我找不到一个完全类似的职位，所以我在这里问。
我尝试使用相同的端口为我的安全WebSocket（wss）和快速应用程序。但是当我使用A）app.listen（）--〉socket breaks B）当我使用server.listen（）=〉快速breaks。我被迫用不同的端口做两次侦听。不理想。

const app = express()
const server = https.createServer({ key, cert }, app);  
const wss = new WebSocket.Server({ server})

wss.on ...

server.listen(3002);
app.listen(3001);

我试着只保留server.listen，套接字工作，但express中断。反之亦然，也会中断另一个。双端口是唯一的出路吗？但这意味着我的负载平衡器，我必须分裂它。
我没有这个问题与正常的ws.只有发生与安全的websockets ws.
当我删除应用程序。听它给我一个“xxx没有发送任何数据”x1c 0d1x
当我把它加回去（但在不同的端口上）时，它就像预期的那样工作了。
下面是我的全部代码的大部分

const WebSocket = require('ws');
const fs = require('fs');

const https = require('https');
const express = require('express')
require('dotenv').config()
const keypath = process.env.environment=="production" ? process.env.key : 'localhost.key';
const certpath = process.env.environment=="production" ? process.env.cert : 'localhost.crt';
console.log("environment is ",process.env.environment)
const key = fs.readFileSync(keypath);
const cert = fs.readFileSync(certpath);
const bodyParser = require('body-parser')
const mongoose = require('mongoose')
const cors = require('cors')
const helmet = require('helmet')
const morgan = require('morgan')

const app = express()

app.use(helmet())
app.use(bodyParser.json())

    .connect(process.env.MONGO_URI, {
        useNewUrlParser: true,
        useUnifiedTopology: true,
    })
    .then(() => console.log('MongoDB connected!'))
    .catch((err) => console.log(err))

app.use('/api/world', worldRoutes)
app.use('/', baseRoutes)
const PORT = process.env.PORT || 3002

const server = https.createServer({ key, cert }, app);  
const wss = new WebSocket.Server({ server})
wss.on('connection', (ws, req) => {
    console.log('received socket connection ', req.headers['sec-websocket-key'])
...
})

server.listen(3002);
app.listen(PORT);

  console.log('Server is listening on port ' + PORT);

//not sure if needed
// server.on('upgrade', (request, socket, head) => {
//     wss.handleUpgrade(request, socket, head, (socket) => {
//         wss.emit('connection', socket, request)
//     })
// })
