[hhniao]

	"go-micro.dev/v4"
	grpcc "github.com/go-micro/plugins/v4/client/grpc"
	grpcs "github.com/go-micro/plugins/v4/server/grpc"
)
func main() {
	// Create service
	srv := micro.NewService(
		micro.Server(grpcs.NewServer()),
		micro.Client(grpcc.NewClient()),
	)
}

when delete micro.Server(grpcs.NewServer())

1, example/gateway
the gateway code it is work, otherwise will show me
{"error":"malformed header: missing HTTP content-type","code":2,"message":"malformed header: missing HTTP content-type"}
or
{"msg":"Hello john"}

2, example/http/rpccli, it is work.

2, example/http/rpccli, it is not work.
