[油猴脚本] 小红书一键导出收藏+一键下载单个笔记内容
本帖最后由 bootislands 于 2023-9-26 13:42 编辑该脚本在电脑端使用。功能主要分两部分：
1. 「导出小红书账号里的收藏」。使用方法可以看作者录制的教程视频：https://www.bilibili.com/video/BV1Fo4y177pv/
主要是导出你自己的收藏。如果别人的收藏公开可见的话，也可以导出别人的。
2. 「一键下载单条笔记的内容（包括图片 视频 笔记文字，但不包括评论区）」。使用方法：点进单个笔记的页面，右下角就会出现下载按钮
楼主个人很喜欢这个脚本，因为理论上它够安全，不像一些爬虫大批量发送请求（这样很容易被封号），相反，功能1只抓取收藏页面的现成数据，不额外再发请求，功能2也只是下载单条笔记内容，因此很安全（只是理论上，万一你中奖了别找楼主负责）
注：这个脚本不能批量爬取某个博主发的笔记。如果你需要这种高风险功能，可以看看另一个项目：https://github.com/xisuo67/XHS-Spider 它功能更强，相应地被封号概率也更高

``` 请问导出的内容，是按照笔记标题生成不同文件夹吗 ？ 感谢分享，正好想保存几篇笔记，下来试试 谢谢楼主 不喜欢批量的 就喜欢这种脚本 感谢楼主的分享我来试用一下！ 感谢分享
不错的脚本，先收藏一下 哥们 点赞收藏评论呢？？这些数据 感谢楼主分享 感谢分享
