type JwtAuth struct {
	auth.Auth
}

func (a JwtAuth) Inspect(token string) (*auth.Account, error) {
	conf := config.Config()
	claims, err := Jwt{}.Validation(token, conf.JWT.Secret, false)
	if err != nil {
		return nil, err
	}

	id, _ := claims.GetSubject()
	return &auth.Account{
		ID: id,
	}, nil
}

func NewAuthWrapper(service micro.Service) server.HandlerWrapper {
	return func(h server.HandlerFunc) server.HandlerFunc {
		return func(ctx context.Context, req server.Request, rsp interface{}) error {
			... the rest code
			a := service.Options().Auth
			acc, err := a.Inspect(token)
                        ... the rest code
