Sometimes our services can only expose the 80/443 interface to provide http services, but we may need to access other services in the server, such as mysql, consul, etc. So how can we open only http/https ports and still What about services that access other ports on the server?

We can use websocket to proxy the tcp port, so that we can access all traffic based on the tcp protocol, so I wrote a go-based traffic proxy.

Get dependencies

go get github.com/MikeLINGxZ/http2tcp

Add handler method to http route

package main

import (
	"github.com/MikeLINGxZ/http2tcp"
	"net/http"
)

func main() {
    http.HandleFunc("/path",http2tcp.ProxyForHttpHandler("your-password"))
	http.ListenAndServe(":8080", nil)
}
