Function urlString

urlfetch/urlfetch.go:111–118

urlString returns a valid string given a URL. This function is necessary because the String method of URL doesn't correctly handle URLs with non-empty Opaque values. See http://code.google.com/p/go/issues/detail?id=4860.

(u *url.URL)

// the String method of URL doesn't correctly handle URLs with non-empty Opaque values.
// See http://code.google.com/p/go/issues/detail?id=4860.
func urlString(u *url.URL) string {
	if u.Opaque == "" || strings.HasPrefix(u.Opaque, "//") {
		return u.String()
	}
	aux := *u
	aux.Opaque = "//" + aux.Host + aux.Opaque
	return aux.String()
}
