PeerJS部署在Heroku上监听EACCES：权限被拒绝0.0.0.0:443

时间：2020-10-10 16:20:32

标签： javascript express heroku deployment peerjs

我正在使用peerJS进行视频通话功能，这是我的package.json 

{
  "name": "zoom-clone",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "concurrently \"node server.js\" \"peerjs --port 443\""
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "concurrently": "^5.3.0",
    "ejs": "^3.1.3",
    "express": "^4.17.1",
    "peer": "^0.5.3",
    "socket.io": "^2.3.0",
    "uuid": "^8.1.0"
  },
  "devDependencies": {
    "nodemon": "^2.0.4"
  }
}

它们是2个服务器（express服务器和peerjs云服务器），所以我正在使用npm软件包调用concurrently来组合2个启动命令

当它正在开发环境中时，它可以完美地工作，我可以接听并回答来自其他用户加入我房间的呼叫，但是当我将其部署在Heroku上时，我需要更改peerJS选项，这就是这种情况

const myPeer = new Peer(undefined, {
  host: 'https://video-call-1205.herokuapp.com',
  port: '443'
})

我将主机更改为我部署的网站和默认端口443（端口443用于https，然后我添加了secure: true，但它没有任何变化，因此我将其删除了。）

部署后，它无法像在开发环境中一样显示新用户的视频流到我的房间，并且在我heroku logs --tails时返回此视频：

看起来无法访问PeerJS的云服务器

请告诉我如何解决它，非常感谢，并祝您愉快

更新：我发现端口<1024是呼叫保留端口，并且不允许使用它们，然后将端口更改为8081，它仍然出现相同的错误，就像部署时的端口一样尚未受到影响。

this is my `server.js`
const express = require('express')
const app = express()
const server = require('http').Server(app)
const io = require('socket.io')(server)
const { v4: uuidV4 } = require('uuid')
var PORT = process.env.PORT || 3000
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 })
})

io.on('connection', socket => {
  socket.on('join-room', (roomId, userId) => {
    socket.join(roomId)
    socket.to(roomId).broadcast.emit('user-connected', userId)

    socket.on('disconnect', () => {
      socket.to(roomId).broadcast.emit('user-disconnected', userId)
    })
  })
})

server.listen(PORT, () => {
  console.log(PORT, 'is listening')
})

这是客户端上的文件script.js，我在客户端上使用peerJS 

const socket = io('/')
const videoGrid = document.getElementById('video-grid')
const myPeer = new Peer(undefined, {
  host: '/',
  port: '9000'
})
const myVideo = document.createElement('video')
myVideo.muted = true
const peers = {}
navigator.mediaDevices
  .getUserMedia({
    video: true,
    audio: false
  })
  .then(stream => {
    addVideoStream(myVideo, stream)

    myPeer.on('call', call => {
      call.answer(stream)
      const video = document.createElement('video')
      call.on('stream', userVideoStream => {
        console.log(userVideoStream)
        addVideoStream(video, userVideoStream)
      })
    })

    socket.on('user-connected', userId => {
      connectToNewUser(userId, stream)
    })
  })

socket.on('user-disconnected', userId => {
  if (peers[userId]) {
    console.log('user disconnected', userId)
    console.log('peers', peers)

    peers[userId].close()
  }
})

myPeer.on('open', id => {
  socket.emit('join-room', ROOM_ID, id)
})

function connectToNewUser (userId, stream) {
  const call = myPeer.call(userId, stream)
  const video = document.createElement('video')
  call.on('stream', userVideoStream => {
    addVideoStream(video, userVideoStream)
  })
  call.on('close', () => {
    video.remove()
  })

  peers[userId] = call
  console.log('peers', peers)
}

function addVideoStream (video, stream) {
  video.srcObject = stream
  video.addEventListener('loadedmetadata', () => {
    video.play()
  })
  videoGrid.append(video)
}

谢谢你帮我，祝你有美好的一天
