Laravel事件廣播與socketio和redis不在laravel 5.4中工作？

我試圖顯示用戶登錄到網站時的實時消息通知計數。爲此，我正在使用socketio，redis和laravel事件。但它不起作用。在laravel日誌中，我收到一條消息。在此消息中顯示count，但socket爲空。我想我錯過了什麼。我的gitbash顯示頻道訂閱和用戶連接。Laravel事件廣播與socketio和redis不在laravel 5.4中工作？

Gitbash

[email protected]:~/Code/cabinapi$ node socket.js 
    listening on *:3000 
    Redis: message-channel subscribed 
    a user connected

Laravel登錄

[2017-09-28 07:21:57] local.INFO: Broadcasting [App\Events\MessageEvent] on channels [message-channel] with payload:

{ 
     $count = PrivateMessage::where('receiver_id', new \MongoDB\BSON\ObjectID($id))

      ->count(); 

     if ($count > 0){ 
      event(new MessageEvent($count)); 
     }

你從哪裏得到該日誌？你可以檢查config/broadcasting.php嗎？也許你設置廣播驅動程序登錄那麼.env不工作？ –

@HanlinWang，Log我從storage-> logs-> laravel.log。不，我沒有設置廣播日誌。 ''default'=> env（'BROADCAST_DRIVER'，'null'），' –

我在本地測試了你的代碼，它全部正常工作，而且套接字是空的，這是從你的socket.js'{「事件「：」App \\ Events \\ MessageEvent「，」data「：{」count「：1，」socket「：null}，」socket「：null} '所以你沒有收到像這樣的日誌，對吧？ –

找不到爲什麼它不laravel 5.4工作的確切原因。但我添加了一些更改。現在我正在獲取實時消息通知計數。以下列出了我所做的改變。

我完全做實時通知計數與redis的幫助和socketio

socket.js（Removed ioredis and included redis）

var redis = require('redis'); 
io.on('connection', function(socket){ 
    console.log('a user connected'); 

    var redisClient = redis.createClient(); 
    redisClient.subscribe('message'); 
    redisClient.on('message', function(channel, message){ 
     console.log('new message in queue', channel, message); 
     socket.emit(channel, message); 
    }); 

    socket.on('disconnect', function(){ 
     redisClient.quit(); 
     console.log('user disconnected'); 
    }); 
});

控制器

$redis = Redis::connection(); 
$redis->publish('message', $message);

則須─>所有者 - > layouts-> app.blade.php

<script> 
     var socket = io('{{ env("APP_URL") }}:3000'); 
     socket.on('message-channel:App\\Events\\MessageEvent', function(data){ 
      $('.msgCountRemove').remove(); 
      $('.msgSpan').append('<span class="msgCountRemove">'+data+'</span>'); 
     }); 
    </script>

移除MessageEvent事件。php
