Go server not responding properly.

I followed the example on Go docs and compiled this code for a Go server:

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hi there, I love %s!", r.URL.Path[1:])
}

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

But when I access localhost:8080 it doesn't show up anything.

Change http.ListenAndServe(":8080", nil)

to

if err := http.ListenAndServe("localhost:8080", nil); err != nil {
    log.Fatal("ListenAndServe: ", err)
}

This will force the server to only listen on the localhost interface and you won't have problems with permissions and firewall rules. It also logs any errors you may encounter.

In linux you need permission to run the program, because it is need listen on 8080 port. I am using Ubuntu, and I ran go build -o main, then I run sudo ./main, when I access the localhost:8080 it shows Hi there, I love !
