在Laravel中可以通过使用Laravel Echo和Laravel WebSockets来实现实时聊天应用。下面是实现步骤:
composer require beyondcode/laravel-websockets
php artisan vendor:publish --provider="BeyondCode\LaravelWebSockets\WebSocketsServiceProvider" --tag="config"
php artisan migrate
config/broadcasting.php
文件中配置:'connections' => [
'pusher' => [
'driver' => 'pusher',
'key' => env('PUSHER_APP_KEY'),
'secret' => env('PUSHER_APP_SECRET'),
'app_id' => env('PUSHER_APP_ID'),
'options' => [
'cluster' => env('PUSHER_APP_CLUSTER'),
'useTLS' => true,
],
],
],
.env
文件中配置 Pusher 相关信息:PUSHER_APP_ID=your-pusher-app-id
PUSHER_APP_KEY=your-pusher-app-key
PUSHER_APP_SECRET=your-pusher-app-secret
PUSHER_APP_CLUSTER=your-pusher-app-cluster
php artisan make:event MessageSent
在事件类的构造函数中传入消息内容:
public $message;
public function __construct($message)
{
$this->message = $message;
}
php artisan make:channel ChatChannel
在频道认证类中,授权用户访问频道:
public function join($user, $channel)
{
return true;
}
import Echo from "laravel-echo"
window.Echo = new Echo({
broadcaster: 'pusher',
key: 'your-pusher-app-key',
cluster: 'your-pusher-app-cluster',
encrypted: true,
});
window.Echo.channel('chat')
.listen('MessageSent', (e) => {
console.log(e.message);
});
use App\Events\MessageSent;
$message = "Hello, world!";
broadcast(new MessageSent($message))->toOthers();
这样就可以在 Laravel 中使用 WebSockets 实现实时聊天应用了。
