Etwa `/users/me`, um Daten über den aktuellen Benutzer zu erhalten.

Und Sie haben auch einen Pfad `/users/{user_id}`, um Daten über einen spezifischen Benutzer zu erhalten, mittels einer Benutzer-ID.

Weil *Pfadoperationen* in ihrer Reihenfolge ausgewertet werden, müssen Sie sicherstellen, dass der Pfad `/users/me` vor `/users/{user_id}` deklariert wurde:

```Python hl_lines="6  11"

	users := set.NewStringSet()
	for _, kv := range kvs {
		user := extractPathPrefixAndSuffix(string(kv.Key), prefix, path.Base(string(kv.Key)))
		users.Add(user)
	}
	return users
}

// Extract path string by stripping off the `prefix` value and the suffix,
// value, usually in the following form.
//
//	s := "config/iam/users/foo/config.json"
//	prefix := "config/iam/users/"
