如何解决RTCIceServer.url已弃用！改用urls？

Question

我用soket.io安装了nodejs。 要测试的这款代码到服务器节点server.js

var static = require('node-static'); 
 
var http = require('http'); 
 
// Create a node-static server instance listening on port 8181 
 
var file = new(static.Server)(); 
 
// We use the http module’s createServer function and 
 
// use our instance of node-static to serve the files 
 
var app = http.createServer(function (req, res) { 
 
file.serve(req, res); 
 
}).listen(8181); 
 
// Use socket.io JavaScript library for real-time web applications 
 
var io = require('socket.io').listen(app); 
 
// Let's start managing connections... 
 
io.sockets.on('connection', function (socket){ 
 
// Handle 'message' messages 
 
socket.on('message', function (message) { 
 
log('S --> Got message: ', message); 
 
socket.broadcast.to(message.channel).emit('message', \ 
 
message.message); 
 
}); 
 
// Handle 'create or join' messages 
 
socket.on('create or join', function (channel) { 
 
var numClients = io.sockets.clients(channel).length; 
 
console.log('numclients = ' + numClients); 
 
// First client joining... 
 
if (numClients == 0){ 
 
socket.join(channel); 
 
socket.emit('created', channel); 
 
// Second client joining... 
 
} else if (numClients == 1) { 
 
// Inform initiator... 
 
io.sockets.in(channel).emit('remotePeerJoining', channel); 
 
// Let the new peer join channel 
 
socket.join(channel); 
 
socket.broadcast.to(channel).emit('broadcast: joined', 'S --> \ 
 
broadcast(): client ' + socket.id + ' joined channel ' \ 
 
+ channel); 
 
} else { // max two clients 
 
console.log("Channel full!"); 
 
socket.emit('full', channel); 
 
} 
 
}); 
 
// Handle 'response' messages 
 
socket.on('response', function (response) { 
 
log('S --> Got response: ', response); 
 
// Just forward message to the other peer 
 
socket.broadcast.to(response.channel).emit('response', 
 
response.message); 
 
}); 
 
// Handle 'Bye' messages 
 
socket.on('Bye', function(channel){ 
 
// Notify other peer 
 
socket.broadcast.to(channel).emit('Bye'); 
 
// Close socket from server's side 
 
socket.disconnect(); 
 
}); 
 
// Handle 'Ack' messages 
 
socket.on('Ack', function() { 
 
console.log('Got an Ack!'); 
 
// Close socket from server's side 
 
socket.disconnect(); 
 
}); 
 
// Utility function used for remote logging 
 
function log(){ 
 
var array = [">>> "]; 
 
for (var i = 0; i < arguments.length; i++) { 
 
array.push(arguments[i]); 
 
} 
 
socket.emit('log', array); 
 
} 
 
});

和client.js

<script> 
 
// Get <div> placeholder element from DOM 
 
div = document.getElementById('scratchPad'); 
 
// Connect to server 
 
var socket = io.connect(); 
 
// Ask channel name from user 
 
channel = prompt("Enter signaling channel name:"); 
 
if (channel !== "") { 
 
console.log('Trying to create or join channel: ', channel); 
 
// Send 'create or join' to the server 
 
socket.emit('create or join', channel); 
 
} 
 
// Handle 'created' message 
 
socket.on('created', function (channel){ 
 
console.log('channel ' + channel + ' has been created!'); 
 
console.log('This peer is the initiator...'); 
 
// Dynamically modify the HTML5 page 
 
div.insertAdjacentHTML('beforeEnd', '<p>Time: ' +(performance.now()/1000).toFixed(3) + ' --> Channel '+ channel + ' has been created! </p>'); 
 
div.insertAdjacentHTML('beforeEnd', '<p>Time: ' +(performance.now()/1000).toFixed(3) +' --> This peer is the initiator...</p>'); 
 
}); 
 
// Handle 'full' message 
 
socket.on('full', function (channel){console.log('channel ' + channel + ' is too crowded! Cannot allow you to enter, sorry :-('); 
 
div.insertAdjacentHTML('beforeEnd', '<p>Time: ' +(performance.now()/1000).toFixed(3) + ' --> channel ' + channel + ' is too crowded! Cannot allow you to enter sorry :-(</p>'); 
 
}); 
 
// Handle 'remotePeerJoining' message 
 
socket.on('remotePeerJoining', function (channel){ 
 
console.log('Request to join ' + channel); 
 
console.log('You are the initiator!'); 
 
div.insertAdjacentHTML('beforeEnd', '<p style="color:red">Time: ' +(performance.now()/1000).toFixed(3) +' --> Message from server: request to join channel ' +channel + '</p>');

console.log('Broadcast message from server: ' + msg); 
 
// Start chatting with remote peer: 
 
// 1. Get user's message 
 
var myMessage = prompt('Insert message to be sent to your peer:', ""); 
 
// 2. Send to remote peer (through server) 
 
socket.emit('message', { 
 
channel: channel, 
 
message: myMessage}); 
 
}); 
 
// Handle remote logging message from server 
 
socket.on('log', function (array){ 
 
console.log.apply(console, array); 
 
}); 
 
// Handle 'message' message 
 
socket.on('message', function (message){

console.log('Going to disconnect...'); 
 
socket.disconnect(); 
 
});

但是当我做节点服务器。 js提示我有这个错误

，我获取Firefox

RTCIceServer.url已经过时！改为使用网址。

如何解决？

Answer 1

（我正在回答你的问题，因为你的问题的其余部分似乎不相关）。

Firefox Web控制台警告引用您的RTCPeerConnection配置。

找到类似下面的代码：

var pc = new RTCPeerConnection({ iceServers: [{ url: 'stun:foo.com:1234' }] }); 

，重命名为：

var pc = new RTCPeerConnection({ iceServers: [{ urls: 'stun:foo.com:1234' }] }); 
               ^

名字改了，因为每个冰服务器实际上可能有多种方式（网址），它可以位于，取决于网络拓扑。
