urls.go

func main() {
    // let's parse some youarells
    url1, _ := url.Parse("http://www.example.com")
    url2, _ := url.Parse("www.example.com")

    // oops, this the second one needs a scheme, let's set one:
    url2.Scheme = "http"

    // perfect - now my urls are the same
    fmt.Println(url1.String()) // => http://www.example.com
    fmt.Println(url2.String()) // => http://www.example.com

    // but wait...
    fmt.Println(url1.Host) // => www.example.com
    fmt.Println(url2.Host) // => ""

    // hmm - what's the path?
    fmt.Println(url1.Path) // => ""
    fmt.Println(url2.Path) // => www.example.com, doesn't look like a path...

    // what happens if we parse it again...
    url2a, _ := url.Parse(url2.String())
    fmt.Println(url1.Host)  // => www.example.com
    fmt.Println(url2a.Host) // => www.example.com
