Express socket.io强大的意思。坚持如何在forms上进行整合

我正在做一个吝啬的

server.js

'use strict'; /** * Module dependencies. */ var express = require('express'), fs = require('fs'), passport = require('passport'), logger = require('mean-logger'); /** * Main application entry file. * Please note that the order of loading is important. */ //Load configurations //Set the node enviornment variable if not set before process.env.NODE_ENV = process.env.NODE_ENV || 'development'; //Initializing system variables var config = require('./config/config'), auth = require('./config/middlewares/authorization'), mongoose = require('mongoose'); //Use only for development env if (process.env.NODE_ENV === 'development') { //mongoose.set('debug', true); } // set temp directory for uploads process.env.TMPDIR = config.tmp; //Bootstrap db connection var db = mongoose.connect(config.db); //Bootstrap models var modelsPath = __dirname + '/app/models'; var walk = function(path) { fs.readdirSync(path).forEach(function(file) { var newPath = path + '/' + file; var stat = fs.statSync(newPath); if (stat.isFile()) { if (/(.*)\.(js$|coffee$)/.test(file)) { require(newPath); } } else if (stat.isDirectory()) { walk(newPath); } }); }; walk(modelsPath); //bootstrap passport config require('./config/passport')(passport); var app = express() , http = require('http') , server = http.createServer(app) , io = require('socket.io').listen(server); //express settings require('./config/express')(app,passport,db); //Bootstrap routes require('./config/routes')(app,passport,auth); //Start the app by listening on <port> var port = process.env.PORT || config.port; server.listen(port); io.sockets.on('connection', function (socket){ socket.on('addPost', function (data) { socket.broadcast.emit('addedPost', data); }); }); console.log('Express app started on port ' + port); //Initializing logger logger.init(app,passport ,mongoose); //expose app exports = module.exports = app; 

routes.js

 var postController = require('../app/controllers/api/post'); 

应用程序/控制器/ API / post.js

 exports.upload = function(req, res,next) { var w = 200; var h = 75; var form = new formidable.IncomingForm; form.on('progress', function(bytesReceived, bytesExpected){ var percent = Math.floor(bytesReceived / bytesExpected * 100); // here is where you can relay the uploaded percentage using Socket.IO // How can got socket here ! socket.emit('progress', { percent: percent }); }); form.parse(req, function(err, fields, files){ if(err){ res.jsonp(500, err.message); } }); }; 

我不find在出口获得套接字的方式。上传任何想法？
