Question

我有以下代码：

/routes/web.php

<?php

use App\Events\UserSignedUp;

Route::get('/', function () {
    $data = [
        'event' => 'UserSignedUp',
        'data' => [
            'username' => 'JohnDoe'
        ]
    ];
    //Redis::publish('test-channel', json_encode($data));
    event(new UserSignedUp('JohnDoe'));
    return view('welcome');
});

我正在使用的功能：event(...)。

我还有以下Event文件：

/app/Events/UserSignedUp.php

<?php

namespace App\Events;

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;

class UserSignedUp implements ShouldBroadcast
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    public $username;

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

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return new Channel('test-channel');
    }

}

然后，我正在Node.js文件上监听事件：

/socket.js

var server = require('http').Server();
var io = require('socket.io')(server);
var Redis = require('ioredis');
var port = process.env.PORT || 3000;

var redis = new Redis();

redis.subscribe('test-channel');

redis.on('message', function(channel, message) {
    console.log(channel, message);
});

server.listen(port, function(){
    console.log('listening on *:' + port);
});

我的问题是，在上面的文件中： /routes/web.php ，我使用：

event(new UserSignedUp('JohnDoe'));

事件未到达Node.js侦听器。但是，该事件已正确到达Redis，因为我可以使用$ redis-cli monitor命令看到它。

[编辑1] 以下是调用event(...)函数时得到的内容：

1541489387.307573 [0 127.0.0.1:52109] "SELECT" "0"
1541489387.308379 [0 127.0.0.1:52109] "RPUSH" "queues:default" "{\"displayName\":\"App\\\\Events\\\\UserSignedUp\",\"job\":\"Illuminate\\\\Queue\\\\CallQueuedHandler@call\",\"maxTries\":null,\"timeout\":null,\"timeoutAt\":null,\"data\":{\"commandName\":\"Illuminate\\\\Broadcasting\\\\BroadcastEvent\",\"command\":\"O:38:\\\"Illuminate\\\\Broadcasting\\\\BroadcastEvent\\\":7:{s:5:\\\"event\\\";O:23:\\\"App\\\\Events\\\\UserSignedUp\\\":2:{s:8:\\\"username\\\";N;s:6:\\\"socket\\\";N;}s:10:\\\"connection\\\";N;s:5:\\\"queue\\\";N;s:15:\\\"chainConnection\\\";N;s:10:\\\"chainQueue\\\";N;s:5:\\\"delay\\\";N;s:7:\\\"chained\\\";a:0:{}}\"},\"id\":\"7CjGqwcRXoZhVIJyFU8AcQ5aTW8G6Cke\",\"attempts\":0}"

另一方面，当我使用时：

Redis::publish('test-channel', json_encode($data));

事件正确到达Node.js侦听器。

[编辑2] 以下是调用Redis::publish(...)函数时得到的内容：

1541489590.930114 [0 127.0.0.1:52124] "SELECT" "0"
1541489590.930872 [0 127.0.0.1:52124] "PUBLISH" "test-channel" "{\"event\":\"UserSignedUp\",\"data\":{\"username\":\"JohnDoe\"}}"

关于为什么事件没有到达Node.js侦听器事件的任何想法是什么？

谢谢。

Laravel函数“事件”在广播事件时不起作用
