示例1: Hello

func (s *Say) Hello(ctx context.Context, req *api.Request, rsp *api.Response) error {
	log.Info("Received Say.Hello API request")

	name, ok := req.Get["name"]
	if !ok || len(name.Values) == 0 {
		return errors.BadRequest("go.micro.api.greeter", "Name cannot be blank")
	}

	request := client.NewRequest("go.micro.srv.greeter", "Say.Hello", &hello.Request{
		Name: strings.Join(name.Values, " "),
