+ * @description 打包时采用`cdn`模式，仅限外网使用（默认不采用，如果需要采用cdn模式，请在 .env.production 文件，将 VITE_CDN 设置成true）
+ * 平台采用国内cdn：https://www.bootcdn.cn，当然你也可以选择 https://unpkg.com 或者 https://www.jsdelivr.com
+ * 提醒：mockjs不能用cdn模式引入，会报错。正确的方式是，生产环境删除mockjs，使用真实的后端请求
+ * 注意：上面提到的仅限外网使用也不是完全肯定的，如果你们公司内网部署的有相关js、css文件，也可以将下面配置对应改一下，整一套内网版cdn
