如何使用PHP和SOAP实现异步通信和消息队列

<?php
require_once('lib/nusoap.php');

$server = new soap_server();
$server->configureWSDL('AsyncServer', 'urn:AsyncServer');

function my_async_function($parameter)
{
    // 需要执行的异步操作代码
    // ...

    return 'success';
}

$server->register('my_async_function',
    array('parameter' => 'xsd:string'),
    array('return' => 'xsd:string'),
    'urn:AsyncServer',
    'urn:AsyncServer#my_async_function',
    'rpc',
    'encoded',
    'My async function');

$server->service(file_get_contents('php://input'));
?>

<?php
require_once('lib/nusoap.php');

$client = new nusoap_client('http://localhost/async_server.php?wsdl', 'wsdl');

$response = $client->call('my_async_function', array('parameter' => 'hello'));

print_r($response);
?>

<?php
require_once('vendor/autoload.php');

use PhpAmqpLibConnectionAMQPStreamConnection;
use PhpAmqpLibMessageAMQPMessage;

$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();

$queue = 'async_queue';
$channel->queue_declare($queue, false, true, false, false);

$message = new AMQPMessage('Hello, message!');

$channel->basic_publish($message, '', $queue);

$channel->close();
$connection->close();
?>

<?php
require_once('vendor/autoload.php');

use PhpAmqpLibConnectionAMQPStreamConnection;

$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();

$queue = 'async_queue';
$channel->queue_declare($queue, false, true, false, false);

$channel->basic_consume($queue, '', false, false, false, false, function ($msg) {
    echo "Received: " . $msg->body . "
";
    $msg->ack();
});

while ($channel->is_consuming()) {
    $channel->wait();
}

$channel->close();
$connection->close();
?>
