tips

• date

t := time.Now()
utc, err := time.LoadLocation("GMT") 
now := t.In(utc).Format("Wed, _2 Jul 2006 15:04:05 GMT")

• url

url := "https://211.43.177.30"
resource := "/login"

urls, _ := url.Parse(url)
urls.Path += resource

parameters := url.Values{}
parameters.Add("a", "test")
urls.RawQuery = parameters.Encode()

urlStr := urls.String()
fmt.Println(urlStr)

• json

data, _ := json.Marshal(c)
var out bytes.Buffer
json.Indent(&out, data, "", "  ")

fmt.Println(out.String())

• http

func WriteJson(w http.ResponseWriter, code int, v interface{}) error {
    w.Header().Set("Content-Type", "application/json")
    w.WriteHeader(code)
    return json.NewEncoder(w).Encode(v)
