Php Laravel Pusher数组_merge:参数2应为数组，给定null

我正在按照pusher的教程在网站上显示通知。一切都符合教程的要求，但是当我试图访问

localhost:8000/test

上的通知时，出现了这个特殊的错误，我不知道如何修复它

预期结果：通知发送消息

输出：数组_merge（）错误

这是我的

事件/ItemAdd

：

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

    public $user;
    public $message;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct($user)
    {
        $this->user = $user;
        $this->message = '{ $user } added an item';
    }

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

这是我的

    dd(event(new App\Events\ItemAdd('Someone')));
    return "Event has been sent!";
});

任何帮助都将不胜感激。

不管我说什么，我只是降级到pusher 4.1，在composer.json上查找

pusher

，并将版本更改为

4.1

，以防地球上除我以外的任何人遇到相同的错误。

这个错误在pusher http php库v5.0.1和Laravel v8.29.0中得到解决

您可以在以下问题中找到此问题的解决方案：

您可能需要使用

composer require pusher/pusher-php服务器^4.1

-此库的v5.0.0支持尚未添加到Laravel中

我看不出$params在错误中初始化的位置message@ibrahim-dogan i添加了一段函数，其中$params是declared，您可以尝试

$all_params=array_merge（$post_params，$params？？？[]）

让我知道它是否有效，你希望$params作为一个数组，但你调用触发器的地方可能会将其传递为null（顺便说一句，如果你的PHP版本小于7，它将不起作用）。我确实尝试过，它会抛出

apErrorException

，这并没有什么好的，我不认为我应该弄乱这些供应商的东西。虽然这个链接可能回答这个问题，最好在这里包括答案的基本部分，并提供链接供参考。如果链接页面发生更改，则仅链接的答案可能无效-
