AttributeError：'ZipInfo'对象没有属性'filemode'

Question

如何访问zipfile的filemode属性？

>>> info = zin.infolist()[1]
>>> info
<ZipInfo filename='test_dir/' filemode='drwxr-xr-x' external_attr=0x10>
>>> info.filename
'test_dir/'
>>> info.external_attr
1106051088
>>> info.filemode
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'ZipInfo' object has no attribute 'filemode'

Answer 1

文件属性存储在external_attr的高位（低16位上方）：

oct(1106051088 >> 16)
#'0o40755'

要检查特定权限，请使用模块stat中的功能，例如：

stat.S_ISDIR(1106051088 >> 16)
# True, a directory

stat.S_IRUSR & (1106051088>>16)
# 256, user-readable

stat.S_IWGRP&(1106051088>>16)
# 0, not group-writable
