Slim-PHP：如何将数组合并到 slim 请求中

Question

我正在 Slim 框架中创建一个用于 XSS 保护的中间件。 这是我的代码：

$input = $request->getParsedBody();
    array_walk_recursive($input, function(&$input) {
        $input = htmlspecialchars($input);
    });
    $request->merge($input); // Not able to merge $input into $request

    return $next($request, $response, $next);

清理请求后，我想合并到 slim http 请求中，这样当我使用 $request->getParsedBody() 时，我应该获得清理数据。

Answer 1

use Slim\Factory\AppFactory;
use Psr\Http\Message\ServerRequestInterface as Request;
use Psr\Http\Server\RequestHandlerInterface as RequestHandler;
use Slim\Psr7\Response;

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

$app = AppFactory::create();

$app->post('/merge-array', function (Request $request, Response $response, $args) {
    // Get the current request body
    $body = $request->getParsedBody();
    
    // Your array to merge into the request body
    $newData = [
        'key1' => 'value1',
        'key2' => 'value2',
    ];

    // Merge the new data with the existing request body
    $mergedBody = array_merge($body, $newData);

    // Create a new request with the merged body
    $newRequest = $request->withParsedBody($mergedBody);

    // Forward the new request to the next middleware or route handler
    return $handler->handle($newRequest);
});

$app->run();
