How can I translate this IDNA URL to Unicode?

I want to translate an IDNA ASCII URL to Unicode.

package main
import (
	"golang.org/x/net/idna"
	"log"
)
func main() {
	input := "https://xn---36-mddtcafmzdgfgpbxs0h7c.xn--p1ai"
	idnaProfile := idna.New()
	output, err := idnaProfile.ToUnicode(input)
	if err != nil {
		log.Fatal(err)
	}
	log.Printf("%s", output)
}

The output is: https://xn---36-mddtcafmzdgfgpbxs0h7c.рф

It seems the IDNA package only converts the TLD. Is there some option that can convert the full URL?

I need to get the same result as when I paste the ASCII URL into Chrome:
https://природный-источник36.рф

You simply need to parse the URL first:

package main
import (
   "golang.org/x/net/idna"
   "net/url"
)
func main() {
   p, e := url.Parse("https://xn---36-mddtcafmzdgfgpbxs0h7c.xn--p1ai")
   if e != nil {
      panic(e)
   }
   s, e := idna.ToUnicode(p.Host)
   if e != nil {
      panic(e)
   }
   println(s == "природный-источник36.рф")
}

https://golang.org/pkg/net/url#Parse

An IDNA string consists of "labels" separated by dots ".". Each label may be encoded (if it starts with "xn--") or not (if it doesn't). Your string consists of two labels, https://xn---36-mddtcafmzdgfgpbxs0h7c and xn--p1ai. Only the second one is IDNA encoded.

Just process those parts of the URL which are IDNA encoded (i.e. the hostname). Anything else is just nonsensical and cannot work.
