在Socket IO中找不到类“CI_Controller”

如何解决这个错误？ 目录-application -controller -Rest.php -app.js

app.js

'use strict'; var app = require('express')(); var http = require('http').Server(app); var io = require('socket.io')(http); var phpExpress = require('php-express')({ // assumes php is in your PATH binPath: 'php' }); var path = require('path'); app.set('port',process.env.PORT || 8000); app.set('views','application/controllers'); app.engine('php', phpExpress.engine); app.set('view engine', 'php'); app.use(require('express').static(path.join(__dirname, 'public'))); app.use(require('express').static(path.join(__dirname, 'bower_components'))); app.get('/', function(req, res) { return res.render('rest'); }); io.on('connection', function(socket) { socket.on('chat:pesan', function(pesan) { io.emit('chat:pesan', pesan); }); }); http.listen(app.get('port'), function() { console.log('Server jalan di port ' + app.get('port') + __dirname); }); 

Rest.php

 <?php class Rest extends CI_Controller{ public function __construct(){ parent:: __construct(); date_default_timezone_set("Asia/Jakarta"); $this->load->helper('url'); $this->load->model('rest_model'); $this->load->model('log_model'); $this->load->library('parsing_data'); } } ?> 

结果

致命错误：在第2行的C：\ xampp \ htdocs \ iap \ tugas1 \ application \ controllers \ rest.php中找不到类“CI_Controller”
