How can I solve problem of 404 page display?

Question

I have the function for the main page, which contains 'if' part for the 404 error page:

// Обработчик главной страницы
func home(w http.ResponseWriter, r *http.Request)  {
    w.Write([]byte("Is it alive?"))
    // Создание страницы 404
    if r.URL.Path != "/" {
        http.NotFound(w, r)
        return
    }
}

But when I go to the unable page ('127.0.0.1:4000/nothing' for example), I get back both parts - and message "is it alive?" and "404 page not found": So, what can I do to solve it?

Answer 1

func home(w http.ResponseWriter, r *http.Request)  {
    // Создание страницы 404
    if r.URL.Path != "/" {
        http.NotFound(w, r)
        return
    }

    w.Write([]byte("Is it alive?"))
}
