我的代码有问题。我试图让一个脚本工作,可以使一个ePub文件。它们是压缩的zip文件,压缩后(即不压缩)必须按顺序执行。当前脚本将创建一个.zip,但它不可用a在运行zip -t
命令时在Python Shell和终端应用程序中创建错误。
有关的错误在Python shell上如下:
Traceback (most recent call last):
File "/Users/Hal/Documents/GitHub/Damore-essay-ebook/GenEpub-old.py", line 29, in <module>
if zipfile.is_zipfile(zf) is True:
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/zipfile.py", line 183, in is_zipfile
result = _check_zipfile(fp=filename)
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/zipfile.py", line 169, in _check_zipfile
if _EndRecData(fp):

fpin.seek(0, 2)
AttributeError: 'ZipFile' object has no attribute 'seek'
Mac终端上有问题的错误(尽管我确信无论我在哪里运行zip -t
:
Archive: IdealogicalEcho.epub
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of IdealogicalEcho.epub or
IdealogicalEcho.epub.zip, and cannot find IdealogicalEcho.epub.ZIP, period.
Python源代码:
#!/usr/bin/env python
#GenEpub.py - Generates an .epub file from the data provided.
#Ideally with no errors or warnings from epubcheck (needs to be implemented, maybe with the Python wrapper).
import os
import json
import zipfile
with open('metadata.json') as json_file:
data = json.load(json_file)
#The ePub standard requires deflated compression and a compression order.
zf = zipfile.ZipFile(data["fileName"] + '.epub', mode='w', compression=zipfile.ZIP_STORED)
zf.write(data["fileName"] + '/mimetype')
for dirname, subdirs, files in os.walk(data["fileName"] + '/META-INF'):
zf.write(dirname)
for filename in files:
zf.write(os.path.join(dirname, filename))
for dirname, subdirs, files in os.walk(data["fileName"] + '/EBOOK'):
zf.write(dirname)
for filename in files:
zf.write(os.path.join(dirname, filename))
#zipfile has a built-in validator for debugging
if zipfile.is_zipfile(zf) is True:
print("ZIP file is valid.")
#Extra debugging information

#print(getinfo.compress_size(zf))
#print(getinfo.file_size(zf))
zf.close()
