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.

Go
Edit 
package main

import (
    "bufio"
    "fmt"
    "net/http"
)

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("http://gobyexample.com")
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

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

    scanner := bufio.NewScanner(resp.Body)
    for i := 0; scanner.Scan() && i < 5; i++ {
        fmt.Println(scanner.Text())
    }

    if err := scanner.Err(); err != nil {
        panic(err)
    }
}
