Reverb 是 Laravel 中用於即時事件廣播的 Pusher 的實用替代方案。本指南重點介紹在 Laravel 11 中為託管在 Cloudflare 後面且具有靈活 SSL 的即時製作系統配置 Reverb。
在深入設定之前,請確保您具備以下條件:
首先,您需要在 Laravel 專案中安裝 Reverb。執行以下 Composer 指令:
composer require laravel/reverb
安裝完成後,發布設定檔:
php artisan vendor:publish --provider="Laravel\Reverb\ReverbServiceProvider"
這將建立一個 config/reverb.php 文件,您可以在其中調整混響的設定。
以下是混響的配置範例:
<?php return [ 'default' => env('REVERB_SERVER', 'reverb'), 'servers' => [ 'reverb' => [ 'host' => env('REVERB_HOST', '0.0.0.0'), 'port' => env('REVERB_PORT', 6001), 'hostname' => env('REVERB_HOST'), 'options' => [ 'tls' => [], ], 'max_request_size' => env('REVERB_MAX_REQUEST_SIZE', 10_000), 'scaling' => [ 'enabled' => env('REVERB_SCALING_ENABLED', false), 'channel' => env('REVERB_SCALING_CHANNEL', 'reverb'), 'server' => [ 'url' => env('REDIS_URL'), 'host' => env('REDIS_HOST', '127.0.0.1'), 'port' => env('REDIS_PORT', '6379'), 'username' => env('REDIS_USERNAME'), 'password' => env('REDIS_PASSWORD'), 'database' => env('REDIS_DB', '0'), ], ], 'pulse_ingest_interval' => env('REVERB_PULSE_INGEST_INTERVAL', 15), 'telescope_ingest_interval' => env('REVERB_TELESCOPE_INGEST_INTERVAL', 15), ], ], 'apps' => [ 'provider' => 'config', 'apps' => [ [ 'key' => env('REVERB_APP_KEY'), 'secret' => env('REVERB_APP_SECRET'), 'app_id' => env('REVERB_APP_ID'), 'options' => [ 'host' => env('REVERB_HOST'), 'port' => env('REVERB_PORT', 443), 'scheme' => env('REVERB_SCHEME', 'https'), 'useTLS' => env('REVERB_SCHEME', 'https') === 'https', ], 'allowed_origins' => ['*'], 'ping_interval' => env('REVERB_APP_PING_INTERVAL', 60), 'activity_timeout' => env('REVERB_APP_ACTIVITY_TIMEOUT', 30), 'max_message_size' => env('REVERB_APP_MAX_MESSAGE_SIZE', 10_000), ], ], ], ];
確保在您的 .env 檔案中正確配置以下環境變數:
BROADCAST_CONNECTION=reverb QUEUE_CONNECTION=database REVERB_HOST=127.0.0.1 REVERB_PORT=6001 REVERB_APP_ID=<app-key> REVERB_APP_KEY=<app-key> REVERB_APP_SECRET=<app-secret> REVERB_SCHEME=http VITE_REVERB_APP_KEY="${REVERB_APP_KEY}" VITE_REVERB_HOST="example.com" VITE_REVERB_PORT=443 VITE_REVERB_SCHEME=https
使用下列 Artisan 指令產生新的事件類別:
php artisan make:event MessageSent
以下是 MessageSent 事件的範例實作:
<?php namespace App\Events; use Illuminate\Broadcasting\InteractsWithSockets; use Illuminate\Contracts\Broadcasting\ShouldBroadcast; use Illuminate\Foundation\Events\Dispatchable; use Illuminate\Queue\SerializesModels; use Illuminate\Broadcasting\Channel; class MessageSent implements ShouldBroadcast { use Dispatchable, InteractsWithSockets, SerializesModels; public $message; public function __construct($message) { $this->message = $message; } public function broadcastOn(): Channel { return new Channel('chat-channel'); } public function broadcastAs(): string { return 'message-sent'; } }
建立一個簡單的 Blade 模板來測試混響功能 (welcome.blade.php):
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta name="csrf-token" content="{{ csrf_token() }}"> <title>Laravel Reverb WebSocket Test</title> <script src="https://cdnjs.cloudflare.com/ajax/libs/pusher/8.3.0/pusher.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/laravel-echo/1.17.1/echo.iife.min.js"></script> </head> <body> <h1>Laravel Reverb WebSocket Test</h1> <p>Open the console to see WebSocket messages.</p> <button> <h2> Defining Routes </h2> <p>Below is the code to define the required routes:<br> </p> <pre class="brush:php;toolbar:false"><?php use Illuminate\Support\Facades\Route; use App\Events\MessageSent; Route::post('/send-message', function (\Illuminate\Http\Request $request) { event(new MessageSent($request->input('message'))); return response()->json(['success' => true]); }); Route::get('/', function () { return view('welcome'); });
執行以下命令以啟用必要的 Apache 模組:
sudo a2enmod proxy sudo a2enmod proxy_wstunnel sudo a2enmod rewrite
以下是 Apache VirtualHost 設定的範例設定:
<VirtualHost *:80> ServerAdmin admin@example.com ServerName example.com DocumentRoot /var/www/example.com/public ProxyPreserveHost On ProxyRequests Off ProxyPass /app ws://127.0.0.1:6001/app ProxyPassReverse /app ws://127.0.0.1:6001/app SetEnvIf X-Forwarded-Proto https HTTPS=on ErrorLog /var/www/logs/example.com_error.log CustomLog /var/www/logs/example.com_access.log combined </VirtualHost> <Directory /var/www/example.com> Options -Indexes +FollowSymLinks -MultiViews AllowOverride All Require all granted </Directory>
要啟動服務,您需要啟動事件工作執行緒和 Rebel 伺服器。
執行以下命令來啟動事件工作執行緒:
php artisan queue:work
使用下列指令在指定連接埠和主機上啟動 Rebel 伺服器:
php artisan reverb:start --port=6001 --host=0.0.0.0
如果您不使用 Laravel Echo 和 Pusher 的 CDN,則需要安裝所需的 npm 庫(pusher-js 和 laravel-echo)以將即時事件廣播整合到您的應用程式中。此設定需要前端建置流程來管理和捆綁專案中的庫。
對於使用完整 SSL 託管在 Cloudflare 後面的應用程序,必須使用正確定義的 SSL 憑證來配置單獨的 VirtualHost。這可確保安全的 WebSocket 通訊並避免 SSL/TLS 不匹配的問題,從而阻止 WebSocket 連線正常運作。
