为你的 Laravel 应用添加一个基于 Swoole 的 WebSocket 服务

做了一个基于 Swoole 的 WebSocket 扩展包，可以用来做实时状态推送，或者自定义消息处理实现 im，有需要的可以看看: [giorgio-socket]

使用方法

安装

安装扩展包

composer require wu/giorgio-socket

发布配置文件

php artisan vendor:publish --provider="GiorgioSocket\Providers\SocketServiceProvider"

运行 Socket 服务

php artisan socket:start

注意事项

• 可以通过实现 GiorgioSocket\Services\Handlers\Interfaces 下的接口类来自定义自己的业务逻辑。
• 如果要从服务端发送消息，这里有两种方式：
  • 第一种，借助 Laravel HTTP 客户端

    Route::get('/socket', function () {
        \Illuminate\Support\Facades\Http::asForm()->post('http://127.0.0.1:9501', [
            'to' => 2,
            'message' => 'server message',
        ]);
    });

  • 第二种：借助 Laravel Listener，需要将 .env 文件中的 QUEUE_CONNECTION 配置修改为 redis 或其他异步队列。配置更改后，运行以下命令：php-artisan queue:work --queue=socket-listener监听队列，然后按以下代码调用 event：

    Route::any('socket', function (Request $request){
        \GiorgioSocket\Events\SocketEvent::dispatch($request->get('to'), $request->get('message'));
    });

• 如果你正在使用 laravel/breeze 扩展包，并且使用了 Blade 模板，可以将以下代码粘贴到 dashboard.blade.php 中进行快速测试：

          <div class="max-w-7xl mx-auto sm:px-6 lg:px-8">
