【问题描述】：

您好，我是 slim 3 框架（移动 Api）中的新成员非常感谢。

  $app->post('/photo', function ($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/");
   }

 });

它给我的错误

【问题讨论】：

您能否详细说明“但它不起作用” 的含义？另外，也许发布您尝试过的完整代码？（// do something with $newfile 表明您已删除您的尝试？）
检查错误日志以获取实际的错误消息。你也可以告诉 Slim 显示实际的错误信息，设置为：'displayErrorDetails' => true，这是你开发时的首选。
我不喜欢这个例子 -> akrabat.com/psr-7-file-uploads-in-slim-3
我们仍然需要查看实际的错误信息。请按照上面的建议打开displayErrorDetails，然后重试。顺便说一句，您是否在$newfile->moveTo("/path/to/$uploadFileName") 通话中更改了/path/to/？这需要在您的服务器上设置为绝对路径，您的 PHP 代码在其中具有写入权限。
好的，我更新了问题，但是有什么例子我应该休息一下吗？

【解决方案1】：

我是这样解决的

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();
