使用ZipFile从Python的zip文件中提取.app [英] Extracting a .app from a zip file in Python, using ZipFile

问题描述

我正在尝试从快照中提取Chromium.app的新修订版，并且可以很好地下载文件，但是在提取文件时，ZipFile要么将其中的chrome-mac文件夹提取为文件，目录不存在，等等.我对python还是很陌生，所以这些错误对我来说意义不大.这是我到目前为止所拥有的.

I'm trying to extract new revisions of Chromium.app from their snapshots, and I can download the file fine, but when it comes to extracting it, ZipFile either extracts the chrome-mac folder within as a file, says that directories don't exist, etc. I am very new to python, so these errors make little sense to me. Here is what I have so far.

import urllib2
response = urllib2.urlopen('http://build.chromium.org/buildbot/snapshots/chromium-rel-mac/LATEST')
latestRev = response.read()
print latestRev

# we have the revision, now we need to download the zip and extract it
latestZip = urllib2.urlopen('http://build.chromium.org/buildbot/snapshots/chromium-rel-mac/%i/chrome-mac.zip' % (int(latestRev)), '~/Desktop/ChromiumUpdate/%i-update' % (int(latestRev)))
#declare some vars that hold paths n shit
workingDir = '/Users/slehan/Desktop/ChromiumUpdate/'
chromiumZipPath = '%s%i-update.zip' % (workingDir, (int(latestRev)))
chromiumAppPath = 'chrome-mac/' #the path of the chromium executable within the zip file
chromiumAppExtracted = '%s/Chromium.app' % (workingDir) # path of the extracted executable

output = open(chromiumZipPath, 'w') #delete any current file there
output.write(latestZip.read())
output.close()

# we have the .zip now we need to extract the Chromium.app file, it's in ziproot/chrome-mac/Chromium.app
import zipfile, os
zippedFile = open(chromiumZipPath)
zippedChromium = zipfile.ZipFile(zippedFile, 'r')
zippedChromium.extract(chromiumAppPath, workingDir)
#print zippedChromium.namelist()

zippedChromium.close()
#zippedChromium.close()

有什么想法吗?

推荐答案

似乎您在Python中遇到了 bug .此其他问题详细说明了问题和解决方法.您可以选择使用其中一种解决方法，也可以更新到Python 2.6.5或2.7b2.

It seems you have encountered a bug in Python. This other question details the problem and workarounds. You can elect to use one of those workarounds, or update to Python 2.6.5 or 2.7b2.

解决方法之一建议复制修补的zip文件固定的Python中的.py模块.

One of the workarounds suggests copying the patched zipfile.py module from the fixed Python.
