+The control API server does not support parameter matching by default, if you want to enable parameter matching in plugin's control API
+you can add `router: 'radixtree_uri_with_parameter'` to the `control` section.
+
 Note that the control API server should not be configured to listen to the public traffic!

+插件的 control API 在默认情况下不支持参数匹配，如果想启用参数匹配功能可以在 control 部分添加 `router: 'radixtree_uri_with_parameter'`

 注意: control API server 不应该被配置成监听公网地址。
