Angularjs 使用Socket.io Redis服务器正确发送通知

目标：将帖子添加到特定频道时，向该频道的所有已连接订阅用户发送通知

视图上的关系数据库表：Post、通道、用户、通道\用户

• 帖子：id、标题、内容、频道\ id（指出帖子与哪个频道相关）
• 频道：id、名称（频道列表）
• 用户：id、用户名（用户表）
• 频道用户：id、频道id、用户id（此表指示用户订阅的频道。）

目标：创建帖子时，向特定用户组发送通知

我已经尝试了几种方法，它正在发挥作用。但我正在寻找正确的方法

服务器端：socket.js

在创建新帖子时将数据发布到Redis服务器

 $data = [
        'event' => 'newPost',
        'data'  => [
            'title'      => $postTitle,
            'content'    => $postContent
        ]
    ];

    $redisChannel = "channel-" . $channelId;  // As per our naming conventions
    Redis::publish($redisChannel, json_encode($data));

用户正在正确获得他们已订阅的频道的通知

问题1：我不确定这是实现此通知的最佳解决方案

问题2：当用户在多个浏览器选项卡中打开同一应用程序时，会收到所有这些选项卡的通知。它应该只发送一个通知。这与redis端服务器端的用户管理有关。这部分我也不太清楚

我非常感谢你在这方面的建议/帮助。先谢谢你
