如何将包含NodeJs模块的Codeigniter应用程序部署到Bluemix？
我目前正在使用一些nodejs来处理一些实时特性的codeigniter应用程序，我使用socket.io和express来集成nodejs模块来开发一个实时聊天应用程序。 我试图将我的应用程序部署到我的codeigniter应用程序的PHP构buildbluemix，我创build了一个nodejs应用程序来托pipe我的nodejs服务器。 问题是我似乎无法连接到使用io.connect（）的nodejs服务器套接字。 有没有办法做到这一点，而不必在代码中做一些重大的改变。 谢谢。
/*eslint-env node*/ //------------------------------------------------------------------------------ // node.js starter application for Bluemix //------------------------------------------------------------------------------ // This application uses express as its web server // for more info, see: http://expressjs.com var express = require('express'); //var socket = require('socket.io'); // cfenv provides access to your Cloud Foundry environment // for more info, see: https://www.npmjs.com/package/cfenv var cfenv = require('cfenv'); // create a new express server var app = express(); var http = require('http').Server(app); var io = require('socket.io').listen(http); // serve the files out of ./public as our main files app.use(express.static(__dirname + '/')); var people = []; var left = []; var connetcted = false; io.on('connection', function (client) { console.log("New client !"); console.log("socket.id", client.id); client.on('message', function (data) { console.log('Message received ' + data.name + ":" + data.message); //client.broadcast.emit( 'message', { name: data.name, message: data.message } ); io.emit('message', {name: data.name, message: data.message, to: data.to}); }); client.on('connected', function (data) { console.log('Message received ' + data); people[data.current] = data; connetcted = true; delete left[data.current]; //client.broadcast.emit( 'message', { name: data.name, message: data.message } ); io.emit('connected', {current: data.current, people: people}); client.on('disconnect', function () { connetcted = false; setTimeout(function () { if (connetcted === false) { left[data.current] = data; delete people[data.current]; io.emit('deconnexion', {current: data.current, left: left}); } }, 10000); }); }); client.on('notification_client', function (data) { console.log('Message received ' + data.name + ":" + data.id_client); //client.broadcast.emit( 'message', { name: data.name, message: data.message } ); io.emit('notification_client', {message: data.message, id_client: data.id_client}); }); client.on('notification', function (data) { console.log('notification received ' + data.event_id); //client.broadcast.emit( 'message', { name: data.name, message: data.message } ); io.emit('notification', {message: data.message, event_id: data.event_id, id_tenant: data.id_tenant}); //Pushbots.setMessage(data.message, 1); //Pushbots.customFields({"event_id": data.event_id}); //Pushbots.customNotificationTitle("CUSTOM TITLE"); //var token = "APA91bGaZBXL9yv-Gr__0TLju-eMP42oKNPJhTtPocf8ar3OLC736tvi26lcXATDnGw7Ode1B2ONcusTvAP7s2L_06jMo8PIQ1QgmRf9k_EBmn-BqWaZLSK026ZQLWUyoIjArgHF6ssP"; //Pushbots.pushOne(token, function (response) { // console.log(response); //}); }); }); // get the app environment from Cloud Foundry var appEnv = cfenv.getAppEnv(); // start server on the specified port and binding host app.listen(appEnv.port, '0.0.0.0', function() { // print a message when the server starts listening console.log("server starting on " + appEnv.url); }); 基于https://github.com/rauchg/chat-example我能够得到以下应用程序在Bluemix工作。 这似乎可能是调用http.listen()与app.listen() ：
index.js
var app = require('express')(); var http = require('http').Server(app); var io = require('socket.io')(http); app.get('/', function(req, res){ res.sendFile(__dirname + '/index.html'); }); io.on('connection', function(socket){ socket.on('chat message', function(msg){ io.emit('chat message', msg); }); }); http.listen(process.env.PORT, function(){ console.log('listening...'); });
