摘要
很多的高校为了方便学生对图书的查看和订阅,都推出了图书馆管理系统,但是大部分的图书馆管理系统是基于互联网部署使用的,对环境的依赖性比较大.随着信息技术的不断发展,我国已经进入了微服务时代,通过移动APP和微信公众号向用户提供信息服务已经成为了主流的趋势,鉴于APP需要下载安装,占用内存比较大。
本微信图书借阅平台是一个完整的B/S架构的实现，在服务器端通过Nginx监听用户请求并分发请求给StrongLoop进程管理器，StrongLoop创建多个slave进程维护Node.js实例来处理用户请求，Node.js作为中间层可以构建在任何其他语言的后端之上，通过基于RESTful规则设计的接口可以建立Node.js中间层与其他后端语言的数据通信。数据库采用MySQL、通过Jade模板引擎实现服务端HTML预渲染、在客户端通过微信内置的Blink内核的WebView作为与用户交互的入口、UI效果展示采Bootstrapcss界面库快速制作移动端友好的响应式界面。

Abstract
In order to facilitate students' view and subscribe to books, many universities have launched library management systems, but most library management systems are based on the Internet deployment and are relatively dependent on the environment. With the continuous development of information technology, China has entered the era of micro-service. It has become a mainstream trend to provide information services to users through mobile APP and WeChat public account. In view of the need for APP to download and install, it occupies a relatively large memory.
This WeChat book lending platform is the implementation of a complete B / S architecture that listens for user requests on the server-side through Nginx and distributes requests to the StrongLoop Process Manager, StrongLoop creates multiple instances of slave process maintenance Node.js to process user requests, Node.js as the middle layer can be built above the back end of any other language, and the Node.js middle layer and other back-end languages can be established through an interface designed based on RESTful rules.The database uses MySQL, service HTML pre-rendering through Jade template engine, WebView through the wechat built-in Blink kernel on the client as the entrance for interaction with users, and UI effect display Bootstrapcss interface library quickly makes a mobile end-friendly responsive interface.
Key words: WeChat; public account; book management; borrowing; Node.js
