【问题描述】：

这是客户端js

  let user_id = $('meta[name="user-id"]').attr('content');
  let channel = Echo.join('user-' + user_id);
    channel.here((user) => {
      console.log('Here');
      console.log(user);
    })
    .joining((user) => {
        console.log('joining');
        console.log(user);
    })
    .leaving((user) => {
        console.log('leaving');
        console.log(user);
    });

在 laravel 回显服务器中显示此错误

 [11:48:15 AM] - wLO1jq5fW9p_8lOnAAAS left channel: presence-user-1 (transport close)

这是我的 MessageSent 事件

public function __construct($message,$id)
{
    $this->message = $message;
    $this->id = $id;
}

public function broadcastOn()
{
    return new PresenceChannel('user-'.$this->id);
}

这是我的控制台.php

Broadcast::channel('user-{id}', function ($user, $id) {
    return (int) $user->id === (int) $id;
});

但我的控制台很清晰，没有显示加入等的日志

【解决方案1】：

在您的广播回调中，您返回了一个由私人频道询问的布尔值。但是当你验证一个在线通道时，如果用户被允许，你必须返回一个关于这个用户的数据数组。
