我对打n并不熟悉，但是使用Golang的
net/http程序包可以很好地工作（游乐场）：
func main() { url := "http://restapi3.apiary.io/notes" fmt.Println("URL:>", url) var jsonStr = []byte(`{"title":"Buy cheese and bread for breakfast."}`) req, err := http.NewRequest("POST", url, bytes.NewBuffer(jsonStr)) req.Header.Set("X-Custom-Header", "myvalue") req.Header.Set("Content-Type", "application/json") client := &http.Client{} resp, err := client.Do(req) if err != nil { panic(err) } defer resp.Body.Close() fmt.Println("response Status:", resp.Status) fmt.Println("response Headers:", resp.Header) body, _ := ioutil.ReadAll(resp.Body) fmt.Println("response Body:", string(body))}
