Python zipfile 模块错误地认为我有一个跨越多个磁盘的 zipfile，抛出 BadZipfile 错误 [英] Python zipfile module erroneously thinks I have a zipfile that spans multiple disks, throws BadZipfile error

问题描述

我有一个 1.4GB 的 zip 文件，我正在尝试依次让每个成员产生.zipfile 模块不断抛出 BadZipfile 异常，说明

I have a 1.4GB zip file and am trying to yield each member in succession. The zipfile module keeps throwing a BadZipfile exception, stating that

zipfile.BadZipfile:不支持跨越多个磁盘的 zipfile".

"zipfile.BadZipfile: zipfiles that span multiple disks are not supported".

这是我的代码:

import zipfile

def iterate_members(zip_file_like_object):
  zflo = zip_file_like_object
  assert zipfile.is_zipfile(zflo) # Here is where the error happens.
  # If I comment out the assert, the same error gets thrown on this next line:
  with zipfile.ZipFile(zflo) as zip:
    members = zip.namelist()
    for member in members:
      yield member

fn = "filename.zip"
iterate_members(open(fn, 'rb'))

我使用的是 Python 2.7.3.我在 Windows 8 和 ubuntu 上都尝试过，结果相同.非常感谢任何帮助.

I'm using Python 2.7.3. I tried on both Windows 8 and ubuntu with the same result. Any help very much appreciated.

推荐答案

尽管我使用的是 python 3.4，但我在类似文件上遇到了同样的错误

I get the same error on a similar file although I am using python 3.4

可以通过编辑 zipfile.py 源代码中的第 205 行来修复它:

Was able to fix it by editing line 205 in zipfile.py source code:

if diskno != 0 or disks != 1:
    raise BadZipFile("zipfiles that span multiple disks are not supported")

到:

if diskno != 0 or disks > 1:
