Socket.io + Express：快速声明错误

Question

我要求：

//app.js Socket IO Test
var app = require('express').createServer(),
redis = require('socket.io/node_modules/redis'),
io = require('socket.io').listen(app);

我的错误：

Warning: express.createServer() is deprecated, express
applications no longer inherit from http.Server,
please use:
  var express = require("express");
  var app = express();

如何修改声明以避免此错误？我知道这种方法现在已经被Express弃用了，只是不确定它需要改为什么......

提前致谢！

只需将var app = require（'express'）。createServer（）替换为：

var express = require("express");
var app = express();
