ThinkPHP5集成GatewayWorker

  1. 通过composer安装GatewayWorker类库

在TP5根目录 窗口地址栏输入 cmd 通过 composer 安装 GatewayWorker

composer require workerman/workerman-for-win
composer require workerman/GatewayWorker-for-win
composer require workerman/gateway-worker-for-win (如果第二个下载不了,用这个)

如果还没有安装composer
可以通过 https://getcomposer.org/download/
下载,一直按 下一步 就行了

  1. 编写代码

在application目录下,创建一个应用模块,模块名称为gatewayapp,其目录结构如下:

controller/Index.php文件

<?php
namespace app\gatewayapp\controller;
 
use think\Controller;
 
class Index extends Controller {
 
    public function index() {
        return $this->fetch();
    }
}

view/index/index.html视图文件

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>WebSocket示例</title>
</head>
<body>
<script type="text/javascript">
 
    var webSocket = null;
 
    initSocket();
 
    function initSocket() {
        if (!"WebSocket" in window) {
            console.log("您的浏览器不支持 WebSocket!");
            return;
        }
        webSocket = new WebSocket("ws://"+document.domain+":8283");
        webSocket.onopen = handleSend;
        webSocket.onmessage = handleMessage;
        webSocket.onclose = handleClose;
        webSocket.onerror = handleError;
    }
 
    // 向服务器端发送数据
    function handleSend() {
        // Web Socket 已连接上,使用 send() 方法发送数据
        testing();
    }
 
    // 处理服务器端发送过来的数据
    function handleMessage(evt) {
        var received_msg = evt.data;
        console.log(received_msg);
    }
 
    // 处理连接关闭事件
    function handleClose() {
        console.log("连接已关闭...");
    }
 
    // 处理WebSocket错误
    function handleError() {
        console.log("WebSocketError!");
    }
    
    function testing() {
        //每隔3秒钟向服务器发送数据,此处仅用于测试
        var items = ['张三','李四','小二黑','阿杜','单工','大理寺','花荣','刘备','诸葛亮'];
        setInterval(function () {
            var item = items[Math.floor(Math.random()*items.length)];
            webSocket.send(item);
        },3000);
    }
    
</script>
</body>
</html>

        }
    }

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

const.php常量定义文件,根据需要,修改相关常量对应的值。

<?php
// 注册协议
define('GW_REGISTER_PROTOCOL','0.0.0.0:1236');
 
// 注册地址
define('GW_REGISTER_ADDRESS','127.0.0.1:1236');
 
// 网关地址
define('GW_GATEWAY_ADDRESS','0.0.0.0:8283');
 
// 网关起始端口
define('GW_GATEWAY_START_PORT','2900');
 
// 心跳检测间隔,单位:秒,0 表示不发送心跳检测
define('GW_GATEWAY_PING_INTERVAL',10);
 
// 本机ip,分布式部署时请设置成内网ip(非127.0.0.1)
define('GW_LOCAL_HOST_IP','127.0.0.1');
 
// 网关名称
define('GW_GATEWAY_NAME','Gateway001');
 
// worker进程名称
define('GW_WORKER_NAME','BusinessWorker001');
 
// Gateway进程数量,建议与CPU核数相同
define('GW_GATEWAY_COUNT',2);
 
// BusinessWorker进程数量,建议设置为CPU核数的1倍-3倍
define('GW_BUSINESS_WORKER_COUNT',6);
 
// Business业务处理类,可以带命名空间
define('GW_BUSINESS_EVENT_HANDLER','GwEvents');

}

最后
双击start_for_win.bat文件,启动websocket服务,启动成功后的界面如下:

浏览器输入
http://你配置的域名/gatewayapp/Index/Index
F12打开控制台即可看到js打印结果
