| 1．本课题的研究目的和意义 |
| 随着学校面积的扩大，并且学生和老师人数的增多，因此携带的东西也会随着增加，同时学生和老师经常往来于不同的教学楼和场所，所以就会发生物品的丢失，而有些同学或老师无意中捡到该物品，但是，由于缺乏一个可以提供失主和拾主信息交流的平台，只能采用传统的失物招领方法，在校园贴出寻物启事和失物启事的方式，这种方法让信息扩散的速度比较慢，而且易给失主造成一定的经济损失。但是随着互联网技术的快速发展，智能手机已经成为学生和老师便捷的生活方式，所以为了能够高效的发布信息，并且缩短找回失物的时间，开发一个高效便捷的微信公众号校园失物招领平台显得尤为重要。 微信公众号校园失物招领平台支持游客通过微信登录，用户可以发布失物信息也可以发布拾物信息并且可以选择自己所在的学校进行发布。还能查看失物启事和拾物启事的详情信息，同时也可以搜索拾物信息。用户还可以浏览成功案例，系统公告，并且在个人中心编写系统留言。所有发布的信息都会保存下来，以便管理查看。 通过本系统的开发，将自己以前所学习到的知识结合实践，不仅是对这几年来对专业知识的总结，同时也是把所学到的知识进行收获和提升，这是对自身综合性的锻炼。 [1]李锦程.基于微信平台的医疗就诊系统设计与实现[D].哈尔滨:哈尔滨工业大学,2015.
