go-micro+consul+gin

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")
}
