我想使用urllib下载文件并在保存之前将文件解压缩到内存中.

这就是我现在所拥有的:

response = urllib2.urlopen(baseURL + filename)
compressedFile = StringIO.StringIO()
compressedFile.write(response.read())
decompressedFile = gzip.GzipFile(fileobj=compressedFile, mode='rb')
outfile = open(outFilePath, 'w')
outfile.write(decompressedFile.read())

这最终会写出空文件.我怎样才能实现我追求的目标？

更新答案:

#! /usr/bin/env python2
import urllib2
import StringIO
import gzip

baseURL = "https://www.kernel.org/pub/linux/docs/man-pages/"        
# check filename: it may change over time, due to new updates
filename = "man-pages-5.00.tar.gz" 
outFilePath = filename[:-3]

response = urllib2.urlopen(baseURL + filename)
compressedFile = StringIO.StringIO(response.read())
decompressedFile = gzip.GzipFile(fileobj=compressedFile)

with open(outFilePath, 'w') as outfile:
    outfile.write(decompressedFile.read())
