-* 启用h2\(Http2 + TLS\)进行通信
- 服务端在配置服务监听地址时，可以通过在地址后面追加`?sslEnabled=true`开启TLS通信，具体介绍见[使用TLS通信](../../security/tls.md)章节。然后再追加`&protocol=http2`启用h2通信。示例如下：
+* Enable h2\(Http2 + TLS\) for communication
+ When configuring the service listening address, the server can enable TLS communication by appending `?sslEnabled=true` to the address. For details, see the section [Using TLS Communication] (../../security/tls.md). Then add `&protocol=http2` to enable h2 communication. An example is as follows:
