篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了手撸一个在线学习在线教育小程序相关的知识，希望对你有一定的参考价值。
最近有小伙伴找小孟开发了一个在线教育的小程序项目。
一，小程序介绍
微信小程序，它的简称是小程序，其英文名称叫做Mini Program，是一种不需要在手机应用商店里面下载就可以在微信平台当中立即使用的H5轻应用。用户只需要通过微信扫描二维码或者搜索小程序就可以体验小程序功能。
小程序开发技术的最主要目的就是通过最简洁的方式让开发者基于微信平台开发具有原生应用软件的服务。小程序框架系统分为视图层和逻辑层，其中视图层提供自身的视图层独有的描述语言WXML和WXSS，逻辑层框架则基于javascript。小程序框架的视图层（View）与逻辑层（APP Service）之间提供了数据传输和事件系统，使得数据和视图保持同步。方便让开发者聚集在数据和逻辑当中。
二，微信开发者工具介绍
微信开发者工作是微信官方提供的针对微信小程序的开发工具，集中了开发，调试，预览，上传等功能。微信团队发布了微信小程序开发者工具、微信小程序开发文档和微信小程序设计指南，全新的开发者工具，集成了开发调试、代码编辑及程序发布等功能，帮助开发者简单和高效地开发微信小程序。启动工具时，开发者需要使用已在后台绑定成功的微信号扫描二维码登录，后续所有的操作都会基于这个微信的帐号，程序调试主要有三大功能区：模拟器、调试工具和小程序操作区：模拟器模拟微信小程序在客户端真实的逻辑表现，对于绝大部分的 API 均能够在模拟器上呈现出正确的状态。调试工具分为 6 大功能模块：Wxml、Console、Sources、Network、Appdata、Storage以及WxmlPannel。微信小程序操作区帮助开发者模拟一些客户端的环境操作。例如当用户从微信小程序中回到聊天窗口，会触发一个微信小程序被设置为后台的api。
三，系统技术栈和功能介绍
系统的后端采用的SpringBoot进行开发，数据库采用mysql，移动端采用的小程序，Web端前端采用的Vue进行开发。
系统的功能介绍如下所示：
四，系统演示
系统的视频演示如下所示：
