Slim 3上傳圖像到服務器路徑

嗨即時通訊新的瘦身3框架（Api爲移動）我想知道如何上傳圖像到服務器，Ë例如沒有找到很多，這是我的代碼但它不起作用。任何幫助將非常感謝。Slim 3上傳圖像到服務器路徑

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

    $files = $request->getUploadedFiles(); 
    if (empty($files['newfile'])) { 
     throw new Exception('Expected a newfile'); 
    } 

    $newfile = $files['newfile']; 


    if ($newfile->getError() === UPLOAD_ERR_OK) { 
    $uploadFileName = $newfile->getClientFilename(); 
    $newfile->moveTo("../photos/"); 
    } 

});

它給了我

你能在什麼_擴大「但它不工作」 _手段的錯誤？另外，也許發佈你試過的完整代碼？（'//用$ newfile做些事情'表明你已經刪除了你的嘗試？） –

檢查錯誤日誌中的實際錯誤消息。您還可以告訴Slim通過以下設置向您顯示實際的錯誤消息：''displayErrorDetails'=> true'，這是您開發時的首選。 –

我休息了這個例子 - > https://akrabat.com/psr-7-file-uploads-in-slim-3/ –

我解決了這樣的

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();
