ubuntu16.04下workerman-gateway实现长连接弹幕系统聊天室案例

本文介绍了如何在Ubuntu16.04系统中利用workerman-gateway搭建长连接弹幕系统聊天室。内容包括gateway的介绍、环境搭建步骤、服务器消息处理方法,以及移动端聊天室的创建。通过这个案例,读者可以学习到如何处理客户端数据,实现数据的全局广播和特定客户端推送。

弹幕系统聊天室

gateway介绍

  • GatewayWorker基于Workerman开发的一个项目框架,用于快速开发TCP长连接应用,例如app推送服务端、即时IM服务端、游戏服务端、物联网、智能家居等等

  • GatewayWorker使用经典的Gateway和Worker进程模型。Gateway进程负责维持客户端连接,并转发客户端的数据给BusinessWorker进程处理,BusinessWorker进程负责处理实际的业务逻辑(默认调用Events.php处理业务),并将结果推送给对应的客户端。Gateway服务和BusinessWorker服务可以分开部署在不同的服务器上,实现分布式集群。

  • GatewayWorker提供非常方便的API,可以全局广播数据、可以向某个群体广播数据、也可以向某个特定客户端推送数据。配合Workerman的定时器,也可以定时推送数据。

环境搭建

下载安装gateway

root@iZwz94dunl1qornhtnn4gpZ:/www/web/default# wget -c http://www.workerman.net/download/GatewayWorker.zip

root@iZwz94dunl1qornhtnn4gpZ:/www/web/default# unzip GatewayWorker.zip

root@iZwz94dunl1qornhtnn4gpZ:/www/web/default# cd GatewayWorker

协议以及地址

  • 注意
ip:

1、如果写0.0.0.0代表监听本机所有网卡,也就是内网、外网、本机都可以访问到

2、如果是127.0.0.1,代表只能本机通过127.0.0.1访问,外网和内网都访问不到

3、如果是内网ip例如:192.168.10.11,代表只能通过192.168.10.11访问,也就是只能内网访问,本机127.0.0.1也访问不了(如果监听的ip不属于本机则会报错)

4、如果是外网ip例如110.110.110.110,代表只能通过外网ip 110.110.110.110访问,内网和本机127.0.0.1都访问不了(如果监听的ip不属于本机则会报错)

port:

端口不能大于65535,请确认端口没有被其它程序占用,否则启动会报错。如果端口小于1024,需要root权限运行GatewayWorker才能有权限监听,否则报错没有权限。
  • 修改start_gateway.php文件配置协议地址
root@iZwz94dunl1qornhtnn4gpZ:/www/web/default/GatewayWorker# vim Applications/YourApp/start_gateway.php

// 自动加载类
require_once __DIR__ . '/../../vendor/autoload.php';
$gateway = new Gateway("websocket://0.0.0.0:8081");
// gateway名称,status方便查看
$gateway->name = 'Lottery-2019';
// gateway进程数
$gateway->count = 4;
// 本机ip,分布式部署时使用内网ip

// 如果不是在根目录启动,则运行runAll方法
if(!defined('GLOBAL_START'))

服务器消息处理

当客户端有信息发送过来时,聊天室需要立即处理信息并广播给当前连接了服务器的所有人

  • 修改Events.php

//    }

运行服务器

后台运行聊天室
root@iZwz94dunl1qornhtnn4gpZ:/www/web/default/GatewayWorker# php start.php start -d

建立移动端聊天室

下面代码重的静态资源我这里就先不提供了,各位看官自行修改一下就行了。
里面有一些代码涵盖了以前的红包系统等,看官可无视。
