Correct HTTP GET response handling

httpGet.go

res, err := http.GET(...)
if res != nil {
    defer func() {
        _, err = io.Copy(ioutil.Discard, res.Body)
        res.Body.Close()
    }()
}
if err != nil {
    // . . . 
}

Adding a timeout to Get. By default there is no timeout.

client := http.Client{Timeout: time.Minute}
res, err := client.Get("...")
if res != nil {
    defer res.Body.Close()
}
if err != nil {
    log.Fatal(err)
}
b, _ := ioutil.ReadAll(res.Body)
...
