簡單的快遞和插座示例不起作用

服務器運行時，套接字不起作用。

控制檯不打印'用戶連接'。

客戶端按鈕不起作用。

請幫幫我。 :-(

這是我的代碼

app.js

var express = require('express'); 
var path = require('path'); 
var favicon = require('serve-favicon'); 
var logger = require('morgan'); 
var cookieParser = require('cookie-parser'); 
var bodyParser = require('body-parser'); 

var routes = require('./routes/index'); 
var users = require('./routes/users'); 

var app = express(); 

// view engine setup 
app.set('views', path.join(__dirname, 'views')); 
app.set('view engine', 'jade'); 

// uncomment after placing your favicon in /public 
//app.use(favicon(__dirname + '/public/favicon.ico')); 
app.use(logger('dev')); 
app.use(bodyParser.json()); 
app.use(bodyParser.urlencoded({ extended: false })); 
app.use(cookieParser()); 
app.use(express.static(path.join(__dirname, 'public'))); 

app.get('/', function(req, res) { 
res.sendFile(__dirname + '/index.html'); 
}); 

// catch 404 and forward to error handler 
app.use(function(req, res, next) { 
    var err = new Error('Not Found'); 
    err.status = 404; 
    next(err); 
}); 

// error handlers 

// development error handler 
// will print stacktrace 
if (app.get('env') === 'development') { 
    app.use(function(err, req, res, next) { 
    res.status(err.status || 500); 
    res.render('error', { 
     message: err.message, 
     error: err 
    }); 
    }); 
} 

// production error handler 
// no stacktraces leaked to user 
app.use(function(err, req, res, next) { 
    res.status(err.status || 500); 
    res.render('error', { 
    message: err.message, 
    error: {} 
    }); 
}); 

module.exports = app;

io.js

var io = require('socket.io')(); 

io.on('connection', function(socket) { 
console.log('user connected'); 
socket.on('rint', function(data) { 
    console.log('user send data : ' + data); 
    socket.emit('smart', data); 
}); 
}); 

module.exports = io;

/斌/ WWW

\#!/usr/bin/env node 

/** 
* Module dependencies. 
*/ 

var app = require('../app'); 
var io = require('../io'); 
var debug = require('debug')('socketT:server'); 
var http = require('http'); 

/** 
* Get port from environment and store in Express. 
*/ 

var port = normalizePort(process.env.PORT || '3000'); 
app.set('port', port); 

/** 
* Create HTTP server. 
*/ 

var server = http.createServer(app); 
io.attach(server); 

/** 
* Listen on provided port, on all network interfaces. 
*/ 

server.listen(port); 
server.on('error', onError); 
server.on('listening', onListening);

的index.html

<!DOCTYPE html> 
<html> 
<head> 
<script src="/socket.io/socket.io.js"></script> 
<script> 
    window.onload = function() { 
    var socket = io(); 
    socket.on('smart', function(data) { 
    alert(data); 
    }); 
    document.getElementById('button').onclick = function() { 
    var text = document.getElementById('text').value; 
    socket.emit('rint', text); 
    }); 
    }); 
</script> 
</head> 
<body> 
<input type="text" id="text" /> 
<input type="button" id="button" value="echo" /> 
</body> 
</html>

您對服務器端的一切監聽器上（「連接」，...但你不要讓任何地方的客戶端該連接。

檢查以下網頁：http://socket.io/docs/

您將需要添加服務器的URL要連接：

的index.html：

var socket = io("localhost:8080"); //Or whatever your url and port are.
