php有微服务架构吗

composer require swoole

<?php
use Swoole\Http\Server;
require __DIR__ . '/vendor/autoload.php';
// 引入自定义的类文件
require_once 'example_service.php';
$server = new Server("0.0.0.0", 9501);
// 设置路由，将请求分发给对应的服务类方法处理
$server->on('request', function ($request, $response) {
    $path = $request->server['path_info'];
    if ($path === '/example') {
        $data = json_decode($request->rawContent(), true);
        $service = new ExampleService();
        $result = call_user_func([$service, $data['method']], ...$data['params']);
        $response->header("Content-Type", "application/json");
        $response->end(json_encode($result));
    } else {
        $response->status(404);
        $response->end();
    }
});
$server->start();

<?php
class ExampleService
{
    public function add(int $a, int $b)
    {
        return $a + $b;
    }
    public function sub(int $a, int $b)
    {
        return $a - $b;
    }
}

<?php
$data = [
    'method' => 'add',
    'params' => [1, 2]
];
