req, _ := http.NewRequest("GET", url, payload)
req.Header.Add("content-type", "application/json")
type Params struct {
auth string

func doIt(p Params) string {

res, _ := http.DefaultClient.Do(req)
defer res.Body.Close()
body, _ := ioutil.ReadAll(res.Body)
fmt.Println(res)
fmt.Println(string(body))
