I’m using NodeJS v0.4.8 and the latest Version of socket.io from

我正在使用NodeJS v0.4.8和最新版本的socket.io

npm install socket.io

npm install socket.io

on Ubuntu:

Linux mars 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU/Linux

Linux mars 2.6.38-8-generic#42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU / Linux

The following code unfortunately doesn't produce any output, wheter on client, nor on server side.

遗憾的是,以下代码不会在客户端或服务器端产生任何输出。

Does anybody have a clue?

有人有线索吗?

SERVER-SIDE

var http = require('http'),  
io = require('socket.io'),
fs = require('fs'),
sys = require('sys');

respcont = fs.readFileSync('testclient.js');

server = http.createServer(function(req, res){
    res.writeHead(200, {'Content-Type': 'text/html'}); 
    res.end(respcont);
});
server.listen(8082);

var socket = io.listen(server); 
socket.on('connection', function(client){ 

    sys.puts("New client is here!");
    client.send("hello world");

    client.on('message', function(msg) { sys.puts("client has sent:"+msg); }) ;
    client.on('disconnect', function() { sys.puts("Client has disconnected"); }) ;
});

CLIENT-SIDE

<html>
<body>
<script type="text/javascript" src="http://localhost:8082/socket.io/socket.io.js"></script>
<script> 
    var socket = new io.Socket(null,{port:8082,rememberTransport:true,timeout:1500});
    socket.connect();
    socket.on('connect', function() { 
        console.log('connected to server'); 
        socket.send('Hi Server...'); 
    });

    socket.on('message', function() { 
        console.log('received a message!');
    });

    socket.on('disconnect', function() { 
        console.log('disconnected from server'); 
    });

</script> 
</body>
</html>

The output from NodeJS (NOT the sys.puts("...") calls) is:

NodeJS的输出(不是sys.puts(“...”)调用)是:

info - socket.io started debug - served static /socket.io.js debug - client authorized info - handshake authorized info - handshaken b61a5c2751c1c8c8493db4b79d19e779

info - socket.io启动调试 - 服务静态/socket.io.js调试 - 客户端授权信息 - 握手授权信息 - handshaken b61a5c2751c1c8c8493db4b79d19e779

I also(like Derrish) like to use express framework to simplify my work(AWESOME :)). You can download and extract this sample from http://dl.dropbox.com/u/314941/socketio.zip. I believe you don't even have to install these modules because I have bundled them locally(just run) thanks to npm :).

我也(像Derrish)喜欢使用快速框架来简化我的工作(AWESOME :))。您可以从http://dl.dropbox.com/u/314941/socketio.zip下载并提取此示例。我相信你甚至不必安装这些模块,因为我已经将它们捆绑在本地(只是运行),这要归功于npm :)。

After 2 seconds it will display Waited two seconds!

I took your example and dropped it in an a node app using express. Your HTML code was placed in a static HTML file under public. Your example worked fine. The code is shown below. I wanted to make sure both the socket.io script file and the HTML file were being served up properly.

我拿了你的例子并使用express将它放在一个节点应用程序中。您的HTML代码放在公共的静态HTML文件中。你的例子工作正常。代码如下所示。我想确保正确提供socket.io脚本文件和HTML文件。

var http = require('http'),  
    io = require('socket.io'),
    express = require('express');

var app = module.exports = express.createServer();

// Configuration

app.configure(function(){
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

if (!module.parent) {
  app.listen(9000);
  console.log("server started at %s", (new Date()).toUTCString());
  console.log("listening on port %d", app.address().port);
}


// socket.io 
var socket = io.listen(app); 
socket.on('connection', function(client){ 
    console.log("New client is here!");
    client.send("hello world");
    client.on('message', function(msg){ console.log("client has sent:"+msg); }) ;
    client.on('disconnect', function(){ console.log("Client has disconnected"); }) ;
    client.on('disconnect', function(){ })
