将urllib2提取的压缩数据转换为HTML [英] Convert gzipped data fetched by urllib2 to HTML

问题描述

我目前使用机械化方法来读取压缩后的网页，如下所示:

I currently use mechanize to read gzipped web page as below:

br = mechanize.Browser()
br.set_handle_gzip(True)
response = br.open(url)
data = response.read()

我想知道如何将urllib2提取的压缩数据解压缩为HTML文本吗?

I wonder how to decompress gzipped data fetched by urllib2 to HTML text?

req = urllib2.Request(url)
opener = urllib2.build_opener()
response = opener.open(req)
data = response.read()
if response.info()['content-encoding'] == 'gzip':
    HOW TO DECOMPRESS DATA TO HTML

推荐答案

尝试一下:

import StringIO
data = StringIO.StringIO(data)
import gzip
gzipper = gzip.GzipFile(fileobj=data)
html = gzipper.read()

html现在应该包含HTML(打印以查看).有关更多信息，请参见此处.

html should now hold the HTML (Print it to see). See here for more info.
