PHPサーバーにAndroidデバイスからファイルをアップロードしています

AndroidデバイスからPHPサーバーにファイルをアップロードしようとしていますが、サーバーがファイルを受信して​​いません。これが私のサンプルコードです。オンラインで見つけました。 phpサーバー、私はチャンクを介してファイルをアップロードしています

PHPサービス:

  $file_path = "images/";
  $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);

  if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
  echo "success";
  } else{ echo "fail";}

サーバーに「イメージ」フォルダーを作成する必要があります

無料ホスティングを使用している場合、ページはトラッキングなしにリダイレクトされます。ヒットの。おそらくHttp Response:200 OKを受信しますが、ファイルが失われるため、アップロードされたファイルは表示されません。

私自身、解決策を探して3日間無駄にしたが、何も見つかりませんでした。これを自分で考え出した。
