Question

我想知道有多少客户实际订阅了聊天室/会话。

更确切地说，我只想知道是否有超过1个客户端。（聊天室实际上是两个用户之间的私密对话）。

一次只有一个聊天室/私人对话（每个用户）。

那么在给定的代码中，如何获得$ nb_clients？

更新

我想我已经开始看到解决方案了。

这是我的第二次尝试：

class Chat implements WampServerInterface
{
    protected $conversationId;
    public function __construct(){
        $this->conversationId = null;
    }
    public function onSubscribe(ConnectionInterface $conn, $conversation_id){
        $this->conversationId = $conversation_id;
        echo "Client $conn->resourceId assigned to the conversation : $conversation_id\n";
    }
    public function onPublish(ConnectionInterface $conn, $conversation_id, $event, array $exclude, array $eligible){
        // How to get $nb_clients ?
        echo "$nb_clients User(s) in conversation";
        echo "Message sent to $conversation_id : $event";
        // ...
        $message = $event; 
        // Send data to conversation
        $this->conversationId->broadcast($message);
    }
}

任何想法，如果这将正常工作？它实际上似乎工作，但我仍然不确定它是否是最好的解决方案。实际上，我从Ratchet github获得灵感。

Answer 1

onPublish的第二个参数是Topic个对象（Interface WampServerInterface）：

onPublish（Ratchet \ ConnectionInterface $ conn， string | Ratchet \ Wamp \ Topic $ topic，string $ event，array $ exclude，array $符合条件）

所以根据Ratchet's documentation，您可以在主题上使用count()方法来获取订阅者：

$nb_clients = $conversation_id->count();
