摘  要

进入21世纪后，全球也进入了信息化时代.随着网络时代来临，作为新兴交流媒体之一的博客，也成为目前应用最为广泛的网络交流平台之一。博客作为目前应用最为广泛的社交媒体，它相较于其他社交媒体具有操作简单，界面美观等优点，在广大用户中应用广泛.相较于如E-Mail，论坛，网站等传统媒体，缺乏个人个性，缺乏自由，延时的缺点，博客更能适用于现代用户的需求.传统的博客系统已经不能够满足用户的需求，而目前大部分博客系统的开发专注于企业或社会其它机构，而对于普通的用户的需求关注较少.因此，创建适用于个人沟通与交流，功能完善的博客系统是十必要的。

该博客系统是一款分享型博客，注重个人的学习心得，生活等方面的记录.后台基于Python中的Flask框架开发，还涉及爬虫，数据库使用的是轻型的SQLite，同时，前端页面的实现涉及HTML，JavaScript等。系统角色分为游客，用户，管理员，游客只能进行查看操作，用户可以发表并管理博客和评论，喜欢他人的博客，用户还可以在个人中心编辑个人信息等操作，管理员可以对所有博客和评论等进行增删改查操作。博客编辑与查看使用的是富文本，涉及MarkDown语言。
