php - slim框架如何获得query参数？

Question

在slim框架中：

<?phpnamespace Test\SDK\Sample;require __DIR__ . '/../vendor/autoload.php';use Psr\Http\Message\ResponseInterface as Response;use Psr\Http\Message\ServerRequestInterface as Request;use Slim\Factory\AppFactory;$app = AppFactory::create();$app->get('/hello/{name}', function (Request $request, Response $response, array $args) {    $name = $args['name'];    $response->getBody()->write("Hello, $name");    return $response;});

我们可以访问：
http://localhost:8080/hello/bob

请问如何在slim获得query参数呢，比如访问：

http://localhost:8080/hello/bob?aaa=111&bbb=222

搜索无结果。

可通过如下方式获取：

<?phpnamespace Test\SDK\Sample;require __DIR__ . '/../vendor/autoload.php';use Psr\Http\Message\ResponseInterface as Response;use Psr\Http\Message\ServerRequestInterface as Request;use Slim\Factory\AppFactory;$app = AppFactory::create();$app->get('/hello/{name}', function (Request $request, Response $response, array $args) {    // 获取路径参数    $name = $args['name'];        // 获取查询参数    $queryParams = $request->getQueryParams();        // 获取特定的查询参数    $aaa = isset($queryParams['aaa']) ? $queryParams['aaa'] : null;    $bbb = isset($queryParams['bbb']) ? $queryParams['bbb'] : null;        // 构建响应字符串    $greeting = "Hello, $name";    if ($aaa !== null && $bbb !== null) {        $greeting .= " - aaa: $aaa, bbb: $bbb";    }        // 将响应写入响应体    $response->getBody()->write($greeting);    return $response;});$app->run();
