from zipfile import ZipFile


fzip=ZipFile("crackme.zip")
fzip.extractall(pwd=b"mysecretpassword")

该脚本仅适用于 IDLE,但是当我从命令行运行它时,它显示:

解压.py

fzip.extractall(pwd=b"mysecretpassword")

                              ^

SyntaxError:无效的语法

怎么了?

它可以工作(Ubuntu 13.04):

>>> import sys
>>> sys.version
'3.3.1 (default, Apr 17 2013, 22:32:14) \n[GCC 4.7.3]'

>>> from zipfile import ZipFile
>>> f = ZipFile('a.zip')

顺便说一句,pwd应该是字节对象:

>>> f.extractall(pwd="mysecretpassword")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.3/zipfile.py", line 1225, in extractall
    self.extract(zipinfo, path, pwd)
  File "/usr/lib/python3.3/zipfile.py", line 1213, in extract
    return self._extract_member(member, path, pwd)
  File "/usr/lib/python3.3/zipfile.py", line 1275, in _extract_member
    with self.open(member, pwd=pwd) as source, \
  File "/usr/lib/python3.3/zipfile.py", line 1114, in open
    raise TypeError("pwd: expected bytes, got %s" % type(pwd))
TypeError: pwd: expected bytes, got <class 'str'>
>>> f.extractall(pwd=b'mysecretpassword')
>>>

根据zipfile.ZipFile.extractall文件

警告未经事先检查,切勿从不受信任的来源提取档案。文件可能是在路径之外创建的,例如具有以“/”开头的绝对文件名或带有两个点“..”的文件名的成员。

在 3.3.1 版更改: zipfile 模块试图阻止这种情况。见extract()注。
