Question

我使用node.js和socket io

创建了一个用于通信的小型服务器

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>

沟通不会发生，我在这里做错了吗？

如果您的服务器正在侦听端口8888，则需要客户端通过端口8888连接到服务器。

客户端代码中的以下行：

var socket = io.connect('http://localhost/namespace');

应阅读：

 var socket = io.connect('http://localhost:8888/namespace');

node.js和socket.io
