Easy to Go

socks5

...
func server(){
    ln,err := socks5.Listen("tcp", ":1080",nil)
    if err != nil { panic(err) }
    // hostPort为client请求代理的地址
    conn,hostPort,err := ln.Accept()
    if err != nil { panic(err) }
    go relay(conn,hostPort)... // 代理连接
}
func client(){
    // 通过socks5协议代理www.google.com:443
    conn,err := socks5.Dial("tcp","your_server.com:1234","www.google.com:443",nil)
    if err != nil { panic(err) }
    conn.Write([]byte("GET / HTTP/1.1\r\nHost: www.google.com\r\n\r\n"))
    ...
}

trojan

func server(){
    tlsConfig := &tls.Config{...} // 配置tls

    if err == nil { ... //代理连接 }
    if err, ok := err.(trojan.AuthFailure); ok {

        // 重定向连接到网页
        // []byte(err) 为 trojan 已经读取的数据流
        go Redirect(conn, []byte(err))
        continue

• 所有包实现和net库一致接口Dial,Listen...
• 高聚合低耦合,基本只使用官方标准库,其余逻辑都内部自实现

ToDo

• Socks5
• Shadosocks
• Trojan
• Vmess
• Websocket
