简书作者信息统计

本文首发于我的个人博客：尾尾部落

从2016年就开始在简书上写文章，之所以选择这个平台，很大程度上是因为它洁简的后台输入界面，支持MD，非常适合写一些技术类的文章。

从最开始的零星几个粉丝，到粉丝数破百，到现在有700+粉丝，虽然离大牛们动辄数十万的粉丝还有很大的差距，但是看着粉丝数一天天上涨，感觉也很有成就感。于是就想着记录下粉丝数增涨的过程，以后当粉丝数上万后可以回头看看自己是怎么一步一步走到今天的（此处应该是意淫的表情）。但是，也许是简书太乞求简洁，后台都不提供作者粉丝数历史记录的，不像微信公众号、头条、熊掌号这些成熟的自媒体平台，都会给作者提供完善的相关数据记录，让作者可以清晰地跟踪自己粉丝数增长的曲线。

既然简书不提供，自己又希望有这个功能，又不想放弃简书这个平台，那就自己动手，丰衣足食吧。实现起来也很简单，思路如下：

1. 写个爬虫，每天定时爬取自己简书账号的各项指标数据（包括粉丝数、喜欢数、文章数等）
2. 写一个页面，用来做数据展示
3. 没了，就是这么简单。

Talk is cheap, Show you the code
上代码，这里附上爬虫的代码，展示页面做得还不是很完善，就不献丑了。
