由于穷，买不起服务器，但是又想上古狗，所以我把目光瞄向了Cloudflare的Worker，因为他可以镜像古狗，然后我就可以抛弃百度用古狗啦！！
什么是Cloudflare Worker？
在他们的博客上是这么说的
原话:
Cloudflare Workers provides a serverless execution environment that allows you to create entirely new applications or augment existing ones without configuring or maintaining infrastructure.
翻译:
Cloudflare Workers提供了一种无服务器执行环境，使您无需配置或维护基础架构即可创建全新的应用程序或扩充现有的应用程序。
开始镜像
我们建议直接使用Cloudflare自带域名（我怕用我自己的域名被墙）
1.注册账号
我们需要注册一个Cloudflare账号（太简单，懒得写）
2.创建Worker
打开 网页链接 点击Log in，在下面输入你的域名前缀
点击Set up后选择Free白嫖免费套餐
然后点击Create a Worker
在下面页面中输入
[js] // 替换成你想镜像的站点 const upstream = ‘www.xxx.com‘ // 如果那个站点有专门的移动适配站点，否则保持和上面一致 const upstream_mobile = ‘www.xxx.com‘ // 你希望禁止哪些国家访问 const blocked_region = [‘KP’, ‘SY’, ‘PK’, ‘CU’] // 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’, ‘//google.com’: ‘’ } //以下内容都不用动 addEventListener(‘fetch’, event => { event.respondWith(fetchAndApply(event.request)); }) async function fetchAndApply(request) { const region = request.headers.get(‘cf-ipcountry’).toUpperCase(); const ip_address = request.headers.get(‘cf-connecting-ip’); const user_agent = request.headers.get(‘user-agent’); let response = null; let url = new URL(request.url); let url_host = url.host; if (url.protocol == ‘http:’) { url.protocol = ‘https:’ response = Response.redirect(url.href); return response; } if (await device_status(user_agent)) { upstream_domain = upstream } else { upstream_domain = upstream_mobile } url.host = upstream_domain; if (blocked_region.includes(region)) { response = new Response(‘Access denied: WorkersProxy is not available in your region yet.’, { status: 403 }); } else if(blocked_ip_address.includes(ip_address)){ response = new Response(‘Access denied: Your IP address is blocked by WorkersProxy.’, { status: 403 }); } else{ let method = request.method; let request_headers = request.headers; let new_request_headers = new Headers(request_headers); new_request_headers.set(‘Host’, upstream_domain); new_request_headers.set(‘Referer’, url.href); let original_response = await fetch(url.href, { method: method, headers: new_request_headers }) let original_response_clone = original_response.clone(); let original_text = null; let response_headers = original_response.headers; let new_response_headers = new Headers(response_headers); let status = original_response.status; new_response_headers.set(‘access-control-allow-origin’, ‘*‘); new_response_headers.set(‘access-control-allow-credentials’, true); new_response_headers.delete(‘content-security-policy’); new_response_headers.delete(‘content-security-policy-report-only’); new_response_headers.delete(‘clear-site-data’); const content_type = new_response_headers.get(‘content-type’); if (content_type.includes(‘text/html’) && content_type.includes(‘UTF-8’)) { original_text = await replace_response_text(original_response_clone, upstream_domain, url_host); } else { original_text = original_response_clone.body } response = new Response(original_text, { status, headers: new_response_headers }) } return response; } async function replace_response_text(response, upstream_domain, host_name) { let text = await response.text() var i, j; for (i in replace_dict) { j = replace_dict[i] if (i == ‘$upstream’) { i = upstream_domain } else if (i == ‘$custom_domain’) { i = host_name } if (j == ‘$upstream’) { j = upstream_domain } else if (j == ‘$custom_domain’) { j = host_name } let re = new RegExp(i, ‘g’) text = text.replace(re, j); } return text; } async function device_status (user_agent_info) { var agents = [“Android”, “iPhone”, “SymbianOS”, “Windows Phone”, “iPad”, “iPod”]; var flag = true; for (var v = 0; v < agents.length; v++) { if (user_agent_info.indexOf(agents[v]) > 0) { flag = false; break; } } return flag; } [/js]
最后点击’Save and Deploy‘即可！
完成！
