使用棘轮 php 将消息推送到 websockets 而没有 ZeroMQ答案

【问题标题】：Push message to websockets with ratchet php and without ZeroMQ使用棘轮 php 将消息推送到 websockets 而没有 ZeroMQ

【问题描述】：

我尝试用棘轮和棘爪制作 websocket 服务器。我用 ZeroMQ http://socketo.me/docs/push 阅读了文档棘轮但不能用 Pawl https://github.com/ratchetphp/Pawl 运行它

我创建客户端：

<script>
    var ws = new WebSocket('ws://site.ll:8008/?user=tester01');
    ws.onmessage = function(evt) { console.log(evt.data); };
</script>

创建工人：

require __DIR__ . '/vendor/autoload.php';
require __DIR__ . '/Pusher.php';

$loop   = React\EventLoop\Factory::create();
$pusher = new Pusher;

// Set up our WebSocket server for clients wanting real-time updates
$webSock = new React\Socket\Server('0.0.0.0:8008', $loop);

$webServer = new Ratchet\Server\IoServer(
    new Ratchet\Http\HttpServer(
        new Ratchet\WebSocket\WsServer(
            new Ratchet\Wamp\WampServer(
                $pusher
            )
        )
    ),
    $webSock
);

$loop->run();

Pusher 类的用法与教程http://socketo.me/docs/push#zeromq_messages中的一样

使用post.php通过ws发送消息：

$localsocket = 'tcp://127.0.0.1:1235';
$user = 'tester01';
$message = 'test';

$instance = stream_socket_client($localsocket);
fwrite($instance, json_encode(['user' => $user, 'message' => $message])  . "\n");

但是还是不明白如何在没有 ZeroMQ 的情况下创建 tcp 服务器，比如这部分：

$context = new React\ZMQ\Context($loop);
$pull = $context->getSocket(ZMQ::SOCKET_PULL);
$pull->bind('tcp://127.0.0.1:1235');
$pull->on('message', array($pusher, 'onBlogEntry'));

【解决方案1】：

如果你不想使用 ZeroMQ，你可以使用与 Ratchet 相同的 React 机制。

require __DIR__ . '/vendor/autoload.php';
require __DIR__ . '/Pusher.php';

use React\EventLoop\Factory;
use React\Socket\ConnectionInterface;
use React\Socket\Server;

$loop   = Factory::create();
$pusher = new Pusher;

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

// Set up an incoming TCP socket to receive the messages to push
$inSocket = new Server('127.0.0.1:5555', $loop);
$inSocket->on('connection', function (ConnectionInterface $conn) use ($pusher) {
    // New data arrives at the socket
    $conn->on('data', function ($data) use ($conn, $pusher) {
        // Push the new blog entry update
        $pusher->onBlogEntry($data);
        // Close the incoming connection when the message is consumed
        $conn->close();
    });
});

$loop->run();

接下来使用 Pawl 并在 github 上加载： https://github.com/Shkarbatov/WebSocketPHPRatchet
