如何在windows系统中安装websocket模块

Answer 1

用socket.io这个模块，可以轻松部署websocket服务
//引入Socket.IO模块，如果此处出错，请确认Socket.IO已安装，
//而且Socket.IO在环境变量NODE_PATH目录中
var io = require(‘socket.io’);
//创建WebSockets服务
var socket = io.listen(server, {
log:true
});
var club = [‘Real Madrid’,‘Barcelona’,‘Manchester United’];
var star = [‘Ronaldo’,‘Messi’,‘Rooney’];
//添加监听，相应前台请求
socket.sockets.on(‘connection’, function(client){
//接收客户端的注册消息
client.on(‘regGetMessage’, function(){
//定时每3秒向客户端发消息,共发3次
var count = 0;
var intervalId;
intervalId = setInterval(function(){
if(count >= 3){
clearInterval(intervalId);
return false;
}
var result = {
SoccerClub: [
{
id: count,
name: club[count]
}
],
SoccerStar: [
{
id: count,
name: star[count]
}
]
};
client.emit(‘getMessage’, result);
count++;
}, 3000);
});
});
