`config.NewConfig()` with consul source will both read from consul and watch consul for changes. Hence, the `prefix` is used in these 2 cases: - read case: it is used to strip path based on the `KVPair` returned from consul `kv.List()` method - watch case: it is used as the `key` of watch query (`keyprefix` type) So for *watch case*, the `key` is leagal to be `/` for watching change on root. While for *read case*, because `KVPair.Key` is always stripped off the leading slash, so if user specified some `prefix` with leading slash, we should strip it also. An extream case would be: user want's to read & watch node in root dir. One would specify `prefix` as `/`, and it should work then. |
