将TCP放到WebSocket中传输（就能走CDN）基于ws的内网穿透 隧道代理 tcp2ws

Tcp over WebSocket (TCP to WebSocket)

本工具能 使用WebSocket创建隧道，实现TCP端口转发

至于这样脱裤子放屁的操作有什么用？

举个例子，一个服务器只能通过cdn的http转发，它也不能联网，这时你就可以利用此工具将需要转发的端口（比如22）转换成ws协议（http）来传输，再去Nginx里面配一个反代，那么当本客户端访问Nginx提供的服务的特定路径时将反代到本服务端，实现内网穿透进行端口转发
这时防火墙仅仅发现你连接了一个WebSocket而已

如何使用

在右边Releases中选择你使用的平台的程序来运行
服务端：tcp2ws 要代理的ip:端口 本ws服务的监听端口
客户端：tcp2ws ws://链接 本地监听端口

举个 🌰 ：
在服务器运行tcp2ws 127.0.0.1:22 22222
然后在nginx中反代了一下
在客户端运行ws://yourdomain.com/ssh 222
那么就可以通过客户端的222来访问服务器的ssh啦
是不是特别棒呢

速度

在Windows使用本工具来回转换iperf3端口测试得到的数据
