取消通知Laravel 5.3（Via）
问题描述：
So, let's say that I want to have my Notification Check logic within Via (as in, should this be sent based on a variable on the User). I notice that, if I do it this way in via:
return $notifiable->comment_email ? ['mail'] : false;
it will successfully send if comment_email is true on the User. However, if it is false, then I want the notification to be cancelled all together, which I assumed returning False would do - it does not, just throws an error. So how would I cancel it in the via? Is it possible?
所以，假设我想在Via中设置我的通知检查逻辑（如果是这样，应该基于此发送 在用户的变量上）。 我注意到，如果我这样做在via： p>
返回$ notifiable-＆gt; comment_email？ ['mail']：false;
code> pre>
如果用户的comment_email为true，它将成功发送。 但是，如果它是假的，那么我希望一起取消通知，我假设返回False会做 - 它不会，只是抛出一个错误。 那么如何在通道中取消它呢？ 有可能吗？ p>

答
instead return false you must return an empty array:
return $notifiable->comment_email ? ['mail'] : [];
