从zip文件中提取文件并保留修改日期? [英] Extract files from zip file and retain mod date?

问题描述

我正在尝试使用Python 2.7.1(在Windows上，fyi)从zip文件中提取文件，并且每次尝试都显示具有Modified Date =提取时间的提取文件(不正确).

I'm trying to extract files from a zip file using Python 2.7.1 (on Windows, fyi) and each of my attempts shows extracted files with Modified Date = time of extraction (which is incorrect).

import os,zipfile
outDirectory = 'C:\\_TEMP\\'
inFile = 'test.zip'
fh = open(os.path.join(outDirectory,inFile),'rb') 
z = zipfile.ZipFile(fh)
for name in z.namelist():
    z.extract(name,outDirectory)
fh.close()

我也尝试使用.extractall方法，结果相同.

I also tried using the .extractall method, with the same results.

import os,zipfile
outDirectory = 'C:\\_TEMP\\'
inFile = 'test.zip'
zFile = zipfile.ZipFile(os.path.join(outDirectory,inFile))        
zFile.extractall(outDirectory)

有人可以告诉我我在做什么错吗?

Can anyone tell me what I'm doing wrong?

我想这是可能的，而不必每个

I'd like to think this is possible without having to post-correct the modified time per How do I change the file creation date of a Windows file?.

推荐答案

嗯，确实需要一些后期处理，但是还不错:

Well, it does take a little post-processing, but it's not that bad:

import os
import zipfile
import time

outDirectory = 'C:\\TEMP\\'
inFile = 'test.zip'
fh = open(os.path.join(outDirectory,inFile),'rb') 
z = zipfile.ZipFile(fh)

for f in z.infolist():
    name, date_time = f.filename, f.date_time
    name = os.path.join(outDirectory, name)
    with open(name, 'wb') as outFile:
        outFile.write(z.open(f).read())
    date_time = time.mktime(date_time + (0, 0, -1))
    os.utime(name, (date_time, date_time))

好的，也许是那么糟糕.
