Node.js 和 socket.io
我创建了一个小型服务器，用于使用 node.js 和套接字 io 进行通信
服务器：
var express = require('/usr/local/lib/node_modules/express')
var io = require('/usr/local/lib/node_modules/socket.io');
var server = express.createServer();
server.listen(8888,'localhost');
io = io.listen(server);
io.of("namespace").on('connection', function(client){
client.emit("message",'connection successful');
client.on('message', function(m){
console.log("received message"+m);
client.broadcast(m);
});
});
客户端：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Comet Test</title>
<script src="http://localhost:8888/socket.io/socket.io.js" type="text/javascript"></script>
</head>
<body>
<p><a id='customAlert' href="#" onclick='sendMessage("customAlert")'>publish customAlert</a></p>
<p><a id='customAlert2' href="#" onclick='sendMessage("customAlert2")'>publish customAl
<script type="text/javascript">
// Start the socket
var socket = io.connect('http://localhost:8888/namespace');
socket.on('error', function (reason){
console.error('Unable to connect Socket.IO', reason);
});
socket.on('message', function(msg){
console.log(msg);
});
function sendMessage(m) {
console.log("sending message"+m);
socket.emit("message",m);
}
</script>
</body>
沟通没有发生，我在这里做错了什么吗？
I have created a small server for communication using node.js and socket io
Server:
var express = require('/usr/local/lib/node_modules/express')
var io = require('/usr/local/lib/node_modules/socket.io');
var server = express.createServer();
server.listen(8888,'localhost');
io = io.listen(server);
io.of("namespace").on('connection', function(client){
client.emit("message",'connection successful');
client.on('message', function(m){
console.log("received message"+m);
client.broadcast(m);
});
});
Client:
<html>

<script src="http://localhost:8888/socket.io/socket.io.js" type="text/javascript"></script>

var socket = io.connect('http://localhost:8888/namespace');
socket.on('error', function (reason){
console.error('Unable to connect Socket.IO', reason);
});
socket.on('message', function(msg){
console.log(msg);
});
function sendMessage(m) {
console.log("sending message"+m);
socket.emit("message",m);
}
</script>
</body>
Communication does not happen, am I doing something wrong here?

如果您的服务器正在侦听端口 8888，则需要客户端连接到端口 8888 上的服务器。
客户端代码中的以下行：
应读取：
If your server is listening on port 8888, you need the client to connect to the server on port 8888.
The following line in your client code:
