如何从socket.io 1.2迁移到socket.io 0.9.16？

Question

我有这样的代码写在Socket.io 1.2

var app=require('express')(); 
var http=require('http').Server(app); 
var io=require('socket.io')(http); 
var room; 
var messageEmitted;; 
app.get('/', function(req, res){ 
    res.sendFile(__dirname +'/index.html'); 
}); 
app.get('/lol', function(req, res){ 
    res.sendFile(__dirname +'/lol.html'); 
}); 
io.use(function(socket,next){ 
    var handShakeData=socket.request; 
    room=handShakeData._query['roomName']; 
    messageEmitted=handShakeData._query['messageText']; 
    next(); 
}); 

io.on('connection',function(socket){ 
    console.log('A user connnected on : '+room); 
    socket.join(room); 
    io.to(room).emit('emittedMessages',messageEmitted); 
    console.log(messageEmitted); 
    /*socket.on('emittedMessages',function(msg){ 
     //socket.emit(msg); // Send message to sender 
     socket.broadcast.emit(msg); // Send message to everyone BUT sender 
    });*/ 
    socket.on('disconnect', function(){ 
     // io.to(room).emit('emittedMessages','A User Disconnected on: '+room); 
     console.log('A user disconnected'); 
    });  
}); 


http.listen(3000,function(){ 
    console.log('Listening oon Port: 3000'); 
}); 

而这个代码工作完全正常。

我试图访问来自Android库里这个代码调用Gottox这个版本需要0.9.16

然而，当我试图通过键入以下命令移动到旧库即0.9.16：

npm remove socket.io

npm install socket.io@0.9.16

当我运行：

node server.js

我得到这个错误：

D:\NodeJSSocketBroadcast>node server.js 

D:\NodeJSSocketBroadcast\server.js:3 
var io=require('socket.io')(http); 
         ^
TypeError: object is not a function 
    at Object.<anonymous> (D:\NodeJSSocketBroadcast\server.js:3:28)

    at Function.Module.runMain (module.js:497:10) 
    at startup (node.js:119:16) 
    at node.js:906:3 

如何在老版本的socket.io中实现相同的功能？我找不到任何文件。我也发现this link描述相同。

请帮忙。 :(:(

Answer 1

const server = require('http').createServer(); 
var io = require('socket.io').listen(server); 
server.listen(1337);` 

但我建议使用https://github.com/nkzawa/socket.io-client.java - Java实现支持socket.io 1.2.1
