Laravel Pusher错误"No Callback“错误

Question

我正在尝试使用Laravel 5.3和Pusher for my Web-Applicatin构建实时通知。我可以将消息推送到Pusher调试控制台。我的服务器端脚本：

$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);

和我的客户端脚本：

<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browser.My浏览器控制台中启用我的webpage.Javascript时获得警报，控制台显示如下所示：

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

这可能是什么原因?？

Answer 1

您没有任何名为pusher_internal:subscription_succeeded的事件的绑定。这很正常，没什么好担心的。当你订阅一个频道时，会触发一个你没有监听的事件。

如果您获得了一个名为PusherEvent的事件并获得了该回调消息，那么您应该关注它。
