Redis未在Laravel 5.1中接收广播事件 [英] Redis not picking up Broadcast events in Laravel 5.1

问题描述

我有以下事件:

<?php

namespace SixtyFiveContrib\Events;

use Auth;

use SixtyFiveContrib\Events\Event;
use SixtyFiveContrib\Models\Notification;

use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

/**
 * NotificationEvent 
 *
 */
class NotificationEvent extends Event implements ShouldBroadcast
{
    use SerializesModels;

    public $notification;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct(Notification $notification)
    {
        $this->notification = $notification;
    }

    /**
     * Get the channels the event should be broadcast on.
     *
     * @return array
     */
    public function broadcastOn()
    {
        return ['feed', 'updates'];
    }

    public function broadcastWith()
    {
        return ['notification' => $this->notification];
    }
}

我在broadcast.php中使用Redis驱动程序

I'm using the Redis driver in broadcasting.php

 'redis' => [
            'driver' => 'redis',
            'connection' => 'default',
        ],

然后我有来自官方文档的节点应用程序，该应用程序运行良好并且可以连接到客户端:

Then I have the node app from the official docs, which runs fine and connects to the client:

var app = require('http').createServer(handler);
var io = require('socket.io')(app);

var Redis = require('ioredis');
var redis = new Redis();

app.listen(3000, function() {
    console.log('Server is running!');
});

function handler(req, res) {
    res.writeHead(200);
    res.end('Ayup.');
}

io.on('connection', function(socket) {
    //
});

redis.psubscribe('*', function(err, count) {
    console.log(err);
});

redis.on('pmessage', function(subscribed, channel, message) {
    message = JSON.parse(message);

    console.log(subscribed);
    console.log(channel);
    console.log(message);

    io.emit(channel + ':' + message.event, message.data);
});

节点应用程序没有从Redis接收任何信息吗?如果我手动进入redis-cli并运行```PUBLISH feed'{event:"SixtyFiveContrib \ Events \ NotificationEvent"}'，则节点应用程序确实会收到该消息.

The node app isn't receiving anything from Redis? If I manually go into redis-cli and run ``` PUBLISH feed '{event: "SixtyFiveContrib\Events\NotificationEvent"}' then the node app does receive that message.

提前加油！

推荐答案

我自己刚刚遇到了这个问题.

Had this problem myself just now.

显然，广播的事件使用QUEUE_DRIVER:

请参阅队列先决条件" :

在广播事件之前，您还需要配置并运行队列侦听器.所有事件广播都是通过排队的作业完成的，因此不会严重影响应用程序的响应时间.

Before broadcasting events, you will also need to configure and run a queue listener. All event broadcasting is done via queued jobs so that the response time of your application is not seriously affected.

因此，要立即捕获事件，可以设置QUEUE_DRIVER=sync.
但这当然是不建议的，因为您的所有其他作业也将同步运行.
因此最好先设置适当的队列处理程序.

So, to catch the events immediately, you could set QUEUE_DRIVER=sync.
But this is of course not advised, since all your other jobs would run in sync as well.
So it's better to set up a proper queue handler first.
