Introducción al proyecto
Este proyecto es un sistema de gestión de front-end y back-end, que incluye dos funciones de administrador y usuario ordinario;
la función de administrador incluye las siguientes funciones:
inicio de sesión del administrador, gestión de usuarios, gestión de tipo de producto, gestión de productos, gestión de información de pedidos, mensaje de usuario gestión, gestión de la información, etc. Características.
El rol de usuario incluye las siguientes funciones:
página de inicio de usuario, inicio de sesión de usuario, recomendación de productos, información de información, panel de mensajes, visualización de productos, envío de pedidos, visualización de información de pedidos, gestión de datos personales y otras funciones.
PD: el módulo de recomendaciones utiliza el algoritmo de recomendación de filtrado colaborativo y el módulo de pedidos utiliza la API de mapas de Baidu. Este centro comercial se puede modificar a cualquier centro comercial, no solo a un centro comercial deportivo.
