-Some of the configuration fields supported in Upstream are not supported in weighted_upstreams.upstream. These fields are `service_name`, `discovery_type`, `checks`, `retries`, `retry_timeout`, `desc`, `scheme`, `labels`, `create_time`, and `update_time`.
+Some of the configuration fields supported in Upstream are not supported in weighted_upstreams.upstream. These fields are `service_name`, `discovery_type`, `checks`, `retries`, `retry_timeout`, `desc`, `labels`, `create_time`, and `update_time`.
 
 As a workaround, you can create an Upstream object and configure it in `weighted_upstreams.upstream_id` to achieve these functionalities.

-目前 `weighted_upstreams.upstream` 的配置不支持 `service_name`、`discovery_type`、`checks`、`retries`、`retry_timeout`、`desc`、`scheme`、`labels`、`create_time` 和 `update_time` 等字段。如果你需要使用这些字段，可以在创建上游对象时指定这些字段，然后在该插件中配置 `weighted_upstreams.upstream_id` 属性即可。
