Header golang client get

Usually how to tech is

req, err := http.NewRequest("GET", "http://example.com", nil)

req.Header.Add("Authorize", "dswxswsxw")

resp, err := client.Do(req)

BUT  Have problem inside. So.... use this

headers := http.Header{
"Accept-Encoding": []string{"gzip, deflate"},
}

req, err := http.NewRequest("GET", url, nil)
req.Header = headers

client := &http.Client{}
resp, err = client.Do(req)

More Safe.
