SOCKS

A SOCKS is a SOCKS4, SOCKS4A and SOCKS5 proxy package for Go.

The package provides socks.Dial which returns a TCP dialing function from a socks proxy connection string. The returned dialing function can then be used to establish a TCP connection via the socks proxy or be used to initialize http.Transport for an HTTP connection.

Quick Start

Get the package

go get -u "h12.io/socks"

Import the package

import "h12.io/socks"

Create a SOCKS proxy dialing function

dialSocksProxy := socks.Dial("socks5://127.0.0.1:1080?timeout=5s")
tr := &http.Transport{Dial: dialSocksProxy}
httpClient := &http.Client{Transport: tr}

User/password authentication

dialSocksProxy := socks.Dial("socks5://user:password@127.0.0.1:1080?timeout=5s")

Example

package main

import (
	"fmt"
	"io/ioutil"
	"log"
	"net/http"

	"h12.io/socks"
)

func main() {
	dialSocksProxy := socks.Dial("socks5://127.0.0.1:1080?timeout=5s")
	tr := &http.Transport{Dial: dialSocksProxy}
	httpClient := &http.Client{Transport: tr}
	resp, err := httpClient.Get("http://www.google.com")
	if err != nil {
		log.Fatal(err)
	}
	defer resp.Body.Close()
	if resp.StatusCode != http.StatusOK {
		log.Fatal(resp.StatusCode)
	}
	buf, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(string(buf))
}
