Golang : http.Get example

Grabbing content in raw HTML format is useful for crawling or parsing purpose. This short tutorial demonstrates how easy it is to get the content of a website with http.Get() function.

 package main

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

 func main() {

 // http.Get() can handle gzipped data response
 // automagically

 resp, err := http.Get("https://golang.org")

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

 defer resp.Body.Close()

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

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

 fmt.Println(os.Stdout, string(htmlData))

 }

run this code and if everything goes well, you should see a bunch of HTML data being printed out.

NOTE : If you encounter crypto error regarding ssl connection, upgrade your Golang to latest version if problem persists, upgrade the certs on your machine
