GatewayWorker手册https://www.kancloud.cn/walkor/gateway-worker/326105网站介绍很详细;
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。
Workerman可以看做是一个纯粹的socket类库,可以开发几乎所有的网络应用,不管是TCP的还是UDP的,长连接的还是短连接的。Workerman代码精简,功能强大,使用灵活,能够快速开发出各种网络应用。同时Workerman相比GatewayWorker也更底层,需要开发者有一定的多进程编程经验。
因为绝大多数开发者的目标是基于Workerman开发TCP长连接应用,而长连接应用服务端有很多共同之处,例如它们有相同的进程模型以及单发、群发、广播等接口需求。所以才有了GatewayWorker框架,GatewayWorker是基于Workerman开发的一个TCP长连接框架,实现了单发、群送、广播等长连接必用的接口。GatewayWorker框架实现了Gateway Worker进程模型,天然支持分布式多服务器部署,扩容缩容非常方便,能够应对海量并发连接。可以说GatewayWorker是基于Workerman实现的一个更完善的专门用于实现TCP长连接的项目框架。介绍这么多,你也大致了解GatewayWorker是什么了,我就在我的项目小程序上使用它做了一个聊天功能,这里都是我自己写的代码;
上面简单的聊天功能,是利用GatewayWorker长连接来做。目前运行很稳定,所以拿出来分享一下。因为关于Workerman的长连接网上资料还是很少的;下面就是我的代码展示;
Events.php文件里的消息接收和推送,这里是PHP逻辑的处理地方

心跳在文件start_gateway.php里面
// 心跳间隔 $gateway->pingInterval = 30; // 心跳数据 $gateway->pingData = '{"type":"ping"}';
前端访问的链接和GatewayWorker配置这需要大家看手册了,不难的,我当前Windows反向代理用的是Linux来实现的
我就暂时就写到这里,有不懂得,可以留言,我们一起交流,一起进步,,写的不好的地方可以留言,谢谢!
