我laravel-echo用来收听我的 laravel WebSocket 频道。

我将此添加到我的app.js：

import Echo from 'laravel-echo'

/*..........*/

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

window.Echo = new Echo({
  broadcaster: 'pusher',
  key: 'appKey',
  wsHost: window.location.hostname,
  wsPort: 6001,
  forceTLS: false,
  disableStats: true
})

我有一个名为WebsocketMeasurements：

<?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;
Use App\Measurement;

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

    public $measurement;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct(Measurement $measurement)
    {
        $this->measurement = $measurement;
    }

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return new Channel ('measurement.created');
    }
}

我将此添加到我的dashboard.vue文件中：

mounted () {
    window.Echo.channel('measurement.created').listen('WebsocketMeasurements', (e) => {
      console.log(e)
    })
  },

当我尝试在 /laravel-websockets 触发测试事件时，没有任何反应。我填写以下数据： Channel: measurement.created Event: WebsocketMeasurements`` Data: {"data": null}`

我期望发生的是{"data": null}在控制台中接收，但那里没有任何记录。

通风口确实作为 api 消息显示在 laravel-websockets 的事件列表中，其中包含以下详细信息： Channel: measurement.created, Event: WebsocketMeasurements

我还尝试在我的仪表板 vue 中创建Channel一个PrivateChannel并更改window.Echo.channel为window.Echo.private，这导致链接 /broadcaster/auth 出现 403 错误。

在开始之前，我在终端中执行了以下命令： php artisan serve npm run hot php artisan queue:work php artisan websockets:serve php artisan queue:listen

我也尝试运行npm run watch而不是热运行，这没有帮助。

我通过更换来修复它

window.Echo.channel('measurement.created').listen('.WebsocketMeasurements', (e) => {
      console.log(e)
      this.websockets.push(e)
    })

和

Echo.channel('measurement.created').listen('.WebsocketMeasurements', (e) => {
      console.log(e)
      this.websockets.push(e)
    })
