Go output with ioutil: returning array of (ASCII?) numbers from http call

Question

I am trying to write a web client in Go, but when I check the return value of the body of the http request, I get an array of numbers, instead of text.

This is the most isolated version of the program that produces the output. I think I am failing do something with ioutil, but do not know what.

package main

import "fmt"
import "net/http"
import "io/ioutil"

func main() {
    resp, err := http.Get("http://test.com/")
    if err != nil {
        fmt.Println(err)
    }
    defer resp.Body.Close()
    body, err := ioutil.ReadAll(resp.Body)
    fmt.Print(body)
}

The output comes out looking like:

[239 187 191 60 33 68 79 67 84 89 80 69 32 104 116 109 108 ...

instead of the test returned by test.com

ioutil.ReadAll() returns a byte slice ([]byte) and not a string (plus an error).

Convert it to string and you're good to go:

fmt.Print(string(body))

See this simple example (try it on Go Playground):

var b []byte = []byte("Hello")

fmt.Println(b)
fmt.Println(string(b))

Output:

[72 101 108 108 111]
Hello
