葡萄 - 在V2内安装V1

Question

我使用Grape创建API，我遇到了问题：如何在V2中安装V1

/api/v1/users.rb

module API
  module V1
    class Users < Grape::API
      resource :users do
        desc "Timeline" do
        end
        get :time_line do
         {status: true, version: 'v1'}
        end

        desc "Timeline" do
        end
        get :profile do
         {status: true, profile: {email: "julian@vinova.sg"}, version: 'v1'}
        end
      end
    end
 end
end

/api/v1/base.rb

module API
  module V1
    class Base < Grape::API
        prefix 'api'
        format :json
        version 'v1', using: :path


        mount API::V1::Users

        add_swagger_documentation \
          api_version: 'v1'
    end
  end
end

/api/v2/users.rb

module API
  module V2
    class Users < Grape::API
      resource :users do
        desc "Timeline" do
       end
       params do
        use :pagination
       end
       get :time_line do
        {status: true, version: 'v2'}
       end
      end
    end
  end
end

/api/v2/base.rb

module API
  module V2
    class Base < Grape::API
        prefix 'api'
        format :json
        version 'v2',  using: :path


        mount API::V2::Users

        add_swagger_documentation \
          api_version: 'v2'
     end
  end
end

/api/base.rb

module API
  class Base < Grape::API
    mount ::API::V1::Base
    mount ::API::V2::Base
  end
end

我想：配置文件（/ api / v2 / users / profile）也可以在V2中实现，而不必重复代码。现在，有什么建议吗？ 感谢
