go-micro 客户端访问服务端 报错 500 访问不到

报错 {"id":"go.micro.client","code":500,"detail":"service hello.service: not found","status":"Internal Server Error"} 是这样最近在学习微服务 看了好多课程踩了好多的坑 版本兼容性搞完了结果还是出现了问题 希望哪位路过的大佬帮忙瞅瞅 看一下啥问题了 服务端(可以启动) ``` package main import ( pb "GoTest/newmicro/proto" "context" "fmt" "github.com/micro/go-micro" ) type Cap struct { } func (c *Cap) SayHello(ctx context.Context, Requ *pb.SayRequest, Resp *pb.SayResponse) error { Resp.Msg = "太阳当空照" + Requ.Message return nil } func main() { service := micro.NewService( micro.Name("hello.service"), ) service.Init() //注册服务 pb.RegisterCapHandler(service.Server(), new(Cap)) if err := service.Run(); err != nil { fmt.Println() } } ``` 客户端(报错500) ``` package main import ( pb "GoTest/newmicro/proto" "context" "fmt" "github.com/micro/go-micro" "github.com/micro/go-micro/registry" "github.com/micro/go-micro/registry/mdns" ) func main() { reg := mdns.NewRegistry(func(op *registry.Options) { op.Addrs = []string{ "127.0.0.1:8500", } }) service := micro.NewService( micro.Name("hello.client"), ) service.Init(micro.Registry(reg)) capPb := pb.NewCapService("hello.service", service.Client()) res, err := capPb.SayHello(context.TODO(), &pb.SayRequest{Message: "哈哈哈哈哈哈"}) if err != nil { fmt.Println("报错", err) return } fmt.Println(res.Msg) } ``` go mod ``` module GoTest/newmicro go 1.14 require ( github.com/golang/protobuf v1.4.3 github.com/micro/go-micro v1.18.0 github.com/micro/go-micro/v2 v2.9.1 google.golang.org/protobuf v1.25.0 ) replace google.golang.org/grpc => google.golang.org/grpc v1.26.0 ```
