Get username by user id

[hlee4real]

I want to get username by user id

Here are what I'm trying to use:

b.Handle("/check", func(c tele.Context) error {
        fmt.Println(c.Sender().ID)
        u := &tele.User{ID: 123}
        fmt.Println(u.Username)
        return nil
    })

As far as I know, you can't get username by user id. You should store username with user id somewhere if you want to get username by user id.

chat, err := b.ChatByID(893817263) if err != nil { fmt.Println(err) } fmt.Print("username:",chat.Username)
