目录
一、目标
爬取链接我的书架 -17K小说网，并将书架信息中的作品的分类、书名、最新章节、作者这些信息一一存储在 Mysql 数据库中。
二、分析
发现要先登录才能进入页面，所以到时候要用到 Cookies 和 Session，登录后：右键，检查 --> 点击Network，ctrl+r刷新数据包(已刷新点击两下上方红色按钮)，找到下方数据包发现信息没有呈现出来。(用的是谷歌浏览器)
在这里，先考虑 Ajax 数据，点击下方红色标记处，寻找一番，找到数据所在。Ajax 可看5.2 Ajax 数据爬取实战-CSDN博客。
在 response 中分析数据，就可开始爬取。
因为是登录后的爬取，所以需要设置 headers，cookies等，这些可以直接在上图文件的 Headers 中寻找。
三、代码
