Best handle of http response?

Getting Help
1

A standard http req like:

	data, _ := json.Marshal(map[string]any{
		"passwd": "123",
		"name":   "xx",
	})
	req, err := http.Post("http://localhost:8085/login", "application/json", bytes.NewReader(data))
	if err != nil {
		panic(err)
	}
	defer req.Body.Close()
	io.Copy(io.Discard, req.Body) // must ?

I need do many http requests.If i don’t care respone ,should i use io.Copy(io.Discard, req.Body) ?
I see some articles says resp.Body.Close() will reads and discards the remaining response body data.

Just close the body directly, you don’t need to think too much.
