net/http 패키지에 Get() Post() 명령등을 사용하면 간단하게 보낼수 있는 듯.

resp, err := http.Get("http://example.com/")
...
resp, err := http.Post("http://example.com/upload", "image/jpeg", &buf)
...
resp, err := http.PostForm("http://example.com/form",
	url.Values{"key": {"Value"}, "id": {"123"}})

Put() Delete()는 http.NewRequest()를 이용하여 http.MethodPut / http.MethodDelete 타입으로 만들어 주면

기본 모듈로도 충분히 구현 가능한 것 같다.

func put() {     fmt.Println("3. Performing Http Put...")     todo := Todo{1, 2, "lorem ipsum dolor sit amet", true}     jsonReq, err := json.Marshal(todo)     req, err := http.NewRequest(http.MethodPut, "https://jsonplaceholder.typicode.com/todos/1", bytes.NewBuffer(jsonReq))     req.Header.Set("Content-Type", "application/json; charset=utf-8")     client := &http.Client{}     resp, err := client.Do(req)     if err != nil {         log.Fatalln(err)     }     defer resp.Body.Close()     bodyBytes, _ := ioutil.ReadAll(resp.Body)     // Convert response body to string     bodyString := string(bodyBytes)     fmt.Println(bodyString)     // Convert response body to Todo struct     var todoStruct Todo     json.Unmarshal(bodyBytes, &todoStruct)     fmt.Printf("API Response as struct:\n%+v\n", todoStruct) } func delete() {     fmt.Println("4. Performing Http Delete...")     todo := Todo{1, 2, "lorem ipsum dolor sit amet", true}     jsonReq, err := json.Marshal(todo)     req, err := http.NewRequest(http.MethodDelete, "https://jsonplaceholder.typicode.com/todos/1", bytes.NewBuffer(jsonReq))     client := &http.Client{}     resp, err := client.Do(req)     if err != nil {         log.Fatalln(err)     }     defer resp.Body.Close()     bodyBytes, _ := ioutil.ReadAll(resp.Body)     // Convert response body to string     bodyString := string(bodyBytes)     fmt.Println(bodyString) }
