構建基於事件的消息推送系統
事件分為: 優惠券、預訂業務 系統業務場景 1 客服通過基於開源sphinx搭建的搜索系統
簡要代碼實現
1 搭建GearmanWork 異步通知銀行系統生成唯一訂單號
#PHP#!/usr/local/php/bin/php -q
addServer("127.0.0.1",4730);
$worker->addFunction("xdAction", "xdAction_fn");while (1){
$ret = $worker->work();
if ($worker->returnCode() != GEARMAN_SUCCESS)
{
break;
}}function xdAction_fn($a){
$devAuth = array(
'appID:100132695302118',
'APPKEY:22713038b5ddb849a6f9853e18b3dfd3'
);
$rw=unserialize($a->workload());
echo $json = kerHttpRest::connect( 'http://xxxxx')
->header($devAuth)
->post($rw);
$row = json_decode($json);
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$lname = 'xdQueue'; //下單隊列
$arra = array(
'accessid' => 'xxxxxxxxxxxxx'
);
$redis->lpush($lname, json_encode($arra));}#PHP
2 程序端調用GearmanWork
#PHP
addServer("127.0.0.1");
$newarray=serialize(array('platformid'=>'KLB00001','order_mobile'=>'130XXXXXXXX'));
$client->doBackground("xdAction",$newarray,md5(time()));#/PHP
3 nodejs非阻塞調用redis的信息 推送到client
...var redis = require("redis"),
client = redis.createClient(6379,'127.0.0.1');
client.on("error", function (err){
console.log("Error " + err);});
setInterval(function(){
client.rpop("xdQueue",function (err,value)
{
if(value!=null)
{
console.log(" " + ": " + value);
io.sockets.emit("neworder",value);
}
});};},1000);...
4 客戶端連接node服務 等待推送數據
var socket = io.connect('http://127.0.0.1:1337');
socket.emit('login', {'socketId':"xxxxx", mobile:"xxxxxx",accessid: "96e79218965eb72c92a549dd5a330112"});
socket.on('neworder', function (data){
var rw = eval('('+data+')');
$('.booking_order_count').show();
var v=$('.booking_order_count').html();
$('.booking_order_count').html(parseInt(v)+1);
console.log(rw.accessid);});
