如何使用Python而不使用pywin32来确定Windows上的文件所有者

我正在写一个脚本，需要确定窗口上文件的所有者的用户名。

虽然我发现了一个使用pywin32的解决scheme，但我犹豫不决，因为我不想添加模块依赖。

该脚本将为python 2.6编写，并且必须在32位和64位平台上运行。

我想知道是否有不同的方法，可能与ctypes，来确定这个信息

下面的示例使用ctypes访问问题中链接的代码段中的WinAPI函数。

ctypes的定义

函数定义

if __name__ == '__main__': import sys filename = sys.argv[1] if isinstance(filename,bytes): filename = filename.decode('mbcs') name,sid_type = get_file_owner(filename) if domain: name = '{0}\{1}'.format(domain,name) print("File : {0}".format(filename)) print("Owner: {0} ({1})".format(name,sid_type))

你可以调用一个windows shell命令“dir / q”并解析输出以找到所有者。

subprocess.call("dir /q",shell=True)
