Services

• The design concept of service is mainly to decouple controller and models. Service includes data validation, database addition, deletion, modification, query, etc. The business logic, data processing, etc. in the application can be referenced separately from the controller.

• The service module is always located in the services folder under the app application directory, and will be automatically imported when the application is imported. The namespace is {app name}. services
