改进版 —websocket与http共存— to thi tha–

服务

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var g_socket;io.on('connection', function (socket) {
    socket.emit('news', { hello: 'world1--lala' });
    socket.on('my other event', function (data) {
        console.log(data);
    });
    g_socket=socket;
});
// 服务器侦听在sockettest.com的3000端口上
http.listen(3001, function(){
    //# 输出到标准输出
    console.log(':3001');
});var app1 = require('express')();
var http1 = require('http').Server(app1);
app1.get('/1', function(req, res){
    g_socket.emit('news', { hello: '13:55world1--lala' });
});
http1.listen(80, function(){
    //# 输出到标准输出
    console.log(':80');
});
