我正在尝试创建自己的 PeerJS 服务器

Question

下面是代码，但我不知道我错过了什么

索引.js(充当服务器)

var path = require('path');
var express = require('express');
var routes = require('./routes');
var app = express();
app.use('/', routes);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
srv = app.listen(process.env.PORT)
app.use('./peerjs', require('peer').ExpressPeerServer(srv, {
debug: true
}));
srv.listen(process.env.PORT || 3000, function(){
console.log("Express server listening on port %d in %s mode", this.address().port, app.settings.env);
});

应用程序.js(主JS文件)

navigator.getUserMedia = (navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia);
//get browser cmopt
var me = {};
var myStream;
var peers = {};
init();
function init() {
if (!navigator.getUserMedia) return unsupported();
getLocalAudioStream(function(err, stream) {
if (err || !stream) return;
connectToPeerJS(function(err) {
if (err) return;
registerIdWithServer(me.id);
if (call.peers.length) callPeers();
else displayShareMessage();
});
});
} // initialization

function connectToPeerJS(cb) {
display('Connecting to PeerJS...');
//  me = new Peer({key: API_KEY});
var peer = new Peer({
host: location.hostname,
port: location.port || (location.protocol === 'https://rapidcom.herokuapp.com' ? 9000 : 80),
path: '/peerjs'
});
me.on('call', handleIncomingCall);
me.on('open', function() {
display('Connected.');
display('ID: ' + me.id);
cb && cb(null, me);
});// connect to peerJs Server and get ID From the Server
me.on('error', function(err) {
display(err);
cb && cb(err);
});
}

function registerIdWithServer() {
display('Registering ID with server...');
$.post('/' + call.id + '/addpeer/' + me.id);
} // Add our ID to the list of PeerJS IDs for this call

function unregisterIdWithServer() {
$.post('/' + call.id + '/removepeer/' + me.id);
}

function callPeers() {
call.peers.forEach(callPeer);
}
function callPeer(peerId) {
display('Calling ' + peerId + '...');
var peer = getPeer(peerId);
peer.outgoing = me.call(peerId, myStream);
peer.outgoing.on('error', function(err) {
display(err);
});
peer.outgoing.on('stream', function(stream) {
display('Connected to ' + peerId + '.');
addIncomingStream(peer, stream);
});
}

function handleIncomingCall(incoming) {
display('Answering incoming call from ' + incoming.peer);
var peer = getPeer(incoming.peer);
peer.incoming = incoming;
incoming.answer(myStream);
peer.incoming.on('stream', function(stream) {
addIncomingStream(peer, stream);
});
}// When someone initiates a call via PeerJS
// Add the new audio stream. Either from an incoming call, or from the response to one of our outgoing calls
function addIncomingStream(peer, stream) {
display('Adding incoming stream from .... ' + peer.id);
peer.incomingStream = stream;
playStream(stream);
}

function playStream(stream) {
var audio = $('<audio autoplay />').appendTo('body');
audio[0].src = (URL || webkitURL || mozURL).createObjectURL(stream);
}

function getLocalAudioStream(cb) {
display('Trying to access your microphone. Please click "Allow".');
navigator.getUserMedia (
{video: false, audio: true},
function success(audioStream) {
display('Microphone is open.');
myStream = audioStream;
if (cb) cb(null, myStream);
},
function error(err) {
display('Couldn't connect to microphone. Reload the page to try again.');
if (cb) cb(err);
}
);
}
function getPeer(peerId) {
return peers[peerId] || (peers[peerId] = {id: peerId});
}
function displayShareMessage() {
display('Give someone this URL to chat.');
display('<input type="text" value="' + location.href + '" readonly>');
$('#display input').click(function() {
this.select();
});
}
function unsupported() {
display("Your browser doesn't support getUserMedia.");
}
function display(message) {
$('<div />').html(message).appendTo('#display');
}

配置.js

{ 'iceServers': [{ 'url': 'stun:stun.l.google.com:19302' }] };

路线.js

var express = require('express');
var router = express.Router();
var config = require('./config');
var Call = require('./call'); 
// Create a new Call instance, and redirect
router.get('/new', function(req, res) {
var call = Call.create();
res.redirect('/' + call.id);
});
// Add PeerJS ID to Call instance when someone opens the page
router.post('/:id/addpeer/:peerid', function(req, res) {
var call = Call.get(req.param('id'));
if (!call) return res.status(404).send('Call not found');
call.addPeer(req.param('peerid'));
res.json(call.toJSON());
});
// Remove PeerJS ID when someone leaves the page
router.post('/:id/removepeer/:peerid', function(req, res) {
var call = Call.get(req.param('id'));
if (!call) return res.status(404).send('Call not found');
call.removePeer(req.param('peerid'));
res.json(call.toJSON());
});
// Return JSON representation of a Call
router.get('/:id.json', function(req, res) {
var call = Call.get(req.param('id'));
if (!call) return res.status(404).send('Call not found');
res.json(call.toJSON());
});
// Render call page
router.get('/:id', function(req, res) {
var call = Call.get(req.param('id'));
if (!call) return res.redirect('/new');
res.render('call', {
apiKey: config.peerjs.key,
call: call.toJSON()
});
});
// Landing page
router.get('/', function(req, res) {
res.render('index');
});
module.exports = router;

呼叫.js(html 文件)

<!DOCTYPE html>
<html>
<head>
<title>Rapidcom</title>
</head>
<body>
<div class="wrapper">
<div id="display"></div>
</div>
<footer>
<div class="wrapper">
<a href="/new"> ~~~~~Start another call~~~~~~~</a>
</div>
</footer>
var peer = new Peer( id,{ host: 'https://rapidcom.herokuapp.com', port: 9000, path: '.public/app' });
window.call = <%- JSON.stringify(call, null, 2) %>;

<script src="/app.js"></script>
<script src="/peer.js"></script>

我也在 heroku 上托管了一个 PeerJs 服务器，请帮助我创建这个，我不知道我卡在哪里。我尝试拉动每根绳子，但没有收到这样的错误。

Answer 1

在应用程序中.js而不是

var peer = new Peer({
host: location.hostname,
port: location.port || (location.protocol === 'https://rapidcom.herokuapp.com' ? 9000 : 80),
path: '/peerjs'
});

添加了这个

me = new Peer({　host:'rapidserver.herokuapp.com', secure:true, port:443, key: 'peerjs', debug: 3})
