WDPHP素材源码最近在自主开发在线客服系统，开发采用THINKPHP5+GatewayWorker+Workerman 希望对大家有所帮助

前置工作

开发是LINUX环境进行，使用composer安装相关类库。

推荐PHP5.6

WINDOWS用户请替换为workerman-for-win 和 GatewayWorker-for-win

1、安装ThinkPHP

2、在安装目录下

composer require workerman/workerman
composer require workerman/gateway-worker

程序目录截图

开始关键部分

1、添加入口文件
在项目根目录新增启动服务文件server.php，用于在cli模式下运行

#!/usr/bin/env php
<?php
ini_set('display_errors', 'on');
if(strpos(strtolower(PHP_OS), 'win') === 0)
{
    exit("start.php not support windows.\n");
}
// 检查扩展
if(!extension_loaded('pcntl'))
{
    exit("Please install pcntl extension. See http://doc3.workerman.net/appendices/install-extension.html\n");
}
if(!extension_loaded('posix'))
{
    exit("Please install posix extension. See http://doc3.workerman.net/appendices/install-extension.html\n");
}


define('APP_PATH', __DIR__ . '/apps/');

define('BIND_MODULE','push/Run');

// 加载框架引导文件
require __DIR__ . '/thinkphp/start.php';

控制器：app\push\controller\Run

<?php
namespace app\push\controller;

use Workerman\Worker;
use GatewayWorker\Register;
use GatewayWorker\BusinessWorker;
use GatewayWorker\Gateway;


class Run{
  /**
     * 构造函数
     * @access public
     */
    public function __construct(){
		
		//由于是手动添加，因此需要注册命名空间，方便自动加载，具体代码路径以实际情况为准
        \think\Loader::addNamespace([
            'Workerman' => VENDOR_PATH . 'Workerman/workerman',
            'GatewayWorker' =>VENDOR_PATH . 'Workerman/gateway-worker/src',
        ]);
		
        //初始化各个GatewayWorker
		//初始化register
		new Register('text://0.0.0.0:1238');
		 
		 //初始化 bussinessWorker 进程
		$worker = new BusinessWorker();
		$worker->name = 'WebIMBusinessWorker';
		$worker->count = 4;
		$worker->registerAddress = '127.0.0.1:1238';
		
		//设置处理业务的类,此处制定Events的命名空间
		$worker->eventHandler = '\app\push\controller\Events';
		
		// 初始化 gateway 进程
		$gateway = new Gateway("websocket://0.0.0.0:8282");
		$gateway->name = 'WebIMGateway';
		$gateway->count = 4;
		$gateway->lanIp = '127.0.0.1';
		$gateway->startPort = 2900;
		$gateway->registerAddress = '127.0.0.1:1238';
		 
		 //运行所有Worker;
		Worker::runAll();
    }
}

控制器：app\push\controller\Events
Events控制器负责业务处理

<?php
namespace app\push\controller;

use GatewayWorker\Lib\Gateway;
/**
 * 主逻辑
 * 主要是处理 onConnect onMessage onClose 三个方法
 * onConnect 和 onClose 如果不需要可以不用实现并删除
 */

    * @param mixed $data 具体消息
    */
