篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了基于swoole+Redis的消息实时推送通知相关的知识，希望对你有一定的参考价值。

swoole+Redis将实时数据的推送

一实现功能

设计师订单如果设计师未抢单,超时(5分钟)设计订单时时给设计师派送,
设计师公众号中收到派单信息
设计发布者收到派单成功信息

环境

centos6.10
redis-4.0.2
swoole-src-4.4.12
php-7.1.5
MYsyql5.7

在centos6默认是gcc-4.7,安装swoole的时候需要升级到gcc-4.8

二实现流程

1.开启swoole server端监听
2.开启swoole client连接执行定时执行
3.使用swoole task 异步执行推送逻辑

开始监听

服务端窗口

# php71 pushServer.php

client连接执行开始任务

客户端窗口

# php71 pushClient.php start

默认start开启5个client tcp链接,每个链接开启一个1s定时器

开启后服务端窗口的变化

[root@111111 swoole_server]# php71 pushServer.php 
Client-1: 连接成功
reactor-7 Client-1 接受数据: data=start 
Client-1: 连接结束
Client-2: 连接成功
reactor-0 Client-2 接受数据: data=start 
Client-3: 连接成功
Client-2: 连接结束
reactor-7 Client-3 接受数据: data=start 
Client-3: 连接结束
Client-4: 连接成功
reactor-0 Client-4 接受数据: data=start 
Client-4: 连接结束
Client-5: 连接成功
reactor-7 Client-5 接受数据: data=start 
Client-5: 连接结束
2019-12-14 01:29:15reactor-7 client-1 timer-2: 定时器第1 次执行

redis添加数据

向order_designer_list队列中添加数据

127.0.0.1:6379> LPUSH order_designer_list 1912136916313##150481##1576140373##oLvqQwo25p5myELvO5VXj0k-7ngk##李伟测试##13926
(integer) 1
127.0.0.1:6379> LRANGE order_designer_list 0 10
1) "1912136916313##150481##1576140373##oLvqQwo25p5myELvO5VXj0k-7ngk##李伟测试##13926"

值为:
订单号##orderId##分配到期时间(uninx时间戳)##微信openid##设计师用户名##设计师userid

服务端窗口的变化

2019-12-14 01:29:15reactor-7 client-1 timer-2 taskid=0 :投递异步任务 data=1912136916313_150481_1576140373_oLvqQwo25p5myELvO5VXj0k-7ngk_李伟测试_13926
2019-12-14 01:29:15执行任务 id=0  data= 1912136916313_150481_1576140373_oLvqQwo25p5myELvO5VXj0k-7ngk_李伟测试_13926 
任务完成 id=0 结果=1912136916313_150481_1576140373_oLvqQwo25p5myELvO5VXj0k-7ngk_李伟测试_13926已经派单过

task任务执行逻辑

数据分析
数据通过微信消息模板接口,将信息内容发送到客户微信公众号上
将监控日志和错误日志写入mysql数据库
