安装 趟坑

装这个版本

go get -u -v github.com/micro/go-micro@v1.8.0

高级版本已经没有 consul

启动服务发现的例子

package main

    "github.com/micro/go-micro/registry"
    "github.com/micro/go-micro/registry/consul"
    "github.com/micro/go-micro/web"
)

func main()  {
    consulReg := consul.NewRegistry(
          registry.Addrs("192.168.3.9:8500"),
        )
    ginRoute:=gin.Default()
    ginRoute.Handle("GET","/user", func(context *gin.Context) {
        context.String(200,"user api")
    })


    server := web.NewService(
        web.Name("asdasd"),
        web.Address(":8001"),
        web.Handler(ginRoute),
        web.Registry(consulReg),
        )
    server.Run()

}

执行 protoc --go_out=./ --micro_out=./ *.proto 报错​

  • 'protoc-gen-micro' 不是内部或外部命令，也不是可运行的程序
# 安装 protoc-gen-go
go get google.golang.org/protobuf/cmd/protoc-gen-go
go install google.golang.org/protobuf/cmd/protoc-gen-go

# 安装 protoc-gen-micro 
go get github.com/micro/micro/v2/cmd/protoc-gen-micro
go install github.com/micro/micro/v2/cmd/protoc-gen-micro@latest

# V3版本的
go install github.com/asim/go-micro/cmd/protoc-gen-micro/v3@latest

etcd 与 grpc 不测试问题的​

解决方案： 在go.mod中将grpc的版本修改为v1.26.0

下面语句添加上去的,直接修改版本号,会遇到另外的坑

replace (
    google.golang.org/grpc => google.golang.org/grpc v1.27.1
)

micro api --handler=rpc

调用 rpc 方法 micro call service Cap.SayHello
