package socks implement a socks4/4a/5 protocol server and client
|
|
|
|
only support CONNECT command now
|
|
|
|
server example:
|
|
|
|
// listen 1080 and act as socks server
|
|
// support socks4, socks4a and socks5
|
|
|
|
package main
|
|
|
|
import (
|
|
socks "github.com/fangdingjun/socks-go"
|
|
"log"
|
|
"net"
|
|
"time"
|
|
)
|
|
|
|
func main() {
|
|
conn, err := net.Listen("tcp", ":1080")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
for {
|
|
c, err := conn.Accept()
|
|
if err != nil {
|
|
log.Println(err)
|
|
continue
|
|
}
|
|
|
|
log.Printf("connected from %s", c.RemoteAddr())
|
|
|
|
d := net.Dialer{Timeout: 10 * time.Second}
|
|
s := socks.Conn{Conn: c, Dial: d.Dial}
|
|
go s.Serve()
|
|
}
|
|
}
|
|
|
|
|
|
|
|
|
|
client example:
|
|
|
|
// visit https://www.google.com through socks proxy server
|
|
|
|
package main
|
|
|
|
import (
|

|
"io"
|
|
"log"
|
|
"net"
|
|
"net/http"
|
|
"os"
|
|
)
|
|
|
|
func main() {
|
|
// connect to socks server
|
|
c, err := net.Dial("tcp", "localhost:1080")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer c.Close()
|
|
|
|
sc := &socks.Client{Conn: c}
|
|
|
|
// connect to remote server
|
|
if err := sc.Connect("www.google.com", 443); err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
// tls
|
|
conn := tls.Client(sc, &tls.Config{ServerName: "www.google.com"})
|
|
if err := conn.Handshake(); err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
// send http request
|
|
req, err := http.NewRequest("GET", "https://www.google.com/", nil)
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
req.Write(conn)
|
|
|
|
bio := bufio.NewReader(conn)
|
|
|
|
// read response
|
|
res, err := http.ReadResponse(bio, req)
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer res.Body.Close()
