go-micro grpc gateway windowns10使用記錄

一.環境說明

1.系統: 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.安裝protoc,consul,micro,protoc-gen-go,protoc-gen-grpc-gateway,protoc-gen-micro,protoc-gen-swagger,這些工具就不介紹了，請直接參考官網micro

安裝完成之後就進行編碼階段了

三.編碼

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函數

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

生成之後，proto文件目錄下多了兩個文件

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

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

最後生成的文件如下圖

四.啓動測試

1.啓動consul作爲註冊中心

consul agent -dev

驗證consul,訪問地址http://localhost:8500/ui/dc1/services

啓動服務
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

啓動網關服務

驗證
