我刚刚为 Ratchet WAMP + autobahn 版本 1 制作了一个聊天 hello world。
如果您想查看完整的源代码,请点击此处

JavaScript 客户端发送聊天消息:

           function click_send_btn() {
                 var json_data = {
                    "message": $.trim($("#input_message").val())
                 };
            sess.publish("send_message", json_data, true);
            }

PHP Ratchet 服务器发布消息:

public function onPublish(\Ratchet\ConnectionInterface $conn, $topic, $event, array $exclude, array $eligible) {
    switch ($topic) {
        case 'http://localhost/enter_room':
            $foundChater = $this->allChater[$conn];
            $newChaterName = $event['username'];
            $foundChater->setChatName($newChaterName);
            break;
        case 'send_message':
            $foundChater = $this->allChater[$conn];
            $event['username']=$foundChater->getChatName();
            break;
    }
    $topic->broadcast($event);
    echo "onPublish {$conn->resourceId}\n";
}

在此处输入图像描述

我不明白为什么用 excludeme 发布不起作用。
在上面2个firefox,对firefox说:我是吧。该消息不应该显示在他自己身上,但确实如此。

我刚刚修好了。
我真是个傻瓜。我没有处理参数“array $exclude”
,我还使用了 $topic->broadcast($event) 来强制向所有人广播。
现在我创建一个函数

/**
 * check whitelist and blacklist
 * 
 * @param array of sessionId $exclude -- blacklist
 * @param array of sessionId $eligible -- whitelist
 * @return array of \Ratchet\ConnectionInterface
 */
private function getPublishFinalList(array $exclude, array $eligible) {
    //array of sessionId
    $allSessionId = array();
    $this->allChater->rewind();
    while ($this->allChater->valid()) {
        array_push($allSessionId, $this->allChater->current()->WAMP->sessionId);
        $this->allChater->next();
    }

    //if whitelist exist, use whitelist to filter
    if (count($eligible) > 0) {
        $allSessionId = array_intersect($allSessionId, $eligible);
    }

    //then if blacklist exist, use blacklist to filter
    if (count($exclude) > 0) {
        $allSessionId = array_diff($allSessionId, $exclude);
    }

    //return array of connection        
    $result = array();
    $this->allChater->rewind();
    while ($this->allChater->valid()) {
        $currentConn = $this->allChater->current();
        if (in_array($currentConn->WAMP->sessionId, $allSessionId)) {
            array_push($result, $currentConn);
        }
        $this->allChater->next();
    }
    return $result;
}

在 onPublish 中,我不再使用 $topic->broadcast($event) 了。

    $conn2PublishArray = $this->getPublishFinalList($exclude, $eligible);
    foreach ($conn2PublishArray as $conn2Publish) {
        $conn2Publish->event($topic, $new_event);
    }    

连接类有一个方法'even',可以直接向'subscriber'发送消息。
