Question

我正在触发事件并使用这样的数组传递对象：

$event = new App\Events\SendMessage;
$event->msg = [ 'sender_id'=>'191', 
                'recepient_id'=>'190',
                'text'=>'some text',
              ];
Event::fire($event);

是否可以将此调用缩短一点并在一行中触发事件？

Event::fire(new App\Events\SendMessage([
                        'sender_id'=>'191', 
                        'recepient_id'=>'190',
                        'text'=>'some text',
                    ]));

Answer 1

您只需确保设置事件构造函数以填充该字段。

请参阅：http://laravel.com/docs/5.1/events#defining-events

<?php

namespace App\Events;

use App\Events\Event;
use Illuminate\Queue\SerializesModels;

class SendMessage extends Event
{
    use SerializesModels;

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

Answer 2

是的。只需传递__construct()

中的数据即可

class SendMessage extends Event
{
    protected $data;
    public function __construct(array $data)
    {
        $this->data = $data;
    }
}

Answer 3

在App\Events\SendMessage中，您需要定义构造函数方法，例如：

namespace App\Events;

class SendMessage {

    protected $data = null;

    public function __construct(Array $data)
    {
        $this->data = $data;
    }
}

Answer 4

您可以在laravel中触发此类事件

只需将代码放入控制器

event(new App\Events\EventClassName());

如果您的事件具有参数，则

event(new App\Events\EventClassName(['first' => 'value','second' => 'value']));
