通过集成对应语言的SDK Client,您可以在代码中直接操作Istio资源。本文以Java 11和SDK fabric8io/istio-client 6.0.0-RC1版本为例,介绍如何使用Java SDK操作Istio资源。

Dubbo 框架提供了 Triple 协议的多种语言实现，它们可以帮助你构建浏览器、gRPC 兼容的 HTTP API 接口：你只需要定义一个标准的 Protocol Buffer 格式的服务并实现业务逻辑，Dubbo 负责帮助生成语言相关的 Server Stub、Client Stub，并将整个调用流程无缝接入如路由、服务发现等 Dubbo 体系。Go、Java 等语言的 Triple...
