Chapter 4, part 17, Server

[davidka79]

Hello
I am trying to study your course, but I can not pass a 17th path of the Lesson
First protoc format and keys was changed and I was needed to read a documentation for update keys and set the full path for package.

For now I am trying to follow a simple add listener and getting error
server.go

package main

import (
	"fmt"
	"github.com/davidka79/go-grp-study/greet/greetpb"
	"google.golang.org/grpc"
	"log"
	"net"
)

type server struct {}


func main() {
	fmt.Println("Hello World")

	lis, err := net.Listen("tcp", "0.0.0.0:50051")
	if err != nil {
		log.Fatalf("Failed %v", err)
	}
	s := grpc.NewServer()
	greetpb.RegisterGteetServiceServer(s, &server{})

	if err := s.Serve(lis); err != nil {
		log.Fatalf("Failed to serve %v", err)
	}
}

here at greetpb.RegisterGteetServiceServer(s, &server{}) the error that *"Cannot use '&server{}' (type server) as the type GteetServiceServer Type does not implement 'GteetServiceServer' as some methods are missing: mustEmbedUnimplementedGteetServiceServer()"

I tried many ways but still not succeed, probably need to update code, but I do not know what to do

as far as greetpb.UnimplementedGteetServiceServer it is a type, this way is working

var server greetpb.UnimplementedGteetServiceServer

Update the struct as follows:

  type server struct {
   greetpb.UnimplementedGreetServiceServer
}
