这是我的app.js

＆＃13;

var React         = require('react');
var Router        = require('react-router');
var RouteHandler  = Router.RouteHandler;
var Header        = require('./parts/Header');
var io = require('socket.io-client');
var APP = React.createClass({

  getInitialState(){
    return {
      status  : 'disconnected',
      title   : '',
      member  : {},
      audience: [],
      speaker : '',
      questions: [],
      currentQuestion: false
    }
  },

  componentWillMount(){
    this.socket = io('react-test.derrickmv.com');
    this.socket.on('connect', this.connect);
    this.socket.on('disconnect', this.disconnect);
    this.socket.on('welcome', this.updateState);
    this.socket.on('joined', this.joined);
    this.socket.on('audience', this.updateAudience);
    this.socket.on('start', this.start);
    this.socket.on('end', this.updateState);
    this.socket.on('ask', this.ask);
  },

  emit(eventName, payload){
    this.socket.emit(eventName, payload);
  },

  connect(){
    var member = (sessionStorage.member) ? JSON.parse(sessionStorage.member): null;

    if (member && member.type ==='audience'){
      this.emit('join', member);
    } else if (member && member.type === 'speaker'){
      this.emit('start', {name: member.name, title : sessionStorage.title});
    }

    this.setState({ status: 'connected'});
  },

  disconnect(){
    this.setState({
      status: 'disconnected',
      title:   'disconnected',
      speaker: ''
    });
  },

  updateState(serverState){
    this.setState(serverState);
  },

  joined(member){
     sessionStorage.member = JSON.stringify(member);
     this.setState({ member: member});
  },

  start(presentation){
     if( this.state.member.type === 'speaker'){
       sessionStorage.title = presentation.title;
     }
     this.setState(presentation);
  },

  ask(question){
    sessionStorage.answer = '';
    this.setState({ currentQuestion: question });
  },

  updateAudience(newAudience){
    this.setState({ audience: newAudience});
  },

  render(){
    return (
      <div>
          <Header {...this.state} />
          <RouteHandler emit={this.emit} {...this.state} />
      </div>
    );
  }
});

module.exports = APP;

＆＃13;

将所有内容放入我的服务器后，我在控制台日志中收到以下错误，说明404（未找到）错误。

这是我的app-server.js：

非常感谢您的帮助！

尝试用node.js实现socket.io表达并对我的生产服务器做出反应
