我是 node.js 和 socket.io 的新手,并尝试使用http://socket.io/#how-to-use中的示例将服务器连接到客户端。(没有本地主机)
服务器:
var app = require('http').createServer(handler)
, io = require('socket.io').listen(app)
, fs = require('fs')
app.listen(80);
function handler (req, res) {
fs.readFile(__dirname + '/index.html',
function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Error loading index.html'+err);
}
res.writeHead(200);
res.end(data);
});
}
io.sockets.on('connection', function (socket) {
socket.on('message', function(msg){
console.log('Got text: '+msg);
socket.broadcast.send(msg);
});
socket.on('disconnect', function () { });
});
客户:
<html><head><script src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect();
socket.on('connect', function () {
alert('connected.');
socket.on('message', function (msg) {
// my msg
alert('message received: '+msg);
});
socket.send('hi');
});
</script>
</head><body>This is the content :)</body>
</html>
谷歌浏览器在控制台中显示:
Unexpected response code: 502
此外,在收到每条消息后,Chrome 会添加
GET http://[myServer]/socket.io/1/?t=1352313105809 socket.io.js:1659
Socket.handshake socket.io.js:1659
Socket.connect socket.io.js:1699
maybeReconnect
到控制台。问题出在哪里?
