| <p>grpc_cli 工具是 gRPC 生态用于调试服务的工具，在 server 开启<a href="https://github.com/grpc/grpc/blob/master/doc/server-reflection.md">反射服务</a>的前提下，可以获取到服务的 proto 文件、服务名、方法名、参数列表，以及发起 gRPC 调用。</p> |
| <p>Triple 协议兼容 gRPC 生态，并默认开启 gRPC 反射服务，因此可以直接使用 grpc_cli 调试 triple 服务。</p> |

| <h2 id="1-框架配置">1. 框架配置</h2> |
| <p>Dubbo-go 框架需要依赖配置进行启动。配置中包含了开发者希望使用框架的各种能力。</p> |
| <h3 id="配置格式">配置格式</h3> |
| <p>yaml</p> |
| <h3 id="配置路径">配置路径</h3> |
| <p>默认从 <code>../conf/dubbogo.yaml </code> 加载框架配置</p> |
| <p>可通过指定环境变量：DUBBO_GO_CONFIG_PATH=$(your_config_path)/dubbogo.yaml 来修改配置文件路径。</p> |
| <h3 id="配置根结构">配置根结构</h3> |
| <p>位于 <a href="https://github.com/apache/dubbo-go/blob/e00cf8d6fb2be3cd9c6e42cc3d6efa54e10229d3/config/root_config.go#L50">dubbo.apache.org/dubbo-go/v3/config/root_config.go: RootConfig</a></p> |
| <p>框架加载时，任何形式的配置都会被解析成 RootConfig，在 RootConfig.Init 方法中加载。</p> |
| <h2 id="2-配置api">2. 配置API</h2> |
| <p>开发者可以使用 API 的形式构建配置，从而启动框架。该方法较适合 dubbo-go 作为第三方组件引入的情况。</p> |
| <h2 id="3-配置中心">3. 配置中心</h2> |
| <p>开发者可以将配置放置在配置中心，从而便于配置的管理和修改。</p></description></item></channel></rss> |
