SOCKS

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

Quick Start

Get the package

go get -u "h12.io/socks"

Import the package

import "h12.io/socks"

Create a SOCKS proxy dialling 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"
	"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 := io.ReadAll(resp.Body)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(string(buf))
}

Overview

Package socks5client is imported from https://github.com/h12w/socks

Package socks implements a SOCKS (SOCKS4, SOCKS4A and SOCKS5) proxy client.

A complete example using this package:

package main

import (
	"fmt"
	"io"
	"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}

	bodyText, err := TestHttpsGet(httpClient, "https://h12.io/about")
	if err != nil {
		fmt.Println(err.Error())
	}
	fmt.Print(bodyText)
}

func TestHttpsGet(c *http.Client, url string) (bodyText string, err error) {
	resp, err := c.Get(url)
	if err != nil { return }
	defer resp.Body.Close()

	body, err := io.ReadAll(resp.Body)
	if err != nil { return }
	bodyText = string(body)
	return
}

Functions

func Dial

func Dial(proxyURI string) func(string, string) (net.Conn, error)

Dial returns the dial function to be used in http.Transport object. Argument proxyURI should be in the format: "socks5://user:password@127.0.0.1:1080?timeout=5s". The protocol could be socks5, socks4 and socks4a.

func DialSocksProxy

func DialSocksProxy(socksType int, proxy string) func(string, string) (net.Conn, error)

DialSocksProxy returns the dial function to be used in http.Transport object. Argument socksType should be one of SOCKS4, SOCKS4A and SOCKS5. Argument proxy should be in this format "127.0.0.1:1080".
