摘 要
随着应用技术的发展以及电子商务平台的崛起，利用线上平台实现的二手交易为传统的二手交易市场注入了新的生机，大学校园内的新生和应届毕业生的相互交替产生了巨大的二手交易空间，同时考虑到环保和资源再利用，大学校园的书籍二手交易需求量不断增加，结合网购的便捷性很多大学生利用网购交易平台实现在线的学习用品及生活用品的购买，帮助节约生活开支的同时也让闲置的物品得到了二次利用。目前人们所熟知的二手交易平台如转转、闲鱼等，作为综合型二手交易平台涵盖了大量的商品，但是无法满足很多大学生对于专业书籍的选择以及学习资料的获取，很多大学生还在通过他人介绍来实现二手书籍的交易，结合而当前大学生二手交易的现状，利用微信小程序应用的便捷性开发设计一款针对大学校园环境内的二手教材及书籍拍卖系统，利用该系统实现在线的书籍教材拍卖，通过竞拍和加价的方式来实现书籍的交易，满足学生书籍需求的同时也实现了资源的再利用。
此次大学校园二手教材与书籍拍卖系统平台的开发设计主要借助微信小程序端来实现，微信小程序依托微信应用平台来实现使用，因此用户不需要额外安装应用且能够实现随时随地的应用和分享，主要的功能模块包括了书籍信息查询、竞拍信息管理以及书籍在线拍卖等内容，结合用户端的需求对于书籍信息的管理按照类别进行划分，同时考虑竞拍的公平公正性需要设定对应的竞拍结束时间、竞拍实时价格，对于竞拍入围的用户开通对应的在线支付窗口，通过以上功能模块的运行来实现二手教材及书籍拍卖系统平台的运行。
