使用socket.io配置Express 4.0路由

I have created a new Express application. It generated app.js for me and I have then created the following index.js bringing in socket.io:

我已经创建了一个新的Express应用程序。它为我生成app.js，然后我创建了以下索引。js引进socket . io:

var app = require('./app');
server=app.listen(3000);

var io = require('socket.io');
var socket = io.listen(server, { log: false });

socket.on('connection', function (client){
    console.log('socket connected!');
});

Can anyone advise how I would access socket.io within the routes files?

任何人都能告诉我如何接入插座。io中的路由文件?

For reference, the default generated app.js is below:

作为参考，默认生成的app.js如下:

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 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');

app.use(favicon());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', routes);
app.use('/users', users);

/// catch 404 and forwarding 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;

SocketIO does not work with routes it works with sockets.

SocketIO对套接字的路由不起作用。

That said you might want to use express-io instead as this specially made for this or if you are building a realtime web app then try using sailsjs which already has socketIO integrated to it.

也就是说，你可能想要使用express-io作为这个特别制作的应用，或者如果你正在构建一个实时web应用，那么尝试使用sailsjs，它已经集成了socketIO。

Do this to your main app.js

把它写在你的主应用程序上。

app = require('express.io')()
app.http().io()

app.listen(7076)

Then on your routes do something like:

然后在你的路线上做一些类似的事情:

app.get('/', function(req, res) {
    // Do normal req and res here
    // Forward to realtime route
    req.io.route('hello')
})

// This realtime route will handle the realtime request
app.io.route('hello', function(req) {
    req.io.broadcast('hello visitor');
})

See the express-io documentation here.

请参阅这里的express-io文档。

Or you can do this if you really want to stick with express + socketio

如果你真的想坚持快递+小把戏，你也可以这么做

On your app.js

在你app.js

server = http.createServer(app)
io = require('socket.io').listen(server)
require('.sockets')(io);

Then create a file sockets.js

然后创建一个文件sockets.js

module.exports = function(io) {

    io.sockets.on('connection', function (socket) {
        socket.on('captain', function(data) {
            console.log(data);
            socket.emit('Hello');
        });
    });
};

You can then call that to your routes/controllers.

然后你可以调用你的路由/控制器。
