如何在 Laravel 5.5 中将一些变量传递给事件？我尝试了几种模式但没有工作。这是我的代码。有人有什么建议吗？基本上我需要通过套接字更新关注者的数量。使用 Redis 和 Socket.io 的服务器，也可以正常工作

 Route::post('follow', function() {
    $negozio = Input::get('id_azienda');
    $followers = new \App\Models\Followers;
    $followers->entry_by = \Session::get('uid');
    $followers->id_azienda = $negozio;
    $followers->save();
    $this->variabili['negozio'] = $negozio;
    $this->variabili['followers'] = $followers->count();
    event(new \App\Events\Follow(), $this->variabili);


});

这就是事件

<?php

namespace App\Events;

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

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

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public $variabili;

    public function __construct()
    {
        $this->data = array(
            'count'=> $variabili['followers'],
            'negozio'=> $variabili['negozio']
        );
    }

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return ['test-channel'];
    }
}

【解决方案1】：

您可以将它作为构造函数的参数传递到您的关注事件类中，如果您需要它作为公共字段，请执行以下操作：

    <?php

namespace App\Events;

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

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

    public $data;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct($variabili)
    {
        $this->data = array(
            'count'=> $variabili['followers'],
            'negozio'=> $variabili['negozio']
        );
    }

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return ['test-channel'];
    }
}

并以这种方式传递给他参数：

Route::post('follow', function() {
    $negozio = Input::get('id_azienda');
    $followers = new \App\Models\Followers;
    $followers->entry_by = \Session::get('uid');
    $followers->id_azienda = $negozio;
    $followers->save();
    $this->variabili['negozio'] = $negozio;
    $this->variabili['followers'] = $followers->count();
    event(new \App\Events\Follow($this->variabili));


});
