使用jsoup抓取京东数据

只用于学习交流,私自用于其他途径,后果自负!!!

目前只抓取零食相关的数据,现在就只需要零食相关的数据,其他后续再议!

抓取零食相关的目的就是为了这个vipsnacks项目的后续开发。

项目需要

  • httpclient
  • jsoup
  • slf4j
  • selenium
  • phantomjs
  • WebCollector

更新日志

  • 初始化项目,完成一,二级类目的抓取 (2017-05-24)
  • 采用selenium获取页面数据,获取三,四,五级类目(2017-05-25)
  • 多线程并发爬取类目分页数据(2017-05-26)
  • 多线程爬取商品skuid(2017-05-28)

selenium这个爬取的速度太慢了,而且每次还要打开一个网页,抓取少量数据还可以用一用,多的话实在罩不住,近期在找别的方法爬取

  • 使用WebCollector+selenium+phantomjs爬取商品(2017-06-01只爬取一个类目测试)
  • 数据入库测试(2017-06-02)
  • 测试爬取一个小类目,爬取20万数据用时21分钟(2017-06-03)
  • 数据正常入库,爬取数据285330条(2017-06-04)
  • 优化获取商品代码,从获取一页要19664毫秒,优化到现在获取一页商品要7000毫秒左右,(2017-06-07)

觉得不错的朋友可以点下star,watch,fork也算是对我的鼓励了。
