我正在尝试在数据更改时向用户发送广播通知。但是每次尝试发送通知时,都会出现此错误:
array_key_exists(): The first argument should be either a string or an integer
。
这是我的通知:
class MyNotification extends Notification
{
use Queueable;
public $games;
public $title;
public $summary;
public $url;
public function __construct($games)
{
$this->games = $games;
$this->title = "Your games";
$this->summary = "Games for {$games[0]->team}";
$this->url = "/some/url";
}
public function via($notifiable)
{
return ['mail','broadcast','database'];
}
/**
* Get the mail representation of the notification.
*
* @param mixed $notifiable
* @return \Illuminate\Notifications\Messages\MailMessage
*/
public function toMail($notifiable)
{
return (new MailMessage)
->subject($this->title)
->line($this->summary);
}
/**
* Get the voice representation of the notification.
*
* @param mixed $notifiable
* @return PushMessage
*/
public function toPush($notifiable)
{
// ...
}
public function toBroadcast($notifiable)
{
return new BroadcastMessage($this->toArray($notifiable));
}
/**
* Get the array representation of the notification.
*
* @param mixed $notifiable
* @return array
*/
public function toArray($notifiable)
{
return [
'icon' => 'fa fa-calendar',
'text' => $this->summary,
'title' => $this->title,
'url' => $this->url
];
}
}
当我从via
数组中删除“广播”时,一切正常。我不知道我在做什么错!有人可以帮忙吗?谢谢!

在通知的构造函数中,我有一个使用复合键的模型。当我删除以下行时:$this->games = $games;
,然后将$this->summary
编辑为某个字符串-它可以工作! $games
是模型Game
的集合。
但是我不知道为什么会这样?!
答案 0 :(得分:4)
如果我理解正确,原因仅是因为您的模型使用的是not supported by eloquent组合键。
所以这是我认为实际上是由于我对整个通知/广播模块的有限了解而发生的事情。
MyNotification
事件推送到队列中Notification
基类实际上实现了Illuminate\Queue\SerializesModels
特性,因此将自动尝试序列化通知类属性中的所有模型Game
对象的有说服力的集合时,该集合然后尝试在集合中的每个模型上调用getQueueableId
,然后失败,因为它尝试检索基于在您的组合键上对于解决方案,我会说尝试在模型上删除您的复合键,因为使用雄辩时似乎无法按预期工作。
// in Game model
protected $primaryKey = 'id';
根据此队列上的documentation,您也可以尝试在broadcastWith
类上添加MyNotification
方法,尽管我不确定是否会绕过SerializeModels
特性。
// in MyNotification
public function broadcastWith()
{
return ['id' => $this->id];
}
或者根据您自己的尝试和错误,您可以将其转换为数组,而不必使用集合初始化$this->games
。毕竟,最后,您的toBroadcast
方法是实际控制广播的方法。
$this->games = $games->toArray();
最后一个选择是覆盖getQueueableId()
模型的Game
方法。
// in Game Model
public function getQueueableId()
{
return $this->id;
// or if you still want to utilize your composite keys. UNTESTED
return $this->key_one.$this->key_two;
}
