今天发现 Butterfly 文档 有介绍自定义 CDN 的配置项，只需简单配置即可完成需求，所以之前写的东西 属于是 画蛇添足，参考价值不高

官方样例中的 cdn.staticfile.org CDN 加速由七牛云提供，技术社区掘金支持，可以直接填入使用

个人示例如下（主题配置文件）

# CDN
# Don't modify the following settings unless you know how they work
# 非必要請不要修改
CDN:
  # The CDN provider of internal scripts (主題內部 js 的 cdn 配置)
  # option: local/jsdelivr/unpkg/cdnjs/custom
  # Dev version can only choose. ( dev版的主題只能設置為 local )
  internal_provider: local

  # The CDN provider of third party scripts (第三方 js 的 cdn 配置)
  # option: local/jsdelivr/unpkg/cdnjs/custom
  # when set it to local, you need to install hexo-butterfly-extjs
  # third_party_provider: jsdelivr
  third_party_provider: custom

  # Add version number to CDN, true or false  
  version: false

  # Custom format
  # For example: https://cdn.staticfile.org/${cdnjs_name}/${version}/${min_cdnjs_file}
  custom_format: https://cdn.staticfile.org/${cdnjs_name}/${version}/${min_cdnjs_file}

想用 elemecdn 的话，custom_format 配置项该怎么写 我也不清楚。尝试写 https://npm.elemecdn.com/${name}${verType}/${file} 或 https://npm.elemecdn.com/${cdnjs_name}/${version}/${min_cdnjs_file} 都失败了

想用 elemecdn 的话，Butterfly 文档 给出了格式：

以下步骤已过时

前言

博客异常加载，f12发现 https://unpkg.com/swiper/swiper-bundle.min.js （主因）和 https://unpkg.com/@fancyapps/ui/dist/fancybox.umd.js 报 520（520，当源站服务器向 CDN 返回空白、未知或意外响应时，会发生 520 错误），日常都返的 200

基于此有了换 cdn 的想法。butterfly 官方教程 介绍了 local/jsdelivr/unpkg/cdnjs/custom 这些选择，都不是想要的，看到别人用的 Element cdn，学习一下

步骤

参考文章：butterfly官方教程#CDN、安知鱼 - 可用cdn整理、张洪 Heo - Butterfly CDN链接更改指南

修改源码：

  1. 修改 themes/butterfly/scripts/events/cdn.js，新增 elemecdn 字段

    elemecdn: `https://npm.elemecdn.com/${name}${verType}/${file}`,

  2. 修改 _config.butterfly.yml，CDN.third_party_provider

    f12 看了下 网络，替换后没异常

  3. 根据 张洪Heo：Butterfly CDN链接更改指南 按需替换 cdn链接（需注意变量名，比如butterfly v4.4.0 fontawesome 写成 fontawesomeV6 似乎才会生效 Butterfly v4.8.0 变量名已改为 fontawesome）
