How te send a POST with both URL parameters and a JSON body? [closed]

Question

I found how to send a POST with URL parameters, or how to send a POST with a JSON body, but I do not know how to combine them together (a request with both a URL with parameters, and a JSON body).

The code below (which is not correct) shows the commbination I am looking for. I can use either bytes.NewBuffer(jsonStr) or strings.NewReader(parm.Encode()) but not both.

package main import ( "bytes" "net/http" "net/url" "strings" ) func main() { var jsonStr = []byte(`{"title":"my request"}`) parm := url.Values{} parm.Add("token", "hello") req, err := http.NewRequest("POST", "https://postman-echo.com/post", bytes.NewBuffer(jsonStr), strings.NewReader(parm.Encode())) if err != nil { panic(err) } req.Header.Set("Content-Type", "application/json") client := &http.Client{} resp, err := client.Do(req) if err != nil { panic(err) } defer resp.Body.Close() }

How to build a full POST call with all the components?

I don't think you should be trying to send the URL parameters in the request body. As you say, you can't use both (because an HTTP request is meant to have a single body, the URL is separate). — Hymns For Disco

Those aren't URL parameters. URL parameters, by definition, are parameters to the URL. — Jonathan Hall

@Flimzy yes I know, I am starting with Go and trying to port what I know from Python where a single call gets both the parameters and the body. — WoJ

Curious. If you know that, I wonder why you said otherwise in your question. — Jonathan Hall

@Flimzy " ... is not URL parameters" ahhhh, ok. I was reading a page where parm was used for both the body and the URL (in different examples) - this is where I got it wrong. — WoJ

Use the only json as your request body, and apply the URL parameters like this:

req.URL.RawQuery = parm.Encode()

From Go doing a GET request and building the Querystring
