url.Parse and values.Set

[dmitshur]

Here's the relevant documentation for url.Parse:

https://godoc.org/net/url#Parse

And (url.Values) Set:

https://godoc.org/net/url#Values.Set

There are examples that are provided by the net/url package showing some common use cases, and you can find examples of how people use url.Parse in the wild across open source repositories here.
