Mở template.yaml trong thư mục fcj-book-shop.
Thêm đoạn mã sau vào cuối tệp để tạo REST API và phương thức GET.
Đầu tiên, chúng ta sẽ tạo tham số stage.
stage:
Type: String

Tiếp theo, thêm các đoạn mã sau để tạo phương thức BookApiGet, triển khai BookApiDeployment, giai đoạn BookApiStage và quyền BookApiGetInvokePermission.
