How to generate deeply nested fields for api request using url.Values?

Using the url package https://golang.org/pkg/net/url/#pkg-overview, one can create some data to send in an api request like so (referencing this post):

hc := http.Client{}  req, err := http.NewRequest("POST", APIURL, nil)    form := url.Values{}  form.Add("ln", "value")  form.Add("ip", "value2")  form.Add("ua", "value3")  req.PostForm = form  req.Header.Add("Content-Type", "application/x-www-form-urlencoded")    glog.Info("form was %v", form)  resp, err := hc.Do(req)  

My question is, how can one send nested json values? Something like:

form.Add("ln", {"nestedKey": nestedvalue})  

Is this possible? How can one send nested values? More generally, how can one send a json body in a request?
