Integrating Clash in Golang Programs ​

If clash does not fit your own usage, you can use Clash in your own Golang code.

There is already basic support:

package main

import (
    "context"
    "fmt"
    "io"
    "net"

    "github.com/Dreamacro/clash/adapter/outbound"
    "github.com/Dreamacro/clash/constant"
    "github.com/Dreamacro/clash/listener/socks"
)

func main() {
    in := make(chan constant.ConnContext, 100)
    defer close(in)

    l, err := socks.New("127.0.0.1:10000", in)
    if err != nil {
    	panic(err)
    }
    defer l.Close()

    println("listen at:", l.Address())

    direct := outbound.NewDirect()

    for c := range in {
    	conn := c
    	metadata := conn.Metadata()
    	fmt.Printf("request incoming from %s to %s\n", metadata.SourceAddress(), metadata.RemoteAddress())
    	go func () {
    		remote, err := direct.DialContext(context.Background(), metadata)
    		if err != nil {
    			fmt.Printf("dial error: %s\n", err.Error())
    			return
    		}
    		relay(remote, conn.Conn())
    	}()
    }
}

func relay(l, r net.Conn) {
    go io.Copy(l, r)
    io.Copy(r, l)
}
