我用 soket.io 安装了 nodejs。 想测试这段代码到服务器 Node 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);

我得到了 firefox
RTCIceServer.url 已弃用!请改用网址。
如何解决?
最佳答案
(我正在回答你的问题,因为你的问题的其余部分似乎无关)。
Firefox Web 控制台警告 "RTCIceServer.url is deprecated! Use urls instead"
指的是您的 RTCPeerConnection 配置。
找到类似这样的代码:
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,因为每个 ice 服务器实际上可能有多种方式(URL)可以定位它,具体取决于网络拓扑。
