-A QueryString is, by definition, in the URL. You can access the URL of the request using req.URL (doc). The URL object has a Query() method (doc) that returns a Values type, which is simply a map[string][]string of the QueryString parameters.
-
-If what you're looking for is the POST data as submitted by an HTML form, then this is (usually) a key-value pair in the request body. You're correct in your answer that you can call ParseForm() and then use req.Form field to get the map of key-value pairs, but you can also call FormValue(key) to get the value of a specific key. This calls ParseForm() if required, and gets values regardless of how they were sent (i.e. in query string or in the request body).

-req.URL.RawQuery returns everything after the ? on a GET request, if that helps.
