今天教大家一种新的关于 CloudFlare Worker 的玩法 - 利用 Cloudflare Worker 搭建镜像网站！

需要注册CloudFlare账号(这里简称：CF )

搭建教程

1. 点击创建 Worker

2. 创建完毕后，点击编辑代码：将原有的示例代码全部删除

3. 将下方代码全部粘贴到代码框里，如下图所示：

复制代码

// 反代目标网站.
const upstream = 'lb5.net'
// 反代目标网站的移动版.
const upstream_mobile = 'lb5.net'
// 访问区域黑名单（按需设置）.
const blocked_region = ['TK']
// 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',
'//archiveofourown.org': ''
}
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)) {
var upstream_domain = upstream;
} else {
var 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;

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') {

} else if (i == '$custom_domain') {

}
if (j == '$upstream') {

} else if (j == '$custom_domain') {

}
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;
}

const upstream = '你需要镜像的网站域名'
const upstream_mobile = '你需要镜像的网站的移动版'
const blocked_region = ['访问区域黑名单（按需设置）']
const blocked_ip_address = ['IP地址黑名单（按需设置）', '127.0.0.1']

粘贴好后按需修改上方参数，修改好之后，点击保存并部署
