## 一.环境说明 ##

1.系统: window10  
2.micro 版本

C:\Users\Administrator>micro --version
    micro version 1.10.0

3.go版本

C:\Users\Administrator>go version
    go version go1.12.9 windows/amd64

4.protoc版本

C:\Users\Administrator>protoc --version
    libprotoc 3.9.2

--------------------

## 二.安装protoc,consul,micro,protoc-gen-go,protoc-gen-grpc-gateway,protoc-gen-micro,protoc-gen-swagger,这些工具就不介绍了，请直接参考官网[micro][] ##

![micro][micro 1]  
安装完成之后就进行编码阶段了

## 三.编码 ##

生成go-micro的protoc文件

syntax = "proto3";
    
    package go.micro.srv.greeter;
    
    service Say {
    	rpc Hello(Request) returns (Response) {}
    }
    
    message Request {
    	string name = 1;
    }
    
    message Response {
    	string msg = 1;
    }

main函数

package main
    
    import (
    "log"
    "time"
    
    hello "grpcdemo/grpc/server/srv/proto"
    "github.com/micro/go-micro"
    "github.com/micro/go-micro/service/grpc"
    "context"
    )
    
    type Say struct{}
    
    func (s *Say) Hello(ctx context.Context, req *hello.Request, rsp *hello.Response) error {
    	log.Print("Received Say.Hello request")
    	rsp.Msg = "Hello " + req.Name
    	return nil
    }
    
    func main() {
    	service := grpc.NewService(
    		micro.Name("go.micro.srv.demo"),
    		micro.RegisterTTL(time.Second*30),
    		micro.RegisterInterval(time.Second*10),
    	)
    
    	// optionally setup command line usage
    	service.Init()
    
    	// Register Handlers
    	hello.RegisterSayHandler(service.Server(), new(Say))
    
    	// Run server
    	if err := service.Run(); err != nil {
    		log.Fatal(err)
    	}
    }

生成go-micro文件命令

protoc -IH:\downloads\protoc-3.9.2-win64\include -I. -ID:\workspace\src -ID:\workspace\src\github.com\grpc-ecosystem\grpc-gateway\third_party\googleapis --go_out=plugins=grpc:. --micro_out=.  hello.proto

生成之后，proto文件目录下多了两个文件  
![11][]

gateway相关  
proto文件

syntax = "proto3";
    
    package proto;
    
    import "google/api/annotations.proto";
    
    service Say {
        rpc Hello(Request) returns (Response) {
            option (google.api.http) = {
    			post: "/greeter/hello"
    			body: "*"
    		};
        }
    }
    
    message Request {
        string name = 1;
    }
    
    message Response {
        string msg = 1;
    }

main.go

package main
    
    import (
    	"flag"
    	"net/http"
    
    	"context"
    	"github.com/golang/glog"
    	"github.com/grpc-ecosystem/grpc-gateway/runtime"
    	"google.golang.org/grpc"
    
    	hello "grpcdemo/grpc/gateway/proto"
    )
    var (
    	// the go.micro.srv.greeter address
    	endpoint = flag.String("endpoint", "localhost:9090", "go.micro.srv.greeter address")
    )
    
    func run() error {
    	ctx := context.Background()
    	ctx, cancel := context.WithCancel(ctx)
    	defer cancel()
    
    	mux := runtime.NewServeMux()
    	opts := []grpc.DialOption{grpc.WithInsecure()}
    
    	err := hello.RegisterSayHandlerFromEndpoint(ctx, mux, *endpoint, opts)
    	if err != nil {
    		return err
    	}
    
    	return http.ListenAndServe(":8080", mux)
    }
    
    func main() {
     flag.Parse()
    
    	defer glog.Flush()
    
    	if err := run(); err != nil {
    		glog.Fatal(err)
    	}
    }

生成gw文件  
![go][]

D:\workspace\src\grpcdemo\grpc\gateway\proto>protoc -IH:\downloads\protoc-3.9.2-win64\include -I. -ID:\workspace\src -ID:\workspace\src\github.com\grpc-ecosystem\grpc-gateway\third_party\googleapis --go_out=plugins=grpc:. --grpc-gateway_out=logtostderr=true:. hello.proto

最后生成的文件如下图  
![1212][]

## 四.启动测试 ##

1.启动consul作为注册中心

consul agent -dev

验证consul,访问地址http://localhost:8500/ui/dc1/services  
![12123][]

启动服务  
server

D:\workspace\src\grpcdemo\grpc\server\srv>go run main.go --registry consul --server_address localhost:9090
    2019/10/01 19:35:50 Server [grpc] Listening on 127.0.0.1:9090
    2019/10/01 19:35:50 Broker [http] Connected to [::]:62483
    2019/10/01 19:35:50 Registering node: go.micro.srv.demo-2e486455-1176-44b4-b4fc-fbd68c3fbd57

启动网关服务
