最近在网上看到别人做的爬取微信聊天记录并分析聊天内容,GitHub上试着运行了一下,这好东西肯定要分享出来给各位,总结一下几年的微信聊天内容?,废话不多说,下面一步步来。先展示一下,我和我对象的聊天内容分析:
源代码和出处:GitHub - LC044/WeChatMsg: 提取微信聊天记录,将其导出成HTML、Word、CSV文档永久保存,对聊天记录进行分析生成年度聊天报告
大家记得给作者点点star,督促作者开发更优的信息抓取功能。
一、微信聊天记录爬取
下载微信聊天记录爬取程序:(软件安全正常,直接无视安全问题?)
https://github.com/LC044/WeChatMsg/releases/download/v1.0.6/MemoTrace-1.0.6.exe
电脑需要登录微信,如果电脑微信聊天记录不齐全,可以通过手机进行微信聊天记录迁移。
安卓: 手机微信->我->设置->聊天->聊天记录迁移与备份->迁移-> 迁移到电脑微信(迁移完成后重启微信)iOS: 手机微信->我->设置->通用->聊天记录迁移与备份->迁移-> 迁移到电脑微信(迁移完成后重启微信)打开软件,随后点击获取信息,获取手机号、微信昵称、wxid等内容,之后点击开始启动就行。
若出现wxid或微信路径无法获取问题,查看解决办法("留痕"使用教程 (lc044.love)),一般都是没问题的。
选择 “数据 --> 批量导出”,选择你想要导出的联系人信息。导出格式选择csv格式,方便我们后续利用python进行数据分析:
导出后的结果在程序同目录下的“data --> 聊天记录“文件中,我们需要csv文件,记住csv文件的地址,自此微信聊天记录爬取结束?。
PS:上述软件也可以进行数据分析,作者也贴出年度报告,各位可以尝试一下,不过内容较少且存在乱码。
二、内容分析可视化展示:
环境配置:python3.8(3.10matplotlib不兼容问题) numpy pandas seaborn jieba july wordcloud
接下来直接内容分析代码,代码中需要根据你的CSV文件地址修改以及聊天双方名字修改:

文件中引用有停词文件,可以从GitHub上下载你想使用的(差不多都一样,可以在文件中添加新的屏蔽词语)。停词文件和代码文件放在同一目录下:
GitHub - goto456/stopwords: 中文常用停用词表(哈工大停用词表、百度停用词表等)
然后直接运行代码就可以等着一张一张的图片展示啦??
