Help: How to import golang.org/x/net/proxy to use it with tcp socks5?

[sizeg]

Hello, need some help. I'm not familar with go, sorry for my question.

I've try to add "golang.org/x/net/proxy"

package main

import (
        "log"
        "os"
        "os/signal"
        "regexp"
        "strconv"
        "sync"
        "syscall"
        "time"

        "github.com/pkg/errors"
        "github.com/spf13/viper"
        tb "gopkg.in/tucnak/telebot.v2"
        "golang.org/x/net/proxy"
)

To use it with SOCKS5

func main() {
        token, e := getToken(tgtoken)
        if e != nil {
                log.Fatalln(e)
        }
        log.Printf("Telegram Bot Token [%v] successfully obtained from env variable $TGTOKEN\n", token)

        dialer, err := proxy.SOCKS5("tcp", "host:port", &proxy.Auth{User: "anon", Password:"anon"}, proxy.Direct)
    if err != nil {
        t.Fatal("Error creating dialer, aborting.")
    }

    // setup a http client
    httpTransport := &http.Transport{}
    httpClient := &http.Client{Transport: httpTransport}
    httpTransport.Dial = dialer.Dial

        var err error
        bot, err = tb.NewBot(tb.Settings{
                Token:  token,
                Poller: &tb.LongPoller{Timeout: 10 * time.Second},
                Client: httpClient
        })

And getting this error during docker-compose build. Cant google for it solution

try something like that:

import (
    "log"
    "net/http"
    "os"
    "os/signal"
    "regexp"
    "strconv"
    "sync"
    "syscall"
    "time"

    "github.com/pkg/errors"
    "github.com/spf13/viper"
    "golang.org/x/net/proxy"
    tb "gopkg.in/tucnak/telebot.v2"
)

func main() {
    token, e := getToken(tgtoken)
    if e != nil {
        log.Fatalln(e)
    }
    log.Printf("Telegram Bot Token [%v] successfully obtained from env variable $TGTOKEN\n", token)

    dialer, err := proxy.SOCKS5("tcp", "host:port", &proxy.Auth{User: "anon", Password: "anon"}, proxy.Direct)
    if err != nil {
        log.Fatalln("Error creating dialer: ", err)
    }

    // setup a http client
    httpTransport := &http.Transport{}
    httpClient := &http.Client{Transport: httpTransport}
    httpTransport.Dial = dialer.Dial

    bot, err2 := tb.NewBot(tb.Settings{
        Token:  token,
        Poller: &tb.LongPoller{Timeout: 10 * time.Second},
        Client: httpClient,
    })
    if err2 != nil {
        log.Fatalf("Cannot start bot. Error: %v\n", err)
    }

go mod vendor docker-compose build
