ThinkPHP8使用workerman
应用场景说明：通过建立通信，不同用户进行消息推送或数据更新，因为本身需要作为服务端进行主动消息推送，因此使用Gateway方式，如果不需要的可以不采用这种形式，以下内容仅为参考，具体业务场景，自行修改！！！！
Linux或MacOS不需要进行自定义命令，直接使用php think worker:server php think worker:gateway 使用即可。
废话少说，直接开干！！！
你可能会碰到以下问题，仅供参考！
一、可能会出现问题
1.GatewayWorker Not Support On Windows.
此问题出现在启用命令php think worker:gateway之后，需要使用自定义命令进行修改，具体下面细说
2.Implicit conversion from float 999996.9005584717 to int loses precision
此问题，在自定义命令后，需进行如下修改：\vendor\workerman\workerman\Events\Selelct.php第215行，
usleep($this->_selectTimeout); // 修改为下面usleep((int)$this->_selectTimeout);二、不使用gateway
1.安装think-worker
composer require topthink/think-worker2.运行命令
php think worker 运行httpphp think worker:server 运行webscoket // 默认是2345端口 3.测试链接
// 新建一个html，直接复制以下代码，浏览器访问，打开控制台

<script>/*** 与GatewayWorker建立websocket连接，域名和端口改为你实际的域名端口，* 其中端口为Gateway端口，即start_gateway.php指定的端口。* start_gateway.php 中需要指定websocket协议，像这样* $gateway = new Gateway(websocket://0.0.0.0:7272);*/ws = new WebSocket("ws://127.0.0.1:2348");// 服务端主动推送消息时会触发这里的onmessagews.onopen = function () {// 触发系统自定义的test_event事件,发送json数据var data = {"type": "bind", "data": {"uid": "10001"}};ws.send(JSON.stringify(data));}ws.onmessage = function (e) {console.log(e.data);var data = {"type": "send", "data": {"uid": "10001", 'message': '呦吼'}};ws.send(JSON.stringify(data))}// ws.onmessage = onmessagews.onclose = function () {// 连接关闭，推送消息至服务端var data = {type: 'close', data: "{'uid':10001}"};ws.send(JSON.stringify(data));}</script>
</html>4、效果截图
监听的方法，默认在config/worker_server.php里面，也可以通过继承Server进行修改，具体方法参考手册。tp-workerman
三、使用Gateway
如果直接使用 php think worker:gateway 就会提示GatewayWorker Not Support On Windows.具体原因简单说明（php think worker:gateway就是在同一个php文件里启动了多个worker，因为不能成功运行所以tp的命令行提前做了判定，显示不支持在windows下运行），大家自行搜一下具体原因即可。
具体解决思路，自定义命令进行运行，根据以下步骤进行参考
1.创建命令
php think make:command common@WorkerMain2.复制以下代码到以上文件中
<?phpnamespace app\common\command;use GatewayWorker\BusinessWorker;
use GatewayWorker\Gateway;
use GatewayWorker\Register;
use think\console\Command;
use think\console\Input;
use think\console\input\Argument;

use think\console\Output;
use think\facade\Config;
use Workerman\Worker;/*** Worker 命令行*/
class WorkerMain extends Command

}3.运行命令
// 需依次运行以下命令php think WorkerMain gatewayphp think WorkerMain business_workerphp think WorkerMain register4.浏览器访问：端口需改成gateway端口，默认2348
