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>');

});

// Handle 'joined' message

socket.on('joined', function (msg){

console.log('Message from server: ' + msg);div.insertAdjacentHTML( 'beforeEnd', '<p>Time: ' +(performance.now() / 1000).toFixed(3) +' --> Message from server: </p>');

div.insertAdjacentHTML( 'beforeEnd', '<p style="color:blue">' +msg + '</p>');

div.insertAdjacentHTML( 'beforeEnd', '<p>Time: ' +(performance.now() / 1000).toFixed(3) +' --> Message from server: </p>');

div.insertAdjacentHTML( 'beforeEnd', '<p style="color:blue">' +msg + '</p>');

});

// Handle 'broadcast: joined' message

socket.on('broadcast: joined', function (msg){

div.insertAdjacentHTML( 'beforeEnd', '<p style="color:red">Time: ' +(performance.now() / 1000).toFixed(3) +' --> Broadcast message from server: </p>');

div.insertAdjacentHTML( 'beforeEnd', '<p style="color:red">' +msg + '</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('Got message from other peer: ' + message);

div.insertAdjacentHTML( 'beforeEnd', '<p>Time: ' +(performance.now() / 1000).toFixed(3) +' --> Got message from other peer: </p>');

div.insertAdjacentHTML( 'beforeEnd', '<p style="color:blue">' +message + '</p>');

// Send back response message:

// 1. Get response from user

var myResponse = prompt('Send response to other peer:', "");

// 2. Send it to remote peer (through server)

socket.emit('response', {

channel: channel,

message: myResponse});

});

// Handle 'response' message

socket.on('response', function (response){

console.log('Got response from other peer: ' + response);

div.insertAdjacentHTML( 'beforeEnd', '<p>Time: ' +(performance.now() / 1000).toFixed(3) +' --> Got response from other peer: </p>');

div.insertAdjacentHTML( 'beforeEnd', '<p style="color:blue">' +response + '</p>');

// Keep on chatting

var chatMessage = prompt('Keep on chatting. Write "Bye" to quit conversation', "");

// User wants to quit conversation: send 'Bye' to remote party

if(chatMessage == "Bye"){

div.insertAdjacentHTML( 'beforeEnd', '<p>Time: ' +(performance.now() / 1000).toFixed(3) +' --> Sending "Bye" to server...</p>');

console.log('Sending "Bye" to server');

socket.emit('Bye', channel);

div.insertAdjacentHTML( 'beforeEnd', '<p>Time: ' +(performance.now() / 1000).toFixed(3) +' --> Going to disconnect...</p>');

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

// Disconnect from server

socket.disconnect();

}else{

// Keep on going: send response back

// to remote party (through server)

socket.emit('response', {

channel: channel,

message: chatMessage});

}

});

// Handle 'Bye' message

socket.on('Bye', function (){

console.log('Got "Bye" from other peer! Going to disconnect...');

div.insertAdjacentHTML( 'beforeEnd', '<p>Time: ' +(performance.now() / 1000).toFixed(3) +' --> Got "Bye" from other peer!</p>');

div.insertAdjacentHTML( 'beforeEnd', '<p>Time: ' +(performance.now() / 1000).toFixed(3) +' --> Sending "Ack" to server</p>');

// Send 'Ack' back to remote party (through server)

console.log('Sending "Ack" to server');

socket.emit('Ack');

// Disconnect from server

div.insertAdjacentHTML( 'beforeEnd', '<p>Time: ' +(performance.now() / 1000).toFixed(3)+' --> Going to disconnect...</p>');

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

socket.disconnect();

});

但是当我执行node server.js提示时出现此错误

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)。
