[Go]HTTP client and read the contents of a http body

This is a simple program that gets the response body of google.com. The response is returned and stored in resp, then ioutil.ReadAll() reads resp.Body. The resp.Body will then be converted into string and output by fmt.Println.

package main

import (
	"fmt"
	"io/ioutil"
	"log"
	"net/http"
	"strings"
)

func main() {
	resp, err := http.Get("http://google.com")
	// error handling
	if err != nil {
		log.Fatal(err)
	}

	// ioutil.ReadAll returns a byte slice and an error.
	// b is the byte slice which holds the content in resp.Body.
	b, e := ioutil.ReadAll(resp.Body)
	// error handling
	if e!= nil {
		log.Fatal(e)
	}
	// Print out the output with unwanted spaces trimmed.
	fmt.Println(strings.TrimSpace(string(b)))
}
