从Python调用FSCTL_CREATE_OR_GET_OBJECT_ID

我试图让Python的备份程序中使用NTFS对象ID。 我在我的头上，但设法创build一个函数返回…的东西。

import sys import win32file import winioctlcon def object_id(filename): """ NTFS OBJECT_ID """ fhandle = win32file.CreateFileW( # FileName filename, # DesiredAccess win32file.GENERIC_READ, # ShareMode win32file.FILE_SHARE_READ | win32file.FILE_SHARE_WRITE, # SecurityAttributes None, # CreationDisposition win32file.OPEN_EXISTING, # FlagsAndAttributes 0 ) obj_id = win32file.DeviceIoControl( # Device : PyHANDLE # Handle to a file, device, or volume fhandle, # IoControlCode : int # IOControl Code to use, from winioctlcon winioctlcon.FSCTL_CREATE_OR_GET_OBJECT_ID, # InBuffer : str/buffer # The input data for the operation, can be None for some operations. None, # OutBuffer : int/buffer # Size of the buffer to allocate for output, or a writeable buffer as # returned by win32file::AllocateReadBuffer. 64, # Overlapped=None : PyOVERLAPPED An overlapped object for async # operations. Device handle must have been opened with # FILE_FLAG_OVERLAPPED. None ) fhandle.Close() return obj_id 

调用此函数的一些示例输出是一个类似于“↑∟k◄◄êê％d d d d d M / / /╧╧╧╧d d d str str str str str str str str str str”。 这对我的程序来说是很好的，只要它对我备份的每个文件都是一致的。 但是我在这里做了什么可怕的错误？ 理想情况下，我想尽可能正确地实现这一点。
