How to send a POST request in Go?

I am trying to make a POST request but I can't get it done. Nothing is received on the other side.

Is this how it is supposed to work? I'm aware of the PostForm function but I think I can't use it because it can't be tested with httputil, right?

hc := http.Client{}
req, err := http.NewRequest("POST", APIURL, nil)

form := url.Values{}
form.Add("ln", c.ln)
form.Add("ip", c.ip)
form.Add("ua", c.ua)
req.PostForm = form
req.Header.Add("Content-Type", "application/x-www-form-urlencoded")

glog.Info("form was %v", form)
resp, err := hc.Do(req)

You have mostly the right idea, it's just the sending of the form that is wrong. The form belongs in the body of the request.

req, err := http.NewRequest("POST", url, strings.NewReader(form.Encode()))
