    这是一个创建于 1671 天前的主题,其中的信息可能已经有所发展或是发生改变。
    虎嗅获取更多文章的 api 里面找不到和页数相关的参数,我试了提交 cookie 等,都只能获得第一页的数据,求大神指点

    补充一下:

    • 爬的网址:https://www.huxiu.com/channel/10.html
    • 接口没有和页数有关的参数 JIwo8K.png
    • 这是我第一次碰到这种情况,不知道虎嗅用了什么黑科技,求大神指点一二 QAQ

    这年头学爬虫也要学后端的

    这个接口看起来就是处理 offset 过大导致检索效率变低的问题, 常见套路一个是通过只查 id 的嵌套子查询来过滤; 另一个就是不使用 offset, 对连续文档列表的情况借助 last id 的方式. 后者复杂度更低一点
