如何解决不建议使用RTCIceServer.url！使用网址代替？
我用soket.io安装了nodejs。想要将此代码测试到服务器节点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>');

div.insertAdjacentHTML( 'beforeEnd', '<p style="color:red">' +msg + '</p>');
console.log('Broadcast message from server: ' + msg);
// Start chatting with remote peer:

var myMessage = prompt('Insert message to be sent to your peer:', "");

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

}else{

我得到了Firefox
不建议使用RTCIceServer.url！请改用网址。
怎么解决 ？
回答：
（我正在回答您的主题，因为其余的问题似乎无关紧要）。
Firefox Web控制台警告"RTCIceServer.url is deprecated! Use urls
instead"是指您的RTCPeerConnection配置。
找到类似于以下代码：
var pc = new RTCPeerConnection({ iceServers: [{ url: 'stun:foo.com:1234' }] });并将其重命名为：
var pc = new RTCPeerConnection({ iceServers: [{ urls: 'stun:foo.com:1234' }] }); ^
名称已更改，因为根据网络拓扑，每个冰服务器实际上可能有多种可以定位的方式（URL）。
