我有一個(gè)功能正常的通知系統(tǒng)，可以發(fā)布到我們公司 Slack 的頻道。但是，遇到的一切都只是文本。linkNames假設(shè)在您的內(nèi)容中查找/鏈接用戶名。我看到它被設(shè)置為“1”，但當(dāng)它出現(xiàn)在頻道中時(shí)沒有影響。 namespace App\Notifications;use Illuminate\Bus\Queueable;use Illuminate\Contracts\Queue\ShouldQueue;use Illuminate\Notifications\Notification;use Illuminate\Notifications\Messages\SlackMessage;class Dd extends Notification{use Queueable;/** * Create a new notification instance. * * @return void */public function __construct(){    //}/** * Get the notification's delivery channels. * * @param  mixed  $notifiable * @return array */public function via($notifiable){    return ['slack'];}/** * Get the array representation of the notification. * * @param  mixed  $notifiable * @return array */public function toArray($notifiable){    return [        //    ];}/** * Get the Slack representation of the notification. * * @param  mixed  $notifiable * @return SlackMessage */public function toSlack($slackComment){       $slackMessage = new SlackMessage();    $slackMessage->linkNames();    $slackMessage->from('Christopher');    $slackMessage->to($slackComment->channel);    $slackMessage->content("Harded coded for example @christopher <- this doesn't get linked to the user in slack but should");     $slackMessage->info();    //dd($slackMessage); // this shows that the linkedNames attribute has been set to "1"    return $slackMessage;             }}這是一個(gè)已知問題，版本不匹配，還是我遺漏了什么？
