php - Laravel，获取 BroadcastOn() 的用户 ID

Question

我需要通过 BroadcastOn() 函数获取 channel 名称的用户 ID 吗？

我想做的是:

新事件:

event(new \App\Events\chat($message, $userid, $avatar, $username, $receiver, $msgid));

事件本身

public $message;
    public $user;
    public $avatar;
    public $username;
    public $receiver;

构建:

public function __construct($message, $user, $avatar,$username,$receiver,$msgid) {
        $this->message = $message;
        $this->user = $user;
        $this->avatar = $avatar;
        $this->username = $username;
        $this->receiver = $receiver;
        $this->msgid = $msgid;

    }

广播:

public function broadcastOn() {
        $user = \Auth::user()->id();
        return new Channel($user);
    }

如果我尝试 dd\Auth::user();它给了我 null，我想这是通过 auth 在事件中无法识别用户。有没有办法以某种方式将用户传递给 broadcastOn() 以便我可以将其定义为 channel 名称？

Answer 1

You can do like below as you have $user already in constructor

public function broadcastOn() {
{
 return ['channel_'.$this->user->id];
}

或者传递用户id

public function __construct($message, $user, $avatar,$username,$receiver,$msgid,$userid) {
        $this->message = $message;
        $this->user = $user;
        $this->avatar = $avatar;
        $this->username = $username;
        $this->receiver = $receiver;
        $this->msgid = $msgid;
       $this->userid= $userid;

    }

然后

public function broadcastOn() {
    {
     return ['channel_'.$this->userid];
    }
