Go by Example: HTTP Client

The Go standard library comes with excellent support for HTTP clients and servers in the net/http package. In this example we’ll use it to issue simple HTTP requests.

package main
import (
func main() {

Issue an HTTP GET request to a server. http.Get is a convenient shortcut around creating an http.Client object and calling its Get method; it uses the http.DefaultClient object which has useful default settings.

    resp, err := http.Get("https://gobyexample.com")
    if err != nil {
    defer resp.Body.Close()

Print the HTTP response status.

    fmt.Println("Response status:", resp.Status)

Print the first 5 lines of the response body.

    scanner := bufio.NewScanner(resp.Body)
    for i := 0; scanner.Scan() && i < 5; i++ {
    if err := scanner.Err(); err != nil {
$ go run http-clients.go
Response status: 200 OK
