微服务里得HelloWorld

greeter.proto

protoc greeter.proto

syntax = "proto3";

//服务
service Greeter {
	rpc Hello(HelloRequest) returns (HelloResponse) {}
}

//输入参数
message HelloRequest {
	string name = 1;
}

//输出参数
message HelloResponse {
	string greeting = 2;
}

server.go

package main

import (
	"context"
	"log"
	"time"

	proto "github.com/micro/examples/helloworld/proto"
	"github.com/micro/go-micro"
	"github.com/micro/go-micro/registry/consul"
	"github.com/micro/go-micro/registry"
)

type Greeter struct{}

//平时写业务就是实现这里
func (g *Greeter) Hello(ctx context.Context, req *proto.HelloRequest, rsp *proto.HelloResponse) error {
	rsp.Greeting = "Hello " + req.Name
	return nil
}

func main() {
	//指定服务发现的网络位置(也可以在命令行指定)
	reg := consul.NewRegistry(func(op *registry.Options) {
		op.Addrs = []string{
			"wuxiangege.com:8500",//公网
			"127.0.0.1:8500",//内网
		}
	})

	//初始化
	service := micro.NewService(
		micro.Registry(reg), //指定服务发现的网络位置
		micro.Name("greeter"), //微服务名字
		micro.RegisterTTL(time.Second*30), //微服务信息过期时间
		micro.RegisterInterval(time.Second*20),//再次注册的时间间隔
	)

	service.Init()

	//关联
	proto.RegisterGreeterHandler(service.Server(), new(Greeter))

	if err := service.Run(); err != nil {
		log.Fatal(err)
	}
}
