Question

有些用户上传了保密合同/协议文件，这些文件存储在/var/www/html/project/public/contract/<HERE_UNIQUE_FILES.pdf>目录中。

但问题是来自谷歌搜索或直接链接，任何未经授权的用户都可以打开它并查看/复制它。

我如何保护它，以便只有我的域或允许的对等体才能访问此私人目录？

示例：

class Application_Model_Uploader
{

  public static function mvUploadContract()
  {     
        /* Anyone from outside can access this path, but how to protect it? */
        $target_path = APPLICATION_PATH . "/../public/contract/";          
        $target_path = $target_path .  basename( $_FILES['contractfile']['name']);
        if(move_uploaded_file($_FILES['contractfile']['tmp_name'], $target_path)) 
        {
            $result = true;
        }else{
            $result = false;
        }
  }
}

将文件移出公共目录，并在授权用户后使用PHP对其进行流式传输。

if (is_authorized($user)) {
  header('Content-Description: File Transfer');
  header('Content-Type: application/octet-stream');
  header('Content-Disposition: attachment; filename='.basename($path_to_file_outside_public));
  header('Content-Transfer-Encoding: binary');
  header('Expires: 0');
  header('Cache-Control: must-revalidate');
  header('Pragma: public');
  header('Content-Length: ' . filesize($path_to_file_outside_public));

  readfile($path_to_file_outside_public);
}
