Cloudflare cf使用worker搭建一个简单的免费页面反代系统，不符合HTTP协议标准规范但是能凑合用，腾讯云函数

比如说，无法响应206等状态码，仅支持200输出
放入worker即可使用，无需更改。api接口:worker链接/api,user接口：worker链接/user

自己有服务器，想用kangle搭建一个网络更快的，只需操作文章中说的“国内服务器"
https://bbs.itzmx.com/thread-100060-1-1.html

用kangle自建时建议hosts文件绑定国内备案域名用国内反代服务器，需要使用https，例如反代地址 pikpak.oss-cn-hangzhou.aliyuncs.com 证书文件要在电脑上受信一下
