具有Socket.IO延迟发射数据的NodeJS [英] NodeJS with Socket.IO delay emitting data
问题描述
我正在使用Socket.IO主页（http://socket.io/）中的示例。它的工作原理和一切，但是在发送数据和在另一端收到数据之间存在很大的延迟。
I am using the example from the Socket.IO homepage (http://socket.io/). It works and everything, but there is a huge delay between the time data is sent, and when that data is received on the other end.
我正在使用XAMPP，我在我的目录中有socket.html，并在我的浏览器中使用http：//localhost/socket.html导航到它，我让服务器在端口8080上侦听。
I am using XAMPP, I have socket.html in my dir, and navigate to it using "http://localhost/socket.html" in my browser, and I have the server listening on port 8080.
服务器：
var io = require('socket.io').listen(8080);
io.sockets.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
console.log(data);
});
});
HTML文件：
<html>
<head>
<script src="http://localhost:8080/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost:8080');
socket.on('news', function (data) {
console.log(data);
socket.emit('my other event', { my: 'data' });
});
</script>
</head>
<body>
</body>
</html>
推荐答案
我发现了问题。
在服务器
中我改变了：
In the server I changed:
var io = require('socket.io').listen(8080);
到
var io = require('socket.io', { rememberTransport: false, transports: ['WebSocket', 'Flash Socket', 'AJAX long-polling'] }).listen(8080);
强制服务器使用WebSockets，Flash Sockets或长轮询。它会尝试按顺序使用它们。 rememberTransport强制服务器和客户端忘记它最后使用的连接，并尝试连接上面的'transports'。
which forces the server to use either WebSockets, Flash Sockets, or long-polling. It wil try to use those in that order. The rememberTransport forces the server and client to forget which connection it used last, and try to connect with the 'transports' above.
在客户端我几乎已经做了同一件事情。
我补充说：
On the client side I just pretty much did the same thing. I added:
{ rememberTransport: false, transports: ['WebSocket', 'Flash Socket', 'AJAX long-polling']}
到套接字构造函数。所以它看起来像：
to the socket constructor. So it looked like:
var socket = io.connect('http://localhost:843', { rememberTransport: false, transports: ['WebSocket', 'Flash Socket', 'AJAX long-polling']});
现在看起来效果很好。
谢谢你们。
