- 绑定你的域名到 cloudflare
- 创建一个 worker，并写入如下代码：
// 反代目标网站.const upstream ='github.com';// 反代目标网站的移动版.const upstream_mobile ='github.com';// 访问区域黑名单（按需设置）.const blocked_region =[''];// IP地址黑名单（按需设置）.const blocked_ip_address =['0.0.0.0','127.0.0.1'];// 路径替换.const replace_dict ={'$upstream':'$custom_domain',// 将"$upstream"替换为"$custom_domain"'//github.com':''// 移除路径中的"//github.com"};addEventListener('fetch',event=>{ event.respondWith(fetchAndApply(event.request));});asyncfunctionfetchAndApply(request){const region = request.headers.get('cf-ipcountry').toUpperCase();// 获取访问者所在的地区const ip_address = request.headers.get('cf-connecting-ip');// 获取访问者的IP地址const user_agent = request.headers.get('user-agent');// 获取访问者的User-Agent头部信息let response =null;let url =newURL(request.url);let url_host = url.host;if(url.protocol =='http:'){// 如果请求协议是HTTP，则重定向到HTTPS url.protocol ='https:'; response = Response.redirect(url.href);return response;}if(awaitdevice_status(user_agent)){// 判断是否为移动设备var upstream_domain = upstream;}else{var upstream_domain = upstream_mobile;} url.host = upstream_domain;if(blocked_region.includes(region)){// 检查访问区域是否在黑名单中 response =newResponse('Access denied: WorkersProxy is not available in your region yet.',{status:403});}elseif(blocked_ip_address.includes(ip_address)){// 检查IP地址是否在黑名单中 response =newResponse('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 =newHeaders(request_headers); new_request_headers.set('Host', upstream_domain);// 设置请求头的Host字段为反代目标网站的域名 new_request_headers.set('Referer', url.href);// 设置请求头的Referer字段为当前请求的URLlet original_response =awaitfetch(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 =newHeaders(response_headers);let status = original_response.status;// 修改响应头的设置 new_response_headers.set('cache-control','public, max-age=14400'); 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 && content_type.includes('text/html')&& content_type.includes('UTF-8')){ original_text =awaitreplace_response_text(original_response_clone, upstream_domain, url_host);// 替换响应中的文本内容}else{ original_text = original_response_clone.body;} response =newResponse(original_text,{ status,headers: new_response_headers });}return response;}asyncfunctionreplace_response_text(response, upstream_domain, host_name){let text =await response.text();for(let i in replace_dict){let j = replace_dict[i];if(i =='$upstream'){ i = upstream_domain;}elseif(i =='$custom_domain'){ i = host_name;}if(j =='$upstream'){ j = upstream_domain;}elseif(j =='$custom_domain'){ j = host_name;}let re =newRegExp(i,'g'); text = text.replace(re, j);// 使用正则表达式替换文本内容}return text;}asyncfunctiondevice_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;} - 自定义域名，方便访问
