Socket.io和MEAN.io

Question

我正在尝试通过socket.io在前端angularjs和后端节点之间进行通信。应用程序建立在Mean.io锅炉板上。套接字无法连接到后端。 这是我的代码

Angular.js

  <script src="/socket.io/socket.io.js"></script>
<script>
    var socket = io('localhost:3000');
    console.log('-------->' , socket)

    socket.emit('new', { data: 'asd' });
    socket.on('hi',  function (data) {
        alert('socket connected     hi called');
        console.log('===================== ============== data',data);
    });
    socket.on('broadcast',  function (data) {
        console.log('===================== ============== data',data);
    });



</script>

Node.js的

MeanStarter.register(function (app, users, system, database, http) {
   var io = require('./server/config/socketio')(http);
   io.on('connection', function (socket) {
   console.log(chalk.orange('------------------------ > a user connected'));
   socket.emit('hi', { data: 'hello' });    
   socket.on('new', function (data) {
      console.log(chalk.orange('=======> hello'));
      })
    });
  app.set('views', path.join(__dirname, '/server/views'))
  MeanStarter.routes(app, database);
  MeanStarter.angularDependencies(['mean.system', 'mean.users', 
  'ui.bootstrap','ngFileUpload', 'angularjs-dropdown-multiselect', 
  'angularMoment','mwl.calendar'])
  return MeanStarter
 })

./服务器/配置/ socketio

  'use strict';
    var config = require('meanio').loadConfig(),
     cookie = require('cookie'),
     cookieParser = require('cookie-parser'),
     socketio = require('socket.io'),
     chalk = require('chalk');
     module.exports = function(http) {   
     var io = socketio.listen(http);
    //  console.log( chalk.green('Socket Io conf',io));
     io.use(function(socket, next) {
        var data = socket.request;
        if (!data.headers.cookie) {
            return next(new Error('No cookie transmitted.'));
        }
        var parsedCookie = cookie.parse(data.headers.cookie);
        var sessionID = parsedCookie[config.sessionName];
        var parsedSessionID = 
              cookieParser.signedCookie(parsedCookie[config.sessionName], 
              config.sessionSecret);
        if (sessionID === parsedSessionID) {
            return next(new Error('Cookie is invalid.'));
        }
       console.log( chalk.green('Socket Io conf'));
        next();
      });

    return io;
    };
