,或者git clone 某些被GFW墙掉的网址时，必须要全局VPN，否则网址无法访问,CMD默认是直连的，不走代理，就算用set 设置了http/https proxy，也没用。

这时候怎么办，要么用VPN Gate,要么买VPN(别便宜了这些卖VPN的)

proxycap可以帮助你解决这问题，proxycap比proxifier更好用，不太占系统资源。

具体方法： 下载proxycap,然后新建一个proxyserver:127.0.0.1:1080(SS代理端口)。
然后新建规则： a. SS走直连 b.其他所有程序redirect throught proxy走代理。

这样就把局部代理变成了全局代理，相当于全局VPN,

下面是测试效果（未开VPN就能部署成功）
