Android：App不在apache服务器上传视频

Question

我有一个Android应用程序，用户可以在其中拍摄视频，然后单击按钮将视频上传到位于localhost中的名为“Uploads”的文件夹。当我在模拟器上运行应用程序时，一切都按照预期的方式工作。但是当我在一个实际的Android设备上运行时，视频没有上传到我的“上传”文件夹，我得到一个“无法移动文件！”响应。

以下是我用来移动文件的PHP脚本：

<?php

// Path to move uploaded files
$target_path = "Uploads/";

// array for final json respone
$response = array();

// getting server ip address
$server_ip = gethostbyname(gethostname());

// final file url that is being uploaded
$file_upload_url = 'http://' . $server_ip . '/' . 'UploadedVideos' . '/' . $target_path;
chmod($_SERVER['DOCUMENT_ROOT'] . '/' . 'UploadedVideos' . '/' . 'Uploads', 0777);

if (isset($_FILES['video']['name'])) {
    $target_path = $target_path . basename($_FILES['video']['name']

    try {
 // Throws exception incase file is not being moved

  if (!move_uploaded_file($_FILES['video']['tmp_name'], $target_path)) {
   // make error flag true
   $response['error'] = true;
   $response['message'] = 'Could not move the file!';
  } else {

    // File successfully uploaded
    $response['message'] = 'File uploaded successfully!';
    $response['error'] = false;

    $response['file_path'] = $file_upload_url . basename($_FILES['video']['name']);
  }
 } catch (Exception $e) {
   // Exception occurred. Make error flag true
   $response['error'] = true;
   $response['message'] = $e->getMessage();
 }
} else {
 // File parameter is missing
 $response['error'] = true;
 $response['message'] = 'Not received any file!F';
}

// Echo final json response to client
echo json_encode($response);
?>

我认为这与Windows 8.1上的“上传”文件夹写权限有关，所以我问你：如何从文件夹中获取写入权限才能从Android设备访问？
