记录一下fastadmin(thinkphp5.0)安装workman的过程
workman可以用来做即时通信 比如聊天

安装之前请确保php的putenv函数没有被禁用 如果被禁用了会报错
本流程用的是宝塔操作面板

首先唤起终端 确保终端当前目录是项目的根目录 如果不是手动 cd 项目完整路径 进入

安装GatewayWorker

GatewayWorker基于Workerman开发的一个项目框架

composer require workerman/gateway-worker

安装Workman

composer require workerman/workerman

安装GatewayClient

利用GatewayClient连接GatewayWorker,主动推送数据给前端页面

composer require workerman/gatewayclient

创建启动文件

在项目根目录创建start.php

<?php
/**
 * run with command
 * php start.php start
 */
define('DS', DIRECTORY_SEPARATOR);
define('ROOT_PATH', __DIR__ . DS);

ini_set('display_errors', 'on');
use Workerman\Worker;

if(strpos(strtolower(PHP_OS), 'win') === 0)
{
    exit("start.php not support windows, please use start_for_win.bat\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");
}

// 标记是全局启动
define('GLOBAL_START', 1);

require_once __DIR__ . '/vendor/autoload.php';
// 加载所有Applications/*/start.php,以便启动所有服务
foreach(glob(__DIR__.'/application/Socket/start*.php') as $start_file)
{
    require_once $start_file;
}
// 运行所有服务
Worker::runAll();

创建Events.php文件

先新建一个Socket目录 application/Socket
在Socket目录创建Events.php
application/Socket/Events.php

<?php

/**
 * 用于检测业务代码死循环或者长时间阻塞等问题
 * 如果发现业务卡死,可以将下面declare打开(去掉//注释),并执行php start.php reload
 * 然后观察一段时间workerman.log看是否有process_timeout异常
 */
//declare(ticks=1);

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
 */
class Events
{
    /**
     * 当客户端连接时触发
     * 如果业务不需此回调可以删除onConnect
     * 
     * @param int $client_id 连接id
     */
    public static function onConnect($client_id)
    {
        echo "【新的客户端链接】:client_id:".$client_id.PHP_EOL;
        // 向所有人发送 
        GateWay::sendToAll("用户《 $client_id 》已加入");
        // 向当前client_id发送数据 
        Gateway::sendToClient($client_id, "你好啊用户《 $client_id 》");
    }
    
   /**
    * 当客户端发来消息时触发
    * @param int $client_id 连接id
    * @param mixed $message 具体消息
    */
   public static function onMessage($client_id, $message)
   {
        // 向当前client_id发送数据
        Gateway::sendToClient($client_id, "已收到您的消息!");
   }
   
   /**
    * 当用户断开连接时触发
    * @param int $client_id 连接id
    */
   public static function onClose($client_id)
   {
       // 向所有人发送 
       GateWay::sendToAll("用户《 $client_id 》已下线");
   }
}

创建start_businessworker.php文件

在application/Socket目录创建start_businessworker.php
application/Socket/start_businessworker.php

use Workerman\Worker;
use Workerman\WebServer;
use GatewayWorker\Gateway;
use GatewayWorker\BusinessWorker;
use Workerman\Autoloader;

// 自动加载类
require_once __DIR__ . '/../../vendor/autoload.php';

// bussinessWorker 进程
$worker = new BusinessWorker();
// worker名称
$worker->name = 'YourAppBusinessWorker';
// bussinessWorker进程数量
$worker->count = 4;
// 服务注册地址
$worker->registerAddress = '127.0.0.1:1236';

// 如果不是在根目录启动,则运行runAll方法

创建start_gateway.php文件

在application/Socket目录创建start_gateway.php
application/Socket/start_gateway.php

use \Workerman\Worker;
use \Workerman\WebServer;
use \GatewayWorker\Gateway;
use \GatewayWorker\BusinessWorker;
use \Workerman\Autoloader;

// 自动加载类
require_once __DIR__ . '/../../vendor/autoload.php';

// gateway 进程,这里使用Text协议,可以用telnet测试
$gateway = new Gateway("websocket://0.0.0.0:8282");

}; 
*/

// 如果不是在根目录启动,则运行runAll方法

创建start_register文件

在application/Socket目录创建start_register.php
application/Socket/start_register

 */
use \Workerman\Worker;
use \GatewayWorker\Register;

// 自动加载类
require_once __DIR__ . '/../../vendor/autoload.php';

// register 必须是text协议
$register = new Register('text://0.0.0.0:1236');

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

启动WebSocket程序

放行端口8282、1236
在项目根目录执行下面启动命令
关闭命令窗口会停止服务

php start.php start

线上运行可以用守护进程启动,调试期间还是用普通命令启动方便
如果想守护进程启动可以用下面这个命令

php start.php start -d

在项目中对客户端发送消息

先引入
use GatewayClient\Gateway;

然后就可以调用
Gateway::sendToAll("向所有客户端发送消息");

演示如下

<?php
namespace app\index\controller;
use GatewayClient\Gateway;
class Index
{
    public function index()
    {
        // 向所有客户端发送消息
        Gateway::sendToAll("向所有客户端发送消息");
    }
    
    public function toMsg(){
        
        // 要发送的消息
        $msg = input('msg');
        
        // 客户端的ID
        $client_id = input('cid');
        
        // 向指定客户端发送消息
        Gateway::sendToClient($client_id, $msg);
    }
}
