标题中的“加快”是指通常在国内线路不好情况下更优的连接到Github,不同情况有不同的效果,想要速度达到极致,影响因素有:自己的网络、可通过自己的域名来套上CDN连接Workers,自选cloudflare节点IP等等

文章末还有一些Workers的玩法

一、登录Cloudflare Workers

https://dash.cloudflare.com/

二、创建Workers

三、部署

方法一:

index.js:https://github.com/hunshcn/gh-proxy

'use strict'

/**
 * static files (404.html, sw.js, conf.js)
 */
const ASSET_URL = 'https://hunshcn.github.io/gh-proxy/'
// 前缀,如果自定义路由为example.com/gh/*,将PREFIX改为 '/gh/',注意,少一个杠都会错!
const PREFIX = '/'
// 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
const Config = {
    jsdelivr: 1,
    cnpmjs: 1
}

/** @type {RequestInit} */
const PREFLIGHT_INIT = {
    status: 204,
    headers: new Headers({
        'access-control-allow-origin': '*',
        'access-control-allow-methods': 'GET,POST,PUT,PATCH,TRACE,DELETE,HEAD,OPTIONS',
        'access-control-max-age': '1728000',
    }),
}

/**

 * @param {number} status
 * @param {Object<string, string>} headers
 */
function makeRes(body, status = 200, headers = {}) {
    headers['access-control-allow-origin'] = '*'
    return new Response(body, {status, headers})
}


/**

 */
function newUrl(urlStr) {
    try {
        return new URL(urlStr)
    } catch (err) {
        return null
    }
}

    if (path.search(exp1) === 0 || !Config.cnpmjs && (path.search(exp3) === 0 || path.search(exp4) === 0)) {
        return httpHandler(req, path)
    } else if (path.search(exp2) === 0) {

    } else if (path.search(exp4) === 0) {
        const newUrl = path.replace(/(?<=com\/.+?\/.+?)\/(.+?\/)/, '@$1').replace(/^(?:https?:\/\/)?raw\.githubusercontent\.com/, 'https://cdn.jsdelivr.net/gh')
        return Response.redirect(newUrl, 302)
    } else {
        return fetch(ASSET_URL + path)
    }
}


/**

 */
function httpHandler(req, pathname) {
    const reqHdrRaw = req.headers

    // preflight
    if (req.method === 'OPTIONS' &&

    ) {

    }

    let rawLen = ''

    const reqHdrNew = new Headers(reqHdrRaw)

    let urlStr = pathname
    if (urlStr.startsWith('github')) {

        redirect: 'follow',
        body: req.body
    }
    return proxy(urlObj, reqInit, rawLen, 0)
}


/**
 *
 * @param {URL} urlObj
 * @param {RequestInit} reqInit
 */
async function proxy(urlObj, reqInit, rawLen) {
    const res = await fetch(urlObj.href, reqInit)
    const resHdrOld = res.headers
    const resHdrNew = new Headers(resHdrOld)

    // verify
    if (rawLen) {
        const newLen = resHdrOld.get('content-length') || ''
        const badLen = (rawLen !== newLen)

        if (badLen) {
            return makeRes(res.body, 400, {
                '--error': `bad len: ${newLen}, except: ${rawLen}`,
                'access-control-expose-headers': '--error',
            })
        }
    }
    const status = res.status
    resHdrNew.set('access-control-expose-headers', '*')
    resHdrNew.set('access-control-allow-origin', '*')

    resHdrNew.delete('content-security-policy')
    resHdrNew.delete('content-security-policy-report-only')
    resHdrNew.delete('clear-site-data')

    return new Response(res.body, {
        status,
        headers: resHdrNew,
    })
}

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:

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 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': ''
}
