gibt gelöst Ich mag dieses

use \Psr\Http\Message\ServerRequestInterface as Request; 
use \Psr\Http\Message\ResponseInterface as Response; 
use Slim\Http\UploadedFile; 

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

$app = new \Slim\App([ 
'settings' => [ 
    'displayErrorDetails' => true 
] 
    ]); 



$container = $app->getContainer(); 
$container['upload_directory'] ='../photos/'; 

$app->post('/photo', function (Request $request, Response $response) use ($app) { 

$directory = $this->get('upload_directory'); 

$uploadedFiles = $request->getUploadedFiles(); 

$uploadedFile = $uploadedFiles['picture']; 
    if($uploadedFile->getError() === UPLOAD_ERR_OK) { 
    $filename = moveUploadedFile($directory, $uploadedFile); 
    $response->write('uploaded ' . $filename . '<br/>'); 
} 

}); 


function moveUploadedFile($directory, UploadedFile $uploadedFile){ 
$extension = pathinfo($uploadedFile->getClientFilename(), 
PATHINFO_EXTENSION); 
$basename = bin2hex(random_bytes(8)); 
$filename = sprintf('%s.%0.8s', $basename, $extension); 
$uploadedFile->moveTo($directory . DIRECTORY_SEPARATOR . $filename); 

return $filename; 
} 


$app->run();
