如何使用python获取文件的扩展MacOS属性? [英] How to get extended MacOS attributes of a file using python?

问题描述

我有兴趣使用python从文件中获取更多信息.

I'm interested in getting more information from a file using python.

我知道使用os.stat(例如下面的代码)会返回文件信息，但是我想从文件中获取其他属性，例如来自哪里?"

I know that using os.stat (such as below) returns information on the file, but I'd like to get other attributes from the file such as 'Where from?'

os.stat(filename)

posix.stat_result(st_mode=33184, st_ino=131691855, st_dev=16777220L, st_nlink=1, st_uid=501, st_gid=20, st_size=174241, st_atime=1445046864, st_mtime=1445045836, st_ctime=1445045836)

但是，这些不是我感兴趣的属性.我有兴趣获取以下所有属性(尤其是来自哪里")

However, these aren't the attributes I'm interested. I'm interested in getting all of the below attributes (in particular 'Where from')

如何获取来源"字段?

我尝试使用os.access，但是没有返回我想要的，并且一直在搜索 OS上的文档，所以我不确定我还能尝试什么.

I've tried using os.access, but that doesn't return what I want, and have been searching the documentation on os, so I'm not sure what else I can try.

看起来好像有一个名为xattr的程序包看起来不错..(您需要pip install xattr它)

looks like there is a package called xattr doesnt look bad.. (you need to pip install xattr it)

In [6]: import xattr
In [7]: x = xattr.xattr('/Users/buzzi/Projects/apimon/apimon/check/tests/resources/brus->lux dec 28.pdf')

In [8]: x.items()
Out[8]: 
[(u'com.apple.metadata:kMDItemWhereFroms',
  'bplist00\xa2\x01\x02_\x10Thttps://be-internet.bene-system.com//hp/pdfservice?pdf=KLWVWLG1445013390236BS169201P\x08\x0bb\x00\x00\x00\x00\x00\x00\x01\x01\x00\x00\x00\x00\x00\x00\x00\x03\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00c'),
 (u'com.apple.quarantine',
  '0001;562127d1;Google Chrome;BF24C900-46D5-4F95-9B7B-C36AA6B0ACC7')]

更多研究使我进入了biplist模块. (您需要pip install biplist它)

More research lead me to biplist module. (you need to pip install biplist it)

>>> import biplist
>>> biplist.readPlistFromString(x.get('com.apple.metadata:kMDItemWhereFroms'))
['https://be-internet.bene-system.com//hp/pdfservice?pdf=KLWVWLG1445013390236BS169201',
 '']
