Lance-gg游戏socket.io无法在数字海洋上加载资源

Question

我的 lance-gg 游戏可以在本地主机上运行，但现在我尝试在数字海洋上部署，该网站似乎正在托管，但我无法连接 socket.io。客户端浏览器的错误是：

[Error] Failed to load resource: The request timed out. (socket.io, line 0) http://144.126.196.39:3001/socket.io/?EIO=3&transport=polling&t=NOU8Lc-

服务器代码是：

import path from 'path';

import express from 'express';

import socketIO from 'socket.io';

import { Lib, ServerEngine, GameEngine } from 'lance-gg';

// define routes and socket

const server = express();

server.get('/', (req, res) => { res.sendFile(path.join(__dirname, '../dist/index.html')); });

server.use('/', express.static(path.join(__dirname, '../dist/')));

let requestHandler = server.listen(3001);

const io = socketIO(requestHandler);

// Game Instances

const gameEngine = new GameEngine({ traceLevel: Lib.Trace.TRACE_NONE });

const serverEngine = new ServerEngine(io, gameEngine, { debug: {}, updateRate: 12 });

serverEngine.start();

客户端代码是：

import { Renderer, GameEngine, ClientEngine } from 'lance-gg';

const options = {

    delayInputCount: 3,

    scheduler: 'render-schedule',

    syncOptions: {

        sync: 'extrapolate',

        remoteObjBending: 0.8,

        bendingIncrements: 12

    },

    serverURL: 'http://144.126.196.39:3001'

};

// create a client engine and a game engine

const gameEngine = new GameEngine(options);

const clientEngine = new ClientEngine(gameEngine, options, Renderer);

document.addEventListener('DOMContentLoaded', (e) => clientEngine.start());

我了解 digital ocean 中的 nodeJS 入门模板使用 Nginx，因此我确保使用端口 3001 重定向到我的应用程序。

server {

        listen 80 default_server;

        listen [::]:80 default_server;

        root /var/www/moon-game-2;

        index index.html index.htm index.nginx-debian.html;

        server_name hellonode;

        location ^~ /assets/ {

                gzip_static on;

                expires 12h;

                add_header Cache-Control public;

        }

我怎样才能让我的socket.io也连接到我的lance-gg服务器？

没关系，解决了我在客户端代码中的问题。显然，在云环境中，我不需要像在本地主机上那样指定端口 3001。// ...import { USE_CLOUD_SERVER } from './constants';const options = {    // ...    // The cloud server is set up with Nginx to redirect to the right port.    serverURL: USE_CLOUD_SERVER ? 'http://144.126.196.39' : 'http://localhost:3001'};// ...
