スナップショットから Chromium.app の新しいリビジョンを抽出しようとしていますが、ファイルを正常にダウンロードできますが、抽出に関しては、ZipFile は内部の chrome-mac フォルダーをファイルとして抽出し、ディレクトリはそうではないと言います ' t が存在するなど。私は python を初めて使用するので、これらのエラーはほとんど意味がありません。これが私がこれまでに持っているものです。

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()

何か案は？

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.

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

Best of luck!

これは別のカットです。これは同じテクニックですが、結果を見て、それが機能することを示しています。

import os
import urllib2
import zipfile
from StringIO import StringIO

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

# we have the revision, now we need to download the zip and extract it
locRef='http://build.chromium.org/buildbot/snapshots/chromium-rel-mac/%i/chrome-mac.zip' % (int(latestRev))
latestZip = StringIO(urllib2.urlopen(locRef).read())

# we have the .zip now we need to extract the Chromium.app file, it's in chrome-mac/Chromium.app/
zippedChromium = zipfile.ZipFile(latestZip)
# find all zip members in chrome-mac/Chromium.app
members = [m for m in zippedChromium.namelist() if m.startswith('chrome-mac/Chromium.app/')]
#zippedChromium.extract(chromiumAppPath, workingDir)
target = 'chromium-%s' % latestRev
if os.path.isdir(target):
    print 'destination already exists, exiting'
    raise SystemExit(1)
os.makedirs(target)
zippedChromium.extractall(target, members)

lengths = [
    (len(dirnames), len(filenames))
    for dirpath, dirnames, filenames in os.walk(target)
    ]
dirlengths, filelengths = zip(*lengths)
ndirs = sum(dirlengths)
nfiles = sum(filelengths)
print 'extracted %(nfiles)d files in %(ndirs)d dirs' % vars()
#zippedChromium.close()

実行したときに得られる出力は

> .\getapp.py
getting revision 48479
extracted 537 files in 184 dirs

これは私のために働いているようです：

import os
import urllib2
import zipfile
from StringIO import StringIO

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

# we have the revision, now we need to download the zip and extract it
locRef='http://build.chromium.org/buildbot/snapshots/chromium-rel-mac/%i/chrome-mac.zip' % (int(latestRev))
latestZip = StringIO(urllib2.urlopen(locRef).read())

# we have the .zip now we need to extract the Chromium.app file, it's in chrome-mac/Chromium.app/
zippedChromium = zipfile.ZipFile(latestZip)
# find all zip members in chrome-mac/Chromium.app
members = [m for m in zippedChromium.namelist() if m.startswith('chrome-mac/Chromium.app/')]
#zippedChromium.extract(chromiumAppPath, workingDir)
target = 'chromium-%s' % latestRev
if os.path.isdir(target):
    print 'destination already exists, exiting'
    raise SystemExit(1)
os.makedirs(target)
zippedChromium.extractall(target, members)

#zippedChromium.close()
