基于 html 和 mongodb 的电子产品购物网站 Electronic Product Shopping Website Based on HTML and Mongodb 摘要大部分网站都还停留在使用传统的 html+css 上，通过对其他相似课题文献的调查研究，本系统更多的集中在如何使购物网站能够在保证个人信息安全的同时提高系统运行效率，也要给用户良好的体验感。因此本系统决定使用 nodejs 搭建运行环境，express 框架作为系统本系统开发框架，利用 ajax 异步操作来提高用户体验和数据交互速度，使用了当下较为流行的 nosql 数据库——MongoDB 数据库：具有更高的插入速度、能处理大规模的单表、可以快速、安全以及自动的实现数据转移、查询速度更快、非结构化的爆发增长等。大量使用 session 缓存代替传统 cookie 缓存、自定义加密方法对用户密码加密之后再保存到数据库使用户数据的安全性得到极大地提高。遵循 MVC 设计模式，高内聚低耦合，系统便于使用和管理、优化。关键词： nodejs MongoDB MVC express ejsAbstract Most websites still use traditional HTML + CSS. Through the investigation and research of other similar subjects, this system focuses more on how to make the shopping website to ensure the security of personal information and improve the efficiency of the system, but also to give users a good sense of experience.Therefore, the system decided to use nodejs to build the running environment. As the development framework of the system, express framework used Ajax asynchronous operation to improve the user experience and data interaction speed. It used the current popular NoSQL database mongodb database, which has higher insertion speed, can handle large-scale single table, and can quickly, safely and automatically realize data Transfer, query faster, unstructured explosive growth and so on. Session cache is widely used instead of traditional cookie cache, and user-defined encryption method is used to encrypt the user's password before saving it to the database, which greatly improves the sec...
