正如标题中所述,我尝试使用带有Express 4.2的socket.io 1.0.4,并且所有/?EIO
个请求都返回404。
贝娄有我的档案:
./ bin / www:
#!/usr/bin/env node
var debug = require('debug')('generated-express-app');
var app = require('../app');
app.set('port', process.env.PORT || 3000);
var server = app.listen(app.get('port'), function() {
debug('Express server listening on port ' + server.address().port);
});
./ app.js:
var express = require('express');
var path = require('path');
var favicon = require('static-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var app = express();
// Extras para Socket.io
// var server = require('http').Server(app);
// var io = require('socket.io')(server);
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(favicon());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
app.use(cookieParser());
app.use(require('less-middleware')(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));
// Requests
app.get('/', function (req, res) {
res.render('index', { title: 'Express' });
});
// Socket requests
//
//io.on('connection', function (socket) {
// socket.emit('news', { hello: 'world' });
// socket.on('my other event', function (data) {
// console.log(data);
// });
//});
/// 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;
var server = require('http').createServer(app);
server.listen(app.get('port'), function(){
console.log('Express listening on port ' + app.get('port'));
});
var io = require('socket.io').listen(server);
io.sockets.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
console.log(data);
});
});

我更多地使用我的文件,并让它工作,这是我如何工作:
./ bin / www:需要保留要求 app.js ,否则无法正常工作。
#!/usr/bin/env node
//var debug = require('debug')('generated-express-app');
var app = require('../app');
//app.set('port', process.env.PORT || 3000);
//
//var server = app.listen(app.get('port'), function() {
// debug('Express server listening on port ' + server.address().port);
//});
//
//var io = require('socket.io').listen(server);
//
//io.sockets.on('connection', function (socket) {
// socket.emit('news', { hello: 'world' });
// socket.on('my other event', function (data) {
// console.log(data);
// });
//});
./ app.js: www 上的所有信息都会在上次导出之前发送到此处。

});
var io = require('socket.io').listen(server);
io.sockets.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
console.log(data);
});
});
module.exports = app;
我使用快速生成器生成项目,禁用了路由,因为Socket.io似乎不支持快速路由。

所以,一年之后,以及更多的节点研究后来,我发现之前的答案相当不完整,可能会导致表达式的次优使用。这是使用Node + Express + Socket.io而没有问题的更正确的方法:
在 /bin/www.js 上,将var http = require('http');
替换为var server = require('http').Server(app);
,然后移除var server = http.createServer(app);
就是这样......正常使用您的路线,在任何地方进行聊天,不再有任何问题。
