Basic Http : Tutorial Golang Bahasa Indonesia

tutorialgolang3.txt

1. Menambahkan HTTP Package
http.HandleFunc("/", func(writer http.ResponseWriter, request *http.Request) {
  fmt.Fprint(writer, "test browser")
})
http.ListenAndServe(":8080", nil)

2. Create Enpoint (untuk ujicoba)
http.HandleFunc("/test", otherFunc)

3. Http Verb
func otherFunc(writer http.ResponseWriter, request *http.Request) {
  switch request.Method {
    case "POST":
  }
	if  == "POST" {
	} else {

		http.Error(writer, "Invalid request method, you use " + queryValues.Get("username"), http.StatusMethodNotAllowed)
	}
}
4. Membaca Arguments / Params (Path, Query, Body)
  #Field 
  Formrequest.FormValue("field")
  
  #Queries
  queryValues := request.URL.Query()
  queryValues.Get("field")
  
  #Path
  request.URL.Path[len("/endpoint/"):]
  
  #Body
  type LoginBody struct {
    Username string `json:"username"`
    Password string `json:"password"`
  }
  b, err := ioutil.ReadAll(request.Body)
	defer request.Body.Close()
  var reqs LoginBody
	err = json.Unmarshal(b, &reqs)
  // reqs sudah bisa digunakan
  
5. Membuat Response ()
  http.Error(writer, "invalide method", http.StatusMethodNotAllowed)
  
  //Json Response
  responseWithMap := map[string]interface{}{
    "data" : "what?",
    "status" : http.StatusOK,
   }

  writer.Header().Set("Content-Type", "application/json")
  writer.WriteHeader(http.StatusOK)
  json.NewEncoder(writer).Encode(responseWithMap)
  return
