GO-Grpc微服务开发二 服务编写

# 服务编写 ## 1.定义proto文件 ```$xslt //示例为elc日志 syntax = "proto3"; //service name is kibana service Kibana { //service method is write rpc Write(WriteRequest) returns (WriteResponse) {} } //writer request struct message WriteRequest { string tag = 1; string info = 2; string level = 3; } //writer response struct message WriteResponse { int32 code = 1; string message = 2; map<string, string> data = 3; } ``` ## 2.将定义的proto编译为go文件 ```$xslt protoc --proto_path=.:. --micro_out=. --go_out=. kibana.proto ``` ## 3.编写服务 ```$xslt package main import ( proto "micro-srv/service/kibana/proto" "micro-srv/service/kibana/logics" "fmt" "micro-srv/common" "golang.org/x/net/context" ) //定义服务 type Kibana struct{} const ( //服务监听端口 SRV_PORT = 50061 //服务名称 SRV_NAME = "kibana" ) //服务中的方法必须要全都实现 func (k *Kibana) Write(ctx context.Context, req *proto.WriteRequest) (rsp *proto.WriteResponse, err error) { rsp.Code = 0 rsp.Message = "success" rsp.Data = map[string]string{"tag":req.Tag,"info":req.Info,"level":req.Level} err = logics.WriteLog(req.Tag, req.Info, req.Level) return rsp, err } func main() { //将服务注册到consul server, listener, err := common.Register(SRV_NAME, SRV_PORT) if err != nil { fmt.Println(err.Error()) } proto.RegisterKibanaServer(server, &Kibana{}) err = server.Serve(listener) if err != nil { fmt.Println(err.Error()) } } ``` # 微服务运行 （本地环境示例） ## 启动consul `consul agent -dev &` 面板地址：http://127.0.0.1:8500 ## 启动并注册服务 `cd kibana && go run main.go &`  可以看到我们服务以及运行起来了 接下来我们在consul面板看看  源码：[go-grpc-getway](https://github.com/juelite/micro-srv)
