如果是之前博客的老读者，那么相信对Deno Deploy不太陌生。之前的教程我利用Deno Deploy，给大家做了反代网站的教程。但是有些小伙伴是想使用反代来代理WebSocket节点的。不过，我们得感谢zizifn这位作者，让我们在Deno Deploy反代WebSocket节点变成了可能。在这篇教程中，我来和大家讲解一下如何使用Deno Deploy反代Websocket节点
准备材料
- GitHub 账号
部署步骤
- 打开Deno Deploy的官网：https://deno.com/deploy ，点击“Sign up”进行注册。如有账号点击“Sign in”登录
- 点击“New Project”按钮，创建一个项目
- 点击“Play”按钮，创建一个新的项目
- 将代码修改为下面的内容，然后点击“Save and deploy”按钮（将
xx.xxx.xxxx替换成实际的节点地址）
import { serve } from "https://deno.land/std@0.177.0/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);
