Go HTTP client minimal example

This example gets the current IPv4 address from TechOverflow’s IP address HTTP API How to get your current IPv4 address using wget.

package main

import (

func main() {
    // Perform request
    resp, err := http.Get("https://ipv4.techoverflow.net/api/get-my-ip")
    if err != nil {
    // Cleanup when this function ends
    defer resp.Body.Close()
    // Read all the response data into a []byte
    body, err := ioutil.ReadAll(resp.Body)
    // Decode & print

Save as Main.go in a new project directory (e.g. GoHttpTest) and run go build in that directory.
After that, you can run ./GoHttpTest which should print your IPv4 adress. Example:

uli@server ~/GoHttpTest % go build
uli@server ~/GoHttpTest % ./GoHttpTest
