我在这些文件中有以下代码:
应用程序.js:
/**
* Module dependencies.
*/
var io = require('socket.io')
, express = require('express')
, mongoose = require('mongoose')
, models = require('./models')(mongoose)
, routes = require('./routes')(models);
var app = module.exports = express.createServer();
// Configuration
app.configure(function(){
app.use(express.cookieParser());
app.use(express.session({secret:'123abc',key:'express.sid'}));
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'));
});
app.configure('development', function(){
app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
});
app.configure('production', function(){
app.use(express.errorHandler());
});
// Routes
app.get('/', routes.index);
var sio = io.listen(app);
app.listen(3000);
sio.sockets.on('connection', function(socket) {
socket.send('this is a test');
console.log('socket connected, sessionID ' + socket.handshake.sessionID);
socket.emit('welcome', {msg: 'welcome'});
});
var parseCookie = require('connect').utils.parseCookie;
sio.set('authorization', function (data, accept) {
if (data.headers.cookie) {
data.cookie = parseCookie(data.headers.cookie);
data.sessionID = data.cookie['express.sid'];
} else {
return accept('No cookie transmitted.', false);
}
accept(null, true);
});
console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env);
/javascripts/socket.js:
var socket = io.connect('http://173.255.229.76', {port:3000});
socket.on('connect', function(data) {
console.log('connected');
});
socket.on('message', function(data) {
console.log(data);
});
socket.on('welcome', function(data) {
console.log(data);
});
布局.jade:
!!!
html
head
title= title
link(rel='stylesheet', href='/stylesheets/style.css')
script(src="/socket.io/socket.io.js")
script(src="/javascripts/socket.js")
body!= body
当客户端连接时,我在控制台中获得调试信息,显示我期望的所有输出,但客户端上没有任何内容。没有任何事件被调用,并且没有数据记录到控制台。我究竟做错了什么?随意访问网址: http: //173.255.229.76 :3000并亲自查看。
