【问题描述】：
我花了一整天的时间在网上寻找错误的解决方案
到 'wss://localhost/myapp/peerjs?key=peerjs&id=5c70da87-62c1-41dd-b1b1-e7aea5acc09b&token=j4n0nprnu6' 的 WebSocket 连接失败：在收到握手响应之前连接已关闭
我正在 express 服务器上开发这个 nodejs 应用程序。我在其中初始化 PeerServer 的快递服务器：
// Dependencies
const express = require('express')
const app = express()
const httpPort = process.env.PORT || 80
const httpsPort = 443
const { ExpressPeerServer } = require('peer')
const path = require('path')
const http = require('http')
const https = require('https')
const fs = require('fs')
// Certificate & credentials
const privateKey = fs.readFileSync(path.join(__dirname, 'certs', 'key.pem'))
const certificate = fs.readFileSync(path.join(__dirname, 'certs', 'cert.pem'))
const credentials = {
key: privateKey,
cert: certificate
}
const mainServer = http.createServer(app).listen(httpPort, () => { console.log('Main Server listening to port ' + httpPort) })
const httpsServer = https.createServer(credentials, app).listen(httpsPort, () => { console.log('Peer Server listening to port ' + httpsPort) })
const peerServer = ExpressPeerServer(mainServer, {
debug: true,
path: '/myapp'
})
//app.use('peerjs', peerServer)
app.use(peerServer)
const io = require('socket.io')(httpsServer)
const { v4: uuidV4 } = require('uuid')
app.set('view engine', 'ejs')
app.use(express.static('public'))
app.get('/', (req, res) => {
res.redirect(`/${uuidV4()}`)
})
app.get('/:room', (req, res) => {
res.render('room', { roomId: req.params.room })
//console.log('Room Created / Joined')
})
io.on('connection', (socket) => {
//console.log('IO Connectedd')
socket.on('join-room', (roomId, userId) => {
console.log(roomId, userId)
socket.join(roomId)
socket.to(roomId).emit('user-connected', userId)
socket.on('disconnect', () => {
socket.to(roomId).emit('user-disconnected', userId)
})
})
})
下面是我的客户端代码
const socket = io('/')
const videoGrid = document.getElementById('video-grid')
const myPeer = new Peer(undefined, {
host: '/',
port: '443',
path: '/myapp'
})
const ownVideo = document.createElement('video') // Own Video
ownVideo.muted = true
const peers = {}
navigator.mediaDevices.getUserMedia({
video: true,
audio: true
}).then(stream => {
addVideoStream(ownVideo, stream)
myPeer.on('call', call => { // On Receiving Other Persons Call
call.answer(stream) // Send Video Stream On Answer
const video = document.createElement('video')
call.on('stream', userVideoStream => { // Send Back Video Stream On Stream
addVideoStream(video, userVideoStream)
})
})
socket.on('user-connected', userId => { // Allow Self To Be Connected To Others
console.log('User Connected: ' + userId)
connectToNewUser(userId, stream)
})
})
socket.on('user-disconnected', userId => {
if (peers[userId]) peers[userId].close()
})
myPeer.on('open', id => {
socket.emit('join-room', ROOM_ID, id)
})
function connectToNewUser(userId, stream) {
const call = myPeer.call(userId, stream) // We Connect To Other User
const video = document.createElement('video')
call.on('stream', userVideoStream => { // Other User Connects To Us
addVideoStream(video, userVideoStream)
})
call.on('close', () => { // Other User Disconnects
video.remove()
})
peers[userId] = call
}
function addVideoStream(video, stream) {
video.srcObject = stream
video.addEventListener('loadedmetadata', () => {
video.play()
})
videoGrid.append(video)
}
我是 nodejs 新手，在网上找不到任何解决方案。
请帮忙！！

显示文件层次结构和 SSL 证书来源。

我们需要您的 room.ejs 文件来确定答案
