Socket.io文字直播聊天室的简单代码

直接上代码吧,被注释掉的主要是调试代码，和技术选型的测试代码

var app = require('express')();
var server = require('http').Server(app);

server.listen(8080);

app.get('/', function (req, res) {
  res.sendFile(__dirname + '/index.html');
});


var io = require('socket.io')(3000);
var beijing = io
  .of('/beijing')
  .on('connection', function (socket) {
    console.log("beijing connected")
    //console.log(socket)
    socket.on('disconnect', function () { console.log("disconnect") });
    //socket.emit('item', { news: 'item' });
  });
//var redis = require('socket.io-redis');
//io.adapter(redis({ host: '192.168.20.16', port: 6379 }));

//var io_emitter = require('socket.io-emitter')({ host: '192.168.20.16', port: 6379 });
/*setInterval(function(){
  //io_emitter.emit('time', new Date);
}, 2000);*/

var redis = require('redis')
subcriber = redis.createClient("redis://:redispassword@192.168.1.1:6379/0")
subcriber.on("message",function(channel,message){
  console.log(message);
  beijing.emit("message",message);
})

subcriber.subscribe("pub_comments")
/*
var SSE = require('sse-nodejs');

var express = require('express');

var app = express();

app.get('/', function (req,res) {
   res.sendFile(__dirname+ '/index.html')
});

app.get('/time', function (req,res) {
    var serverSent = SSE(res);

    serverSent.sendEvent('time', function () {
        return new Date
    },1000);
    serverSent.disconnect(function () {
        console.log("disconnected");
    })

    //serverSent.removeEvent('time',2000);

});

app.listen(3333);
*/

前端核心代码：

 

var socket = io.connect('http://servername:3000/beijing');
socket.on('message', function (data) {
  $scope.messages.push(data)//此处使用了angularjs
  $scope.$apply()
  console.log(data)
  //socket.disconnect()
  //socket.emit('my other event', { my: 'data' });
});
