我正在尝试这个简单的socket.io示例,它可以在Safari中工作(从双方发送/接收)。但是,在Chrome中,客户端会收到消息,但服务器不会接收客户端发送的消息
的index.html
<!doctype html>
<html>
<head>
<title>web sockets</title>
<meta charset="utf-8">
<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost:8888');
socket.on('news', function (data) {
console.log(data);
writeMessage(data);
socket.emit('my other event', { my: 'data' });
});
function writeMessage(msg) {
var msgArea = document.getElementById("msgArea");
if (typeof msg == "object") {
msgArea.innerHTML = msg.hello;
}
else {
msgArea.innerHTML = msg;
}
}
</script>
</head>
<body>
<div id="msgArea">
</div>
</body>
</html>
server.js
var app = require('http').createServer(handler)
, io = require('/usr/local/lib/node_modules/socket.io').listen(app)
, fs = require('fs')
app.listen(8888);
function handler (req, res) {
fs.readFile(__dirname + '/index.html',
function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Error loading index.html');
}
res.writeHead(200);
res.end(data);
});
}
io.sockets.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
console.log(data);
});
});
我错过了什么吗? Chrome已发布第19页
