综合自:开源最前线 、数据管道
最近国内一位开发者在 GitHub 上开源了个集众多数据源于一身的爬虫工具箱——InfoSpider,一不小心就火了!!!
有多火呢?开源没几天就登上GitHub周榜第四,标星1.3K,累计分支 172 个。同时作者已经开源了所有的项目代码及使用文档,并且在B站上还有使用视频讲解。
在这样一个信息爆炸的时代,每个人都有很多个账号,账号一多就会出现这么一个情况:个人数据分散在各种各样的公司之间,就会形成数据孤岛,多维数据无法融合,这个项目可以帮你将多维数据进行融合并对个人数据进行分析,这样你就可以更直观、深入了解自己的信息。
InfoSpider 是一个集众多数据源于一身的爬虫工具箱,旨在安全快捷的帮助用户拿回自己的数据,工具代码开源,流程透明。并提供数据分析功能,基于用户数据生成图表文件,使得用户更直观、深入了解自己的信息。
目前支持数据源包括GitHub、QQ邮箱、网易邮箱、阿里邮箱、新浪邮箱、Hotmail邮箱、Outlook邮箱、京东、淘宝、支付宝、中国移动、中国联通、中国电信、知乎、哔哩哔哩、网易云音乐、QQ好友、QQ群、生成朋友圈相册、浏览器浏览历史、12306、博客园、CSDN博客、开源中国博客、简书。
根据创建者介绍,InfoSpider 具有以下特性:
InfoSpider使用起来也非常简单,你只需要安装python3和Chrome浏览器,运行 python3 main.py,在打开的窗口点击数据源按钮, 根据提示选择数据保存路径,接着输入账号密码,就会自动爬取数据,根据下载的目录就可以查看爬下来的数据。
当然如果你想自己去练习和学习爬虫,作者也开源了所有的爬取代码,非常适合实战。
举个例子,比如爬取taobao的:
