tp5+workman(GatewayWorker) 安装及使用

一、安装thinkphp5

1、宝塔删除php禁用函数putenv、pcntl_signal_dispatch、pcntl_wai、pcntl_signal、pcntl_alarm、pcntl_fork，执行安装命令。

composer create-project topthink/think=5.0.* tp5  --prefer-dist

2、配置好站点之后，浏览器打开访问成功。

二、tp5安装GatewayWorker

1、进入tp5目录，安装GatewayWorker

composer require workerman/gateway-worker

2、安装workman

composer require workerman/workerman

3、安装gatewayclient

composer require workerman/gatewayclient

三、使用GatewayWorker

1、创建文件tp5/public/start.php

<?php
/**
 * run with command
 * php start.php start
 */

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();

2、创建文件tp5/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：".$client_id.PHP_EOL;
        // 向当前client_id发送数据 
        Gateway::sendToClient($client_id, "Hello $client_id\r\n");
        // 向所有人发送
        Gateway::sendToAll("$client_id login\r\n");
    }
    
   /**
    * 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, $message)
   {
        // 向所有人发送 
        Gateway::sendToAll("$client_id said $message\r\n");
   }
   
   /**
    * 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("$client_id logout\r\n");
   }
}

3、创建文件tp5/application/Socket/start_businessworker.php

<?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
if(!defined('GLOBAL_START'))
{
    Worker::runAll();
}

4、创建文件tp5/application/Socket/start_gateway.php

<?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");
// gateway名称，status方便查看
$gateway->name = 'YourAppGateway';
// gateway进程数
$gateway->count = 4;
// 本机ip，分布式部署时使用内网ip
$gateway->lanIp = '127.0.0.1';
// 内部通讯起始端口，假如$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 = 2900;
// 服务注册地址
$gateway->registerAddress = '127.0.0.1:1236';

// 心跳间隔
//$gateway->pingInterval = 10;
// 心跳数据
//$gateway->pingData = '{"type":"ping"}';

/* 
// 当客户端连接上来时，设置连接的onWebSocketConnect，即在websocket握手时的回调
$gateway->onConnect = function($connection)
{
    $connection->onWebSocketConnect = function($connection , $http_header)
    {
        // 可以在这里判断连接来源是否合法，不合法就关掉连接
        // $_SERVER['HTTP_ORIGIN']标识来自哪个站点的页面发起的websocket链接
        if($_SERVER['HTTP_ORIGIN'] != 'http://kedou.workerman.net')
        {
            $connection->close();
        }
        // onWebSocketConnect 里面$_GET $_SERVER是可用的
        // var_dump($_GET, $_SERVER);
    };
}; 
*/

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

5、创建文件tp5/application/Socket/start_register.php

<?php 
/**
 * This file is part of workerman.
 *

 * For full copyright and license information, please see the MIT-LICENSE.txt
 * Redistributions of files must retain the above copyright notice.
 *
 * @author walkor
 * @copyright walkor
 * @link http://www.workerman.net/
 * @license http://www.opensource.org/licenses/mit-license.php MIT License
 */
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();
}

6、启动websocket程序

1、防火墙打开8282、1236端口，执行下面命令

php start.php start

四、使用GatewayWorker发布广播

1、创建文件tp5/application/index/controller/Index.php，执行这个方法就可以向所有人发布广播了。

<?php
namespace app\index\controller;
use GatewayClient\Gateway;
class Index
{
    public function index()
    {
        Gateway::sendToAll(" index发的消息 \r\n");
    }
}
