1. GET
func Get(url string, params map[string]string, headers map[string]string) (*http.Response, error) {
//new request
req, err := http.NewRequest(http.MethodGet, url, nil)
if err != nil {
log.Println(err)
return nil, errors.New("new request is fail ")
}
//add params
q := req.URL.Query()
if params != nil {
for key, val := range params {
q.Add(key, val)
}
req.URL.RawQuery = q.Encode()
}
//add headers
if headers != nil {
for key, val := range headers {
req.Header.Add(key, val)
}
}
//http client
client := &http.Client{}
log.Printf("Go %s URL : %s \n",http.MethodGet, req.URL.String())
return client.Do(req)
}
2. POST
func Post(url string, body interface{}, params map[string]string, headers map[string]string) (*http.Response, error) {
//add post body
var bodyJson []byte
var req *http.Request
if body != nil {
var err error
bodyJson, err = json.Marshal(body)
if err != nil {
log.Println(err)
return nil, errors.New("http post body to json failed")
}
}
req, err := http.NewRequest(http.MethodPost, url, bytes.NewBuffer(bodyJson))
if err != nil {
log.Println(err)
return nil, errors.New("new request is fail: %v \n")
}
req.Header.Set("Content-type", "application/json")
//add params
q := req.URL.Query()
if params != nil {
for key, val := range params {
q.Add(key, val)
}
req.URL.RawQuery = q.Encode()
}
//add headers
if headers != nil {
for key, val := range headers {
req.Header.Add(key, val)
}
}
//http client
client := &http.Client{}
log.Printf("Go %s URL : %s \n", http.MethodPost,req.URL.String())
return client.Do(req)
}
