利用Node.js对某智能家居服务器重构

var MyClient = function (client, username, password, type){
	this.client = client;
	this.username = username;
	this.password = password;
	this.type = type; //0是机顶盒，1是客户端
}

MyClient.prototype.write = function(msg) {
	this.client.write(msg + ‘\r\n‘);
}

module.exports = MyClient;

//tcp
var net = require(‘net‘);
var crypto = require(‘crypto‘);



var MyClient = require(‘./MyClient‘);

var server = net.createServer();

//客户端，如平台、移动端进来放在这个数组中
var clientArr = [];
//主控端，主要装的是机顶盒的连接
var boxArr = [];


server.on(‘connection‘, function(client){

	
	client.setEncoding(‘utf-8‘);
	client.write(‘plase input name|password|type :\n‘);

	var myClient; 
	var message = ‘‘;
	//发送消息
	client.on(‘data‘, function(data){
		//如果是非回车则累加
		if(‘\r\n‘ != data || data == ‘‘ || data == null) {
			message += data;
		}else {
			//说明是已经注册的client
			if(myClient) {
				sendMsg(message, myClient);
			}else{//说明是第一次进来
				var userInfo = message.split(‘|‘);
				var md5 = crypto.createHash(‘md5‘);
				//使用用户名和密码进行加密，放入password中
				md5.update(userInfo[0] + userInfo[1]);
				var password = md5.digest(‘hex‘);
				myClient = new MyClient(client, userInfo[0], password, +userInfo[2]);
				//如果是客户端
				if(myClient.type) {
					clientArr.push(myClient);
				}else {
					boxArr.push(myClient);
				}
				console.log(‘新加用户‘ + password);
			}
			message = ‘‘;
		}
		
		
		
	})
	//断开时移除这个客户端
	client.on(‘end‘, function(data){
		console.log(‘end....‘);
		//有还未登录就退出的情况
		if(myClient) {
			if(myClient.type) {
				clientArr.splice(clientArr.indexOf(myClient), 1)
			}else {
				boxArr.splice(boxArr.indexOf(myClient), 1)
			}
		}
		
	})
})

server.listen(3000);

function sendMsg(msg, myClient) {
	console.log(‘ sendMsg : ‘ + msg);
	var array = myClient.type == 1 ? boxArr : clientArr;
	for (var i = 0; i < array.length; i++) {
		if (myClient.password == array[i].password) {
			 array[i].write(msg);
			 console.log(myClient.name + myClient.type == 1 ? ‘移动端‘ : ‘主控‘ + ‘发送消息....‘);
		};
	};
}

console.log(‘listening....‘);
