一、登录Cloudflare Workers
二、创建Workers
三、部署
方法一:

// git使用cnpmjs镜像、分支文件使用jsDelivr镜像的开关,0为关闭,默认开启

复制index.js到左侧框
然后部署即可
index.js默认配置下clone走github.com.cnpmjs.org,项目文件会走jsDeliver,如需走worker,修改Config变量即可
以下都是合法输入:
- 分支源码:https://github.com/hunshcn/project/archive/master.zip
- release源码:https://github.com/hunshcn/project/archive/v0.1.0.tar.gz
- release文件:https://github.com/hunshcn/project/releases/download/v0.1.0/example.zip
- 分支文件:https://github.com/hunshcn/project/blob/master/filename
- commit文件:https://github.com/hunshcn/project/blob/1111111111111111111111111111/filename

方法二:
复制index.js,使用方法的上面一样
//github域名
const upstream = 'github.com'
//若有移动端则更改,否则与上面一样
const upstream_mobile = 'github.com'
// 密码访问
const openAuth = false
const username = 'moluo'
const password = '123456'
// 你希望禁止哪些国家访问
const blocked_region = ['RU']
// 禁止自访问
const blocked_ip_address = ['0.0.0.0', '127.0.0.1']
// 替换成你想镜像的站点
const replace_dict = {
'$upstream': '$custom_domain',
'//github.com': ''
}
