thinkphp5+GatewayWorker+Workerman

项目地址  ttps://www.workerman.net/workerman-chat

thinkphp5+GatewayWorker+Workerman聊天室，可以多人聊天，指定某个人进行聊天，还可以切换聊天房间
Windows版安装
a) 安装thinkphp5：

composer create-project topthink/think tp5  --prefer-dist

b) 进入tp5的目录，安装Windows版本的workerman：

composer require workerman/workerman-for-win

c)安装Windows版本的gateway：

composer require workerman/gateway-worker-for-win

开始关键部分,服务端实现

然后在项目根目录 新增入口文件 start_register.php 、start_gateway.php 、start_businessworker.php三个入口文件

文件：start_register.php

<?php 
define('APP_PATH', __DIR__ . '/application/');
define('BIND_MODULE','index/Sregister');
// 加载框架引导文件
require __DIR__ . '/thinkphp/start.php';

文件：start_gateway.php

<?php
define('APP_PATH', __DIR__ . '/application/');
define('BIND_MODULE','index/Sgateway');
// 加载框架引导文件
require __DIR__ . '/thinkphp/start.php';

文件：start_businessworker.php

<?php
define('APP_PATH', __DIR__ . '/application/');
define('BIND_MODULE','index/Sbusinessworker');
// 加载框架引导文件
require __DIR__ . '/thinkphp/start.php';

d): 由于PHP-CLI在windows系统无法实现多进程以及守护进程,所以只能把三个文件放到bat文件，然后双击启动

bat文件：start_for_win.bat

php start_register.php start_gateway.php start_businessworker.phppause

代码目录截图

 启动程序

在项目的根目录下双击启动 start_for_win.bat

运行结果截图

linux版安装

a) 安装thinkphp5：

composer create-project topthink/think tp5  --prefer-dist

b) 进入tp5的目录，安装linux版本的workerman：

composer require topthink/think-worker

c) 安装linux版本的gateway：

composer require workerman/gateway-worker-for-win

 关键部分，服务端实现

控制器 appindexcontrollerGate

<?php 
/**
 * linux workerman例子测试
 * 需要在Linux系统控制台进行启动，启动文件位于根目录的start.php文件中
 * Windows无法进行同时启动多个协议
 * 由于PHP-CLI在windows系统无法实现多进程以及守护进程，所以windows版本Workerman建议仅作开发调试使用。
 */
namespace appindexcontroller;
use WorkermanWorker;
use GatewayWorkerGateway;
use GatewayWorkerRegister;
use GatewayWorkerBusinessWorker;
class Gate
{
    /**
     * 构造函数
     * @access public
     */
    public function __construct(){
        
        //初始化各个GatewayWorker
        //初始化register register 服务必须是text协议
        $register = new Register('text://0.0.0.0:1236');
    
        //初始化 bussinessWorker 进程
        $worker = new BusinessWorker();
        // worker名称
        $worker->name = 'ChatBusinessWorker';
        // bussinessWorker进程数量
        $worker->count = 4;
        // 服务注册地址
        $worker->registerAddress = '127.0.0.1:1236';
        //设置处理业务的类,此处制定Events的命名空间
        $worker->eventHandler = 'appindexcontrollerEvents';
        // 初始化 gateway 进程
        $gateway = new Gateway("websocket://0.0.0.0:7272");
        // 设置名称，方便status时查看
        $gateway->name = 'ChatGateway';
        $gateway->count = 4;
        // 分布式部署时请设置成内网ip（非127.0.0.1）
        $gateway->lanIp = '127.0.0.1';
        // 内部通讯起始端口，假如$gateway->count=4，起始端口为4000
        // 则一般会使用4000 4001 4002 4003 4个端口作为内部通讯端口
        $gateway->startPort = 2300;
        // 心跳间隔
        $gateway->pingInterval = 10;
        // 心跳数据
        $gateway->pingData = '{"type":"ping"}';
        // 服务注册地址
        $gateway->registerAddress = '127.0.0.1:1236';
    
        //运行所有Worker;
        Worker::runAll();
    }
}

入口文件
文件： start.php

<?php
/**
 * workerman + GatewayWorker
 * 此文件只能在Linux运行
 * run with command
 * php start.php start
 */
ini_set('display_errors', 'on');
if(strpos(strtolower(PHP_OS), 'win') === 0)
{
    exit("start.php not support windows.
");
}
//检查扩展
if(!extension_loaded('pcntl'))
{
    exit("Please install pcntl extension. See http://doc3.workerman.net/appendices/install-extension.html
");
}
if(!extension_loaded('posix'))
{
    exit("Please install posix extension. See http://doc3.workerman.net/appendices/install-extension.html
");
}
define('APP_PATH', __DIR__ . '/application/');
define('BIND_MODULE','chat/Gate');
// 加载框架引导文件
require __DIR__ . '/thinkphp/start.php';

启动程序

php start.php start

客户端跟Windows一样就可以了
