Laravel Pusher錯誤「無回調」錯誤

Question

我正在嘗試使用Laravel 5.3和Pusher爲我的Web應用程序構建實時通知。我能夠將消息推送到Pusher調試控制檯。 我的服務器端腳本：

$options = array(
        'cluster' => 'ap2', 
        'encrypted' => true 
      ); 
      $pusher = new Pusher(
        'xxxxxxxxxx', // removed for safety 
        'xxxxxxxxxx', // removed for safety 
        'xxxxx', // removed for safety 
        $options 
      ); 

      $data['message'] = ($user->name)." like your status"; 
      $pusher->trigger('my-channel', 'PusherEvent', $data); 

而我的客戶端腳本：

<script src="https://js.pusher.com/4.0/pusher.min.js"></script> 

// Enable pusher logging - don't include this in production 
Pusher.logToConsole = true; 

var pusher = new Pusher('xxxxxxxxx', { 
    cluster: 'ap2', 
    encrypted: true 
}); 

var channel = pusher.subscribe('my-channel'); 
channel.bind('PusherEvent', function(data) { 
    alert(data.message); 
}); 

我想在我的webpage.Javascript警報已啓用我瀏覽器控制檯顯示如下：

Pusher : Event sent : {"event":"pusher:subscribe","data":{"channel":"my-channel"}} pusher.min.js:8:2594 
Pusher : Event recd : {"event":"pusher_internal:subscription_succeeded","data":{},"channel":"my-channel"} 
Pusher : No callbacks on my-channel for pusher:subscription_succeeded 

這可能是什麼原因？

對於名爲pusher_internal:subscription_succeeded的事件，您沒有任何綁定。這是正常的，沒有什麼可擔心的。當您訂閱某個頻道時，會觸發您未收聽的事件。

如果您遇到了一個名爲PusherEvent的事件並獲得了該回調消息，則應該關注。
