php stomp消息怎样处理-乐工具技术知识

要处理PHP STOMP消息，您需要遵循以下步骤：

安装STOMP库：首先，确保您的PHP环境中已安装stomp.php库。您可以使用Composer进行安装：

composer require cboden/ratchet

创建一个WebSocket服务器：接下来，创建一个WebSocket服务器以便与STOMP客户端通信。这里是一个简单的例子：

// server.php
require 'vendor/autoload.php';

use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\StompHandler;

$server = IoServer::factory(
    new HttpServer(
        new WsServer(
            new StompHandler()
        )
    ),
    8080
);

$server->run();

创建一个STOMP处理器：现在，我们需要创建一个处理器来处理传入的STOMP消息。在这个例子中，我们将简单地将接收到的消息原样返回：

// MyApp/StompHandler.php
namespace MyApp;

use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
use Stomp\Client as StompClient;

class StompHandler implements MessageComponentInterface {
    protected $clients;

    public function __construct() {
        $this->clients = new \SplObjectStorage;
    }

    public function onOpen(ConnectionInterface $conn) {
        $this->clients->attach($conn);
    }

    public function onClose(ConnectionInterface $conn) {
        $this->clients->detach($conn);
    }

    public function onError(ConnectionInterface $conn, \Exception $e) {
        echo "An error has occurred: {$e->getMessage()}\n";
        $conn->close();
    }

    public function onMessage(ConnectionInterface $from, $msg) {
        foreach ($this->clients as $client) {
            if ($from !== $client) {
                $client->send($msg);
            }
        }
    }
}

运行WebSocket服务器：最后，运行WebSocket服务器以侦听传入的STOMP连接：

php server.php

现在，您可以使用STOMP客户端连接到WebSocket服务器并发送/接收消息。这是一个简单的STOMP客户端示例：

// stomp_client.php
require 'vendor/autoload.php';

use Stomp\Client;

$client = new Client('ws://localhost:8080');

$client->connect();

$client->subscribe('/topic/my_topic', function ($message) {
    echo "Received message: {$message->body}\n";
});

$client->send('/topic/my_topic', '', 'Hello, World!');

sleep(10);

$client->disconnect();

运行此客户端以发送消息到STOMP服务器，服务器将把消息广播给所有订阅了该主题的其他客户端。
