netsvr-business-serial

可以快速开发websocket全双工通信业务的包，它必须在串行的php程序中工作，不能在协程中工作，它基于https://github.com/buexplain/netsvr 进行工作。

ps：如果你的项目是hyperf框架的，则可以使用这个包：https://github.com/buexplain/netsvr-business-coroutine

安装步骤

安装netsvr

点击链接：https://github.com/buexplain/netsvr/releases ，进去后下载网关程序，下载后启动网关服务，网关服务会启动：websocket服务器、worker服务器，请仔细阅读netsvr.toml文件。

在你的php项目里面安装本包以及protobuf包

composer require buexplain/netsvr-business-serial
composer require google/protobuf

在框架初始化阶段，初始化本包，步骤如下

Laravel框架

只要在你的laravel项目安装下面这个服务提供者，即可实现服务端主动下发数据到客户端，但是不能实现客户端主动向网关发送数据。

其它的fpm容器下运行的框架初始化方式大同小异，不再赘述。

若要实现双向通信，请参考文章：在laravel下实现全双工的websocket开发

完成以上步骤后

在你的业务代码中使用\NetsvrBusiness\NetBus::class 的静态方法与网关交互，示例：\NetsvrBusiness\NetBus::broadcast("将消息通过广播的方式给到全体在线人员");
