09.提炼总结的爬虫知识体系

这是根据爬虫实战相关的书籍作者写的一篇系统介绍爬虫的文章里提炼的导图(附录),可以更直观的看明白爬虫所涉及到的内容和知识。

前些天听王伟健说他过往用selenium来每5分钟检测淘宝数以万计的竞品动态,那selenium真是神器啊,完全的突破了js的渲染,模拟完全真实的可见数据。

在整个流程上,还欠缺的几个板块:

在基本的爬虫应用,即数据解析和数据存储上,

app的爬取上用到hook和mitmproxy;

数据存储上,应学会几个基本数据库;

提高效率上,需要学会多进程、多线程、协程;

分布式上学会scrapy框架;

反爬破解上,学会深度学习、换代理、换终端;

上面5个内容,刚好差不多用5天时间去消化和学习。
