Golang : Get all countries phone codes

Continue from previous tutorial where we learn how to get all the currencies names, but this time it will be the countries phone codes and un-marshall them into a map. As a challenge for you - see how can you cross reference the ISO2 codes, get the countries names and add the countries names into the list.

Here you go!

 package main

 import (
  "encoding/json"
  "fmt"
  "io/ioutil"
  "net/http"
  "os"
 )

 func main() {

  resp, err := http.Get("http://country.io/phone.json")

  if err != nil {
 fmt.Println(err)
 os.Exit(1)
  }

  defer resp.Body.Close()

  jsonPhoneCodesData, err := ioutil.ReadAll(resp.Body)

  if err != nil {
 fmt.Println(err)
 os.Exit(1)
  }

  //fmt.Println(string(jsonData))

  phoneMap := make(map[string]interface{})

  // Decode JSON into our map
  err = json.Unmarshal([]byte(jsonPhoneCodesData), &phoneMap)

  if err != nil {
 println(err)
 return
  }

  for iso2, phoneCode := range phoneMap {
 fmt.Println("ISO2 code:", iso2, "Phone code ", phoneCode)
  }

 }
