php - SOCKET_PUSH 不使用 ZMQContext 发送任何内容？ [被防火墙阻止...]

Question

我正在尝试按照本教程进行 Ratchet/ZMQ 套接字编程:
http://socketo.me/docs/push

通过一些自定义来了解更多关于它的信息。

服务器本身运行良好，前端 html 之间的连接似乎连接正确。但我无法确定向服务器发送消息的 PHP 文件。

以下代码:

SENDER.PHP

$context    = new ZMQContext();
$socket     = $context->getSocket(ZMQ::SOCKET_PUSH,'my pusher');
$socket->connect('tcp://127.0.0.1:5555');
$socket->send("SENDING A MESSAGE");

上面的代码是我遇到的问题。当我在命令行中运行代码时
php sender.php
服务器至少应该显示一些反馈，但它没有给我任何东西。而sender.php 刚刚退出。
我一直试图弄清楚我错过了什么。至少 front-html 位有效。
如何让 sender.php 发送消息？任何建议/建议/帮助将不胜感激。

以下是我的其余代码:

INDEX.html

这个 html 文件正在连接，因为我从构造函数获取消息。

ab.debug(true,true);
var conn = new ab.Session('ws://localhost:8080',
        function() {
            conn.subscribe('kittensCategory', function(data) {
                // This is where you would add the new article to the DOM (beyond the scope of this tutorial)
                console.log("New data available: ",data);
            });
        },
        function() {
            console.warn('WebSocket connection closed');
        },
        {'skipSubprotocolCheck': true}
);

SERVER.PHP

use Models\SCSTRealtimeSubsObject;

// The event loop that will keep on triggering
$loop   = React\EventLoop\Factory::create();

// Our custom pusher that will do the logic, $loop is optional
$pusher =  new SCSTRealtimeSubsObject;

// Listen for the web server to make a ZeroMQ push after an ajax request
$context = new React\ZMQ\Context($loop);
$pull = $context->getSocket(ZMQ::SOCKET_PULL);
//Binding to itself means the client can only connect to itself
$pull->bind("tcp://127.0.0.1:5555");
//On a 'message' event, pass the data to the myMessageHandler method of the MyPusherClass
$pull->on('message', array($pusher, 'customAction'));

// Set up our WebSocket server for clients wanting real-time updates
$webSock = new React\Socket\Server('0.0.0.0:8080', $loop); // Binding to 0.0.0.0 means remotes can connect
$webServer = new Ratchet\Server\IoServer(
    new Ratchet\Http\HttpServer(
        new Ratchet\WebSocket\WsServer(
            new Ratchet\Wamp\WampServer(
                $pusher
            )
        )
    ),
    $webSock
);

$loop->run();

PUSHER.PHP

class SCSTRealtimeSubsObject implements WampServerInterface {

    public function __construct() {
        echo "Constructor call. \n";
    }
    public function customAction($msg){ // Message from the onMessage
        echo "There was a message: $msg";

    public function onOpen(ConnectionInterface $conn) {
        echo "New connection! ({$conn->resourceId}) \n";
    }
    public function onClose(ConnectionInterface $conn) {
        // The connection is closed, remove it, as we can no longer send it messages
        echo "Connection {$conn->resourceId} has disconnected \n";
    }
    public function onError(ConnectionInterface $conn, \Exception $e) {
        echo "There is an error ". $e->getMessage();

        echo "New subscriber : $topic \n";
    }
    public function onUnSubscribe(ConnectionInterface $conn, $topic) {
        echo "Unsubscribed : $topic \n";
    }
    public function onCall(ConnectionInterface $conn, $id, $topic, array $params) {
        // In this application if clients send data it's because the user hacked around in console
        $conn->callError($id, $topic, 'You are not allowed to make calls')->close();
    }
    public function onPublish(ConnectionInterface $conn, $topic, $event, array $exclude, array $eligible) {
        // In this application if clients send data it's because the user hacked around in console
        echo "Published $topic. \n";
        $conn->close();
    }
}

Answer 1

终于找到了答案。我忘了附上我的开发服务器在 Windows 上。

就我而言，php cli 受 Windows 防火墙限制，无法访问任何网络和端口。

要解决此问题，请转到控制面板 -> Windows 防火墙。查找入站 CLI，这很可能是 PhP exe。允许访问网络，这应该可以解决问题。
