利用反代CDN加速网站

通过Deno的cdn加速自己的网站

将deno的服务器作为中转相当于给自己的网站加了cdn

1.初始条件：

注册一个 github 账号并且 github 账号有一个月以上
注册一个 deno 账号

2.部署服务

新建项目并输入如下代码

mport { serve } from "https://deno.land/[email protected]/http/server.ts";

const targetWSHost = "xx.xxx.xxxx";
async function handler(req: Request): Promise<Response> {
  const url = new URL(req.url);
  const upgrade = req.headers.get("upgrade") || "";
  if (upgrade.toLowerCase() != "websocket") {
    url.host = targetWSHost;
    return await fetch(url, req);
  }

  const socketPromse = [];
  const { socket: downstream, response } = Deno.upgradeWebSocket(req);
  downstream.addEventListener("open", ()=>{
    console.log('open----downstream-------');
  })
  url.host = targetWSHost
  url.protocol = 'wss';
  url.port = '443'
  const upstream = new WebSocket(url);
  socketPromse.push(new Promise((resolve) => upstream.addEventListener("open", resolve)));
  await Promise.all(socketPromse);
  console.log("Both WebSocket connections are open");
  downstream.addEventListener("message", (message: any) => {
    upstream.send(message.data);
  });
  downstream.addEventListener("error", (error: any) => {
    console.log("error", error);
  });

  // Proxy messages from the upstream WebSocket connection to the downstream connection
  upstream.addEventListener("message", (message: any) => {
    downstream.send(message.data);
  });
  upstream.addEventListener('error', (e: any) => {
    console.log("error", e);
  });
  return response;
}

serve(handler);

deno 多账号轮询

import { serve } from "https://deno.land/[email protected]/http/server.ts";


const targetWSHosts = [
  "hello-world-silent-mode-def6.b2l48k4lr8o.workers.dev",
  "hello-world-quiet-hat-1527.b2l48k4lr8o.workers.dev"
];
async function handler(req: Request): Promise<Response> {
  // 选择一个target host
  const targetHost = targetWSHosts[Math.floor(Math.random() * targetWSHosts.length)];
  const url = new URL(req.url);
  url.host = targetHost;
  const upgrade = req.headers.get("upgrade") || "";
  if (upgrade.toLowerCase() != "websocket") {
    url.host = targetHost;
    return await fetch(url, req);
  }

  const socketPromse = [];
  const { socket: downstream, response } = Deno.upgradeWebSocket(req);
  downstream.addEventListener("open", ()=>{
    console.log('open');
  })
  url.host = targetHost;
  url.protocol = 'wss';
  url.port = '443'
  const upstream = new WebSocket(url);
  socketPromse.push(new Promise((resolve) => upstream.addEventListener("open", resolve)));
  await Promise.all(socketPromse);
  // console.log("Both WebSocket connections are open");
  downstream.addEventListener("message", (message: any) => {
    upstream.send(message.data);
  });
  downstream.addEventListener("error", (error: any) => {
    console.log("error", error);
  });

  // messages from the upstream WebSocket connection to the downstream connection
  upstream.addEventListener("message", (message: any) => {
    downstream.send(message.data);
  });
  upstream.addEventListener('error', (e: any) => {
    console.log("error", e);
  });
  return response;
}

serve(handler);

Cloudflare Pages多账户反代代码

将cloudflare的服务器作为中转相当于给自己的网站加了cdn

1,操作注意点：

无论使用“项目代码拉取模式”、“文件夹目录上传模式”还是“ZIP 压缩上传模式”，请把文件名称一律改为_worker.js(js 格式)，视频教程中已演示
修改_worker.js 中的 url.hostname="app.example.com"中的 app.example.com 为你要反代的网址
使用本地上传模式时，你可能犹豫是先改 js 文件名，还是先改文件内的代码？无所谓先后，随意
以下三个多账户代码取自网络上 workers 反代的多账户写法，并参考 Pages 单账户反代代码项目

建议：比如 heroku 双账号，一般选择单双日轮换，可分别用两个账号的应用程序名（代理协议、PATH 路径、UUID 保持一致），单双号天分别执行，那一个月就有 550+550 小时，heroku 一个账户默认每月最多免费使用 550 小时

以下代码你也可以放置在 Github 上，只要在 Github 上更改网址，最终的 pages 反代内容会自动同步你的更改
