一、前言

在当今数字化社会，人们的生活与互联网紧密相连。特别是在校园环境中，学生们的生活方式已经深深地受到了互联网的影响。失物招领问题在校园中是一个常见的问题，影响着广大的师生的日常生活和学习。因此，开发一款基于互联网的校园失物招领平台，如微信小程序或安卓APP，已经成为了一个迫切的需求。

尽管目前已经存在一些失物招领的解决方案，如校园公告板、失物招领微信群等，但它们存在着一些问题。首先，这些平台的信息传播范围有限，往往只能在一定区域内进行传播，无法覆盖整个校园。其次，这些平台的信息更新速度慢，往往需要一定的时间才能更新，无法满足快速失物招领的需求。因此，我们需要一种更便捷的解决方案来解决这些问题。

本课题的研究目的是开发一款基于互联网的校园失物招领平台，以解决现有解决方案的问题。具体来说，我们将实现以下功能：
用户可以通过微信小程序或安卓APP上传失物信息，包括物品名称、描述、丢失地点等；
用户可以通过微信小程序或安卓APP查询失物信息，包括已发布的失物信息、失物招领状态等。

本课题的研究意义在于提供一种更便捷的校园失物招领解决方案。通过开发基于互联网的校园失物招领平台，我们可以帮助学生和教职工更快速地找到丢失的物品，提高他们的学习和工作效率。同时，我们也可以通过平台的数据分析功能，了解校园内失物招领的现状和问题，为学校的管理和改进提供参考。因此，本课题的研究成果具有重要的实用价值和社会意义。
