我使用laravel 5.3

我像这样制作routes / channels.php:

<?php
Broadcast::channel('messages', function() {
    return true;
});

如果我输入数据购物车并点击提交,它将运行:

this.$http.post(window.BaseUrl + '/guest/add-notification', {cart_data: JSON.stringify(data)});

它将调用控制器上的函数

这样的功能:

public function addNotification(Request $request){
    $input = $request->only('cart_data');
    $data = json_decode($input['cart_data'], true);
    event(new CartNotificationEvent($data));
}

然后它将调用事件

这样的事件:

<?php
namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
class CartNotificationEvent
{
    use InteractsWithSockets, SerializesModels;
    public $data;
    public function __construct($data)
    {
        $this->data = $data;
    }
    public function broadcastWith()
    {
        return [
            'message' => $this->data,
        ];
    }
    public function broadcastAs()
    {
        return 'newMessage';
    }
    public function broadcastOn()
    {
        return new Channel('messages');
    }
}

在客户端,我喜欢这样:

Echo.channel('messages')
.listen('.newMessage', (message) => {
    console.log('test')
    console.log(message);
});

执行所有代码后,我检查控制台,console.log不显示

为什么不起作用?

如果我看到我制作的整个代码,那么过程似乎是正确的
