    "net/http"

    "github.com/crochee/rest"
)

type IClient interface {
	Area() AreaSrv
}

func NewGateway() IClient {
	return &baseClient{reqest.NewHandler().Endpoint("http://localhost:80")}
}

type baseClient struct {
	rest.Handler
}

func (c baseClient) Area() AreaSrv {
	return areaSrv{c.Resource("areas")}
}

type AreaSrv interface {
	Get(ctx context.Context, id string) (*Areas, error)
}

type areaSrv struct {
	rest.Handler
}

func (a areaSrv) Get(ctx context.Context, id string) (*Areas, error) {
	var result Areas
	if err := a.To().
		Get().
		Prefix("v2").
		Name(id).
		Do(ctx, &result); err != nil {
		return nil, err
	}
	return &result, nil
}

type Areas struct {
	List     []string `json:"list"`
	PageNum  int      `json:"page_num"`
	PageSize int      `json:"page_size"`
	Total    int      `json:"total"`
}

func main() {
	result, err := NewGateway().Area().Get(context.Background(), "12")
	if err != nil {
		log.Fatal(err)
	}
	log.Println(result)
}
