安装（前提是本地已安装protobuf和protof的go扩展）

go get github.com/micro/micro

go get github.com/micro/go-micro

go get github.com/micro/protoc-gen-micro

go get github.com/micro/go-plugins/registry/consul

支持consul需要单独安装这个包

go get github.com/micro/go-plugins/registry/consul

micro生成新项目

micro new --gopath=false --type=srv micpro

进入到 proto文件的同级目录，然后执行以下命令生成go文件

protoc --micro_out=. --go_out=. *.proto

package main

import (
	"github.com/micro/go-micro"
	"github.com/micro/go-micro/util/log"
	"github.com/micro/go-plugins/registry/consul"
	"micpro/handler"
	micpro "micpro/proto/micpro"
)

func main() {

	consulRegis := consul.NewRegistry()

	// New Service
	service := micro.NewService(
		micro.Name("go.micro.srv.micpro"),
		micro.Version("latest"),
		micro.Registry(consulRegis),
		micro.Address("127.0.0.1:10345"),
	)

	// Initialise service
	service.Init()

	// Register Handler
	micpro.RegisterMicproHandler(service.Server(), new(handler.Micpro))

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

将micro框架proto目录下的文件拷贝到gin目录下，然后在main.go中使用consul

package main

import (
	context2 "context"
	"fmt"
	micpro "gintemp/proto/micpro"
	"github.com/gin-gonic/gin"
	"github.com/micro/go-micro"
	"github.com/micro/go-micro/client"
	"github.com/micro/go-plugins/registry/consul"
	"time"
)

func microCall(context *gin.Context){

	reg := consul.NewRegistry()
	service := micro.NewService(micro.Registry(reg))
	micServ := micpro.NewMicproService("go.micro.srv.micpro",service.Client())
	res,err := micServ.Call(context2.TODO(),&micpro.Request{Name:"mayuan"},func(o *client.CallOptions) {
		o.RequestTimeout = time.Second * 30
		o.DialTimeout = time.Second * 30
	})
	if err != nil{
		fmt.Println(err)
	}
	context.Writer.WriteString(res.Msg)
}


func main() {
	route := gin.Default()
	route.GET("/", microCall)
	route.Run(":8080")
}
