android - Cakephpを使用してAndroidからサーバーに画像をアップロードする

Question

サーバーに画像をアップロードできるAndroidアプリを作成しています(Cakephpを使用)。私はこのソリューションのような純粋な php で行うことができます: Upload image from android to cakephp server 私の問題は、コントローラーを処理してファイルを Cakephp の img ディレクトリに移動する方法がわからないことです。私はすでに以下のコードを使用しようとしていますが、うまくいきません。アシスタントには本当に感謝しています。

$target_path  = "./";
$target_path = $target_path . basename( $_FILES['picture']['name']);
if(move_uploaded_file($_FILES['picture']['tmp_name'], $target_path)) {
 echo "The file ".  basename( $_FILES['picture']['name']).
 " has been uploaded";
} else{
 echo "There was an error uploading the file, please try again!";
}

これはアンドロイドのコードです

try {

            // open a URL connection to the Server
            FileInputStream fileInputStream = new FileInputStream(newFile);
            URL url = new URL(url_upload);

            // Open a HTTP connection to the URL
            conn = (HttpURLConnection) url.openConnection();
            conn.setDoInput(true); // Allow Inputs
            conn.setDoOutput(true); // Allow Outputs
            conn.setUseCaches(false); // Don't use a Cached Copy
            conn.setRequestMethod("POST");
            conn.setRequestProperty("Connection", "Keep-Alive");
            conn.setRequestProperty("ENCTYPE", "multipart/form-data");
            conn.setRequestProperty("Content-Type",
                    "multipart/form-data;boundary=" + boundary);
            conn.setRequestProperty("profilepicture",
                    newFile.getAbsolutePath());

            dos = new DataOutputStream(conn.getOutputStream());

            dos.writeBytes(twoHyphens + boundary + lineEnd);
            dos.writeBytes(("Content-Disposition: form-data; name=\"picture\";filename=\""
                    + newFile.getAbsolutePath() + "\"" + lineEnd));

            dos.writeBytes(lineEnd);

            // create a buffer of maximum size
            bytesAvailable = fileInputStream.available();

            bufferSize = Math.min(bytesAvailable, maxBufferSize);
            buffer = new byte[bufferSize];

            // read file and write it into form...
            bytesRead = fileInputStream.read(buffer, 0, bufferSize);

            while (bytesRead > 0) {

                dos.write(buffer, 0, bufferSize);
                bytesAvailable = fileInputStream.available();
                bufferSize = Math.min(bytesAvailable, maxBufferSize);
                bytesRead = fileInputStream.read(buffer, 0, bufferSize);

            }

            // send multiple part form data necessary after file data...
            dos.writeBytes(lineEnd);
            dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

            // Responses from the server (code and message)
            serverResponseCode = conn.getResponseCode();
            String serverResponseMessage = conn.getResponseMessage();

            if (serverResponseCode == 200) {

                Log.i("uploadFile", "HTTP Response is : "
                        + serverResponseMessage + ": " + serverResponseCode);
            }
            // after download show image in gallery
            context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
                    Uri.parse("file://"
                            + Environment.getExternalStorageDirectory())));

            // close the streams //
            fileInputStream.close();
            dos.flush();
            dos.close();

        } catch (MalformedURLException ex) {

            ex.printStackTrace();
            Log.e("Upload file to server", "error: " + ex.getMessage(), ex);

        } catch (Exception e) {
            e.printStackTrace();
            Log.e("Upload file to server Exception",
                    "Exception : " + e.getMessage(), e);
        }
