Question

使用Pusher与Laravel 5.8实时发送消息会在NewMessage事件文件上生成此错误。我尝试进行调试的步骤：

试图删除“使用Dispatchable，InteractsWithSockets，SerializesModels”行。在班级内部；
尝试不使用文件顶部的类

这些都不起作用。在Laravel 5.8文档中，他们没有提到在事件类中使用此行，也许已经过时了？！

文件如下：

`

namespace StyxEminus\Events;
use StyxEminus\Message;
use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

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

public $message;

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

/**
 * Get the channels the event should broadcast on.
 *
 * @return \Illuminate\Broadcasting\Channel|array
 */
public function broadcastOn()
{
    return new PrivateChannel('messages.' . $this->message->to);
}

public function broadcastWith() {
    return ["message" => $this->message];
}
}`

Answer 1

您需要导入 Illuminate \ Foundation \ Bus \ Dispatchable

致命错误：在第14行的C：\ xampp \ htdocs \ chat-app \ app \ Events \ NewMessage.php中找不到特质'Illuminate \ Foundation \ Events \ Dispatchable'
