🗣 Wd提问: 程序PHP Laravel广播

🤖 Ai回答:
Laravel广播是一个允许实时将服务器端事件推送到客户端的功能，通常用于实时通知、聊天应用等场景。

基本设置

1、安装Laravel Echo和对应的广播驱动依赖:
bash
npm install laravel-echo pusher-js

2、配置`.env`文件:

BROADCAST_DRIVER=pusher
PUSHER_APP_ID=your-app-id
PUSHER_APP_KEY=your-app-key
PUSHER_APP_SECRET=your-app-secret
PUSHER_APP_CLUSTER=mt1

3、配置`config/broadcasting.php`:
php
'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,
],
],

4、配置`resources/js/bootstrap.js`:
javascript
import Echo from 'laravel-echo';

window.Pusher = require('pusher-js');

window.Echo = new Echo({
broadcaster: 'pusher',
key: process.env.MIX_PUSHER_APP_KEY,
cluster: process.env.MIX_PUSHER_APP_CLUSTER,
forceTLS: true,
});

创建广播事件

bash
php artisan make:event NewOrderNotification

修改事件类:
php
<?php

namespace App\Events;

use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;

class NewOrderNotification implements ShouldBroadcast
{
use Dispatchable, InteractsWithSockets, SerializesModels;

public $order;

public function __construct($order)
{
$this-order = $order;
}

public function broadcastOn()
{
return new PrivateChannel('orders.' 、$this-order-user_id);
}

public function broadcastAs()
{
return 'new.order';
}

public function broadcastWith()
{
return [
'order_id' = $this-order-id,
'total' = $this-order-total,
'created_at' = $this-order-created_at-toDateTimeString(),
];
}
}

触发广播事件

php
use App\Events\NewOrderNotification;

// 在控制器中
event(new NewOrderNotification($order));

前端监听事件

javascript
// 监听特定用户的新订单通知
Echo.private('orders.' + userId)
.listen('.new.order', (e) = {
console.log(e.order_id);
// 处理新订单通知
});

频道认证

在`routes/channels.php`中:
php
use Illuminate\Support\Facades\Broadcast;

Broadcast::channel('orders.{userId}', function ($user, $userId) {
return (int) $user-id === (int) $userId;
});

其他广播驱动

除了Pusher，Laravel还支持:
Redis
Ably
Log (仅用于开发)
Null (禁用广播)

根据项目需求选择合适的广播驱动，并安装相应的依赖包进行配置。
