Using HTTP/Socks5 Proxy in Go (with Username and Password)

Method 1: net/http (Most Common)

package main
import (
    "fmt"
    "io"
    "net/http"
    "net/url"
    "time"
)
func main() {
    proxyURL, _ := url.Parse("http://user:[email protected]:8080")
    transport := &http.Transport{
        Proxy: http.ProxyURL(proxyURL),
    }
    client := &http.Client{
        Transport: transport,
        Timeout:   10 * time.Second,
    }
    resp, err := client.Get("https://httpbin.org/ip")
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()
    body, _ := io.ReadAll(resp.Body)
    fmt.Println(string(body))
}

Method 2: golang.org/x/net/proxy

    // SOCKS5 authentication
    auth := &proxy.Auth{
        User:     "socksUser",
        Password: "socksPass",
    }
    // Create SOCKS5 Dialer
    socksDialer, err := proxy.SOCKS5(
        "tcp",
        "127.0.0.1:1080",
        auth,
        proxy.Direct,
    )
    if err != nil {
        panic(err)
    }
    // Inject into HTTP Transport
    transport := &http.Transport{
        DialContext: func(
