How do I parse URLs in the format of /id/123 not ?foo=bar

Question

I'm trying to parse an URL like:

http://example.com/id/123

I've read through the net/url docs but it seems like it only parses strings like

http://example.com/blah?id=123

How can I parse the ID so I end up with the value of the id in the first example?

This is not one of my own routes but a http string returned from an openid request.

You can try using regular expression as follow:

import "regexp"

re, _ := regexp.Compile("/id/(.*)")
values := re.FindStringSubmatch(path)
if len(values) > 0 {
    fmt.Println("ID : ", values[1])
}
