About Transparent Proxy about gomitmproxy HOT 5 OPEN

I'm desperately asking for help right now, I can only hope for now

from gomitmproxy.

I extracted a simple example of the core http proxy of the gomitmproxy, which is printed normally in http

func main() {
	listenAddr := &net.TCPAddr{
		IP:   net.IPv4(0, 0, 0, 0),
		Port: 8080,
	}
	l, err := net.ListenTCP("tcp", listenAddr)
	if err != nil {
	}
	log.Printf("start listening to %s", l.Addr())

	conn, err := l.Accept()
	log.Printf("remote addr is %s", conn.RemoteAddr())
	log.Printf("local addr is %s", conn.LocalAddr())

	localRW := bufio.NewReadWriter(bufio.NewReader(conn), bufio.NewWriter(conn))

	var req *http.Request
	reqc := make(chan *http.Request, 1)
	errc := make(chan error, 1)

	go func() {
		r, err := http.ReadRequest(localRW.Reader)
		if err != nil {
			errc <- err
			return
		}
		reqc <- r
	}()

	req = <-reqc

	log.Println(req)
}

It can be obtained normally, but if the proxy is transparent, how should this code be changed?

If the official can give a simple example of modification, it would be great, thank you very much

Well, the problem is that currently it simply does not support the transparent proxy approach, it expects to be used as a normal proxy. The code requires substantial changes to support this.

If you add a transparent proxy, roughly what you need to do? Is it first to initiate a CONNECT request to gomitmproxy through TCP for iptable traffic, when encountering HTTPS traffic? It seems that if a third-party transparent proxy (support upstream is HTTP https://github.com/xiqingping/transproxy) is connected between iptable and gomitmproxy, it can be used, but I want to integrate the transparent proxy function into gomitmproxy (this way I don’t need to open another program), but due to my limited personal ability, I can’t implement it yet. Can the author provide some ideas?
