我无法让这段代码工作（laravel5.4/notifications#broadcast-notifications）：
Echo.private('App.User.' + userId)
.notification((notification) => {
console.log(notification.type);
});
这是我的代码：
app.js：
require('./bootstrap')
import Echo from 'laravel-echo'
window.Echo = new Echo({
broadcaster: 'socket.io',
host: 'http://127.0.0.1:6001'
})
window.Echo.private('App.User.' + window.Laravel.user.id)
.notification((notification) => {
console.log(notification);
// toastr.info(' has created new ticket !! ', 'info');
});
创建TekitNotify：
<?php
namespace App\Notifications\Ticket;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
use Illuminate\Notifications\Messages\BroadcastMessage;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Queue\SerializesModels;
use App\Models\Ticket\Ticket;
class CreateTicketNotify extends Notification implements ShouldQueue, ShouldBroadcast
{
use Queueable, SerializesModels;
public $ticket;
/**
* Create a new notification instance.
*
* @return void
*/
public function __construct($ticket)
{
$this->ticket = $ticket;
}
/**
* Get the notification's delivery channels.
*
* @param mixed $notifiable
* @return array
*/
public function via($notifiable)
{
return ['broadcast'];
}
/**
* Get the mail representation of the notification.
*
* @param mixed $notifiable
* @return \Illuminate\Notifications\Messages\MailMessage
*/
public function toMail($notifiable)
{
$url = url('/ticket/'.$this->ticket->id);
return (new MailMessage)
->subject('New Ticket Created')
->greeting('Hello, '.$this->ticket->user->lastname.' !')
->line('A new ticket has been created')
->action('View Ticket', $url)
->line('Thank you for using our application!');
}
/**
* Get the array representation of the notification.
*
* @param mixed $notifiable
* @return array
*/
public function toArray($notifiable)
{
return [
'ticket_id' => $this->ticket->id,
];
}
// public function toDatabase($notifiable)
// {
// return [
// ];
// }
public function toBroadcast($notifiable)
{
return new BroadcastMessage([
'ticket' => $this->ticket
]);
}
}
路线 ：
Route::get('/test', function() {
$user = \App\User::find(2);
$user->notify(new \App\Notifications\Ticket\CreateTicketNotify('Hello There'));
return "Event has been sent!";
});
渠道路线：
Broadcast::channel('App.User.{id}', function ($user, $id) {
return (int) $user->id === (int) $id;
});
Broadcast::channel('ticket.{id}', function ($user, $id) {
// $ticket = App\Models\Ticket\Ticket::find($ticketID);
// return $ticket->category->users->has(Auth::id());
// if(Auth::id()==1)
// if($id == 0)
// return false;
// else
return true;
$ticket = App\Models\Ticket\Ticket::find($id);
if (in_array(Auth::id(), $ticket->category->users->pluck('id')->toArray()) )
return true;
else
return false;
// return (int) $user->id !== (int) App\Models\Ticket\Ticket::find($ticketID)->user->id;
// else
// return false;
});
用户模型：
<?php
namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Spatie\Permission\Traits\HasRoles;
use Spatie\MediaLibrary\HasMedia\HasMediaTrait;
use Spatie\MediaLibrary\HasMedia\Interfaces\HasMedia;
use Auth;
class User extends Authenticatable implements HasMedia
{
use Notifiable, HasRoles, HasMediaTrait;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'lastname', 'firstname', 'email', 'password', 'active',
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
public function tickets()
{
return $this->hasMany('App\Models\Ticket\Ticket');
}
public function receivesBroadcastNotificationsOn()
{
return 'users.'.$this->id;
}
}
创建票务事件
<?php
namespace App\Events;
use App\Events\Event;
use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Contracts\Queue\ShouldQueue;
use App\Models\Ticket\Ticket;
class CreateTicketEvent implements ShouldQueue, ShouldBroadcast
{
use Dispatchable, InteractsWithSockets, SerializesModels;
public $ticket;
/**
* Create a new event instance.
*
* @return void
*/
public function __construct(Ticket $ticket)
{
$this->ticket = $ticket;
// $this->ticket = array(
// 'power'=> '10'
// );
}
/**
* Get the channels the event should broadcast on.
*
* @return Channel|array
*/
public function broadcastOn()
{
return new PrivateChannel('ticket.' . $this->ticket->id);
// return ['ticket'];
}
// public function broadcastWith()
// {
// return array('subject' => $this->ticket->subject);
// }
}
我的终端：
控制台输出：
[03:31:28] - 8bnJMpO-fFVs9LSyAAAE joined channel: ticket
[03:31:28] - 8bnJMpO-fFVs9LSyAAAE authenticated for: private-App.User.2
[03:31:28] - 8bnJMpO-fFVs9LSyAAAE joined channel: private-App.User.2
Channel: private-users.2
Event: Illuminate\Notifications\Events\BroadcastNotificationCreated
CHANNEL private-users.2
如您所见，用户 2 已加入频道并且已触发通知，但使用以下内容未显示任何内容：
window.Echo.private('App.User.' + window.Laravel.user.id)
.notification((notification) => {
console.log(notification);
// toastr.info(' has created new ticket !! ', 'info');
});
