您好，我目前正在使用 Laravel 學習 Vue.js 并嘗試開發團隊聊天。由于經濟原因，我使用了 redis 而不是 pusher，并使用了這個 laravel echo server作為 echo server。一旦您選擇了一個團隊，群聊就會將用戶連接到一個私人頻道。之后它加載消息并在前端顯示它們。當您發送消息時，控制器操作成功執行并且消息存儲在數據庫中。然而，用戶和其他團隊成員必須重新單擊團隊名稱并因此重新加載消息列表以獲取最新消息，盡管事件在回顯服務器上被觸發并且 Redis 接收到消息。這是當有人選擇團隊聊天并發送消息時我從回顯服務器得到的：[10:20:41 PM] - gK5b68mvO1goLE4nAAAI authenticated for: private-messages.11[10:20:41 PM] - gK5b68mvO1goLE4nAAAI joined channel: private-messages.11Channel: clash_finder_database_private-messages.11Event: App\Events\NewMessage這是我從監控 redis-server得到的：1589921588.805758 [0 127.0.0.1:37594] "PUBLISH" "clash_finder_database_private-messages.11" " {\"event\":\"App\\\\Events\\\\NewMessage\",\"data\":{\"message\": {\"id\":9,\"message\":\"test\",\"team_id\":11,\"user_id\":3,\"created_at\":\"2020-05-19 20:53:08\",\"updated_at\":\"2020-05-19 20:53:08\"},\"socket\":null},\"socket\":null}"我的NewMessage事件如下所示：namespace App\Events;use App\Message;use Illuminate\Broadcasting\Channel;use Illuminate\Broadcasting\InteractsWithSockets;use Illuminate\Broadcasting\PresenceChannel;use Illuminate\Broadcasting\PrivateChannel;use Illuminate\Contracts\Broadcasting\ShouldBroadcast;use Illuminate\Foundation\Events\Dispatchable;use Illuminate\Queue\SerializesModels;class NewMessage implements ShouldBroadcast{use Dispatchable, InteractsWithSockets, SerializesModels;public $message;/** * Create a new event instance. * * @param Message $message */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->team_id);}}
