Convert gzipped data fetched by urllib2 to HTML

Question

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()         


        

Answer 1

Try this:

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

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

Answer 2

def ungzip(r,b):
    headers = r.info()
    if ('Content-Encoding' in headers.keys() and headers['Content-Encoding']=='gzip') or \
       ('content-encoding' in headers.keys() and headers['content-encoding']=='gzip'):
        import gzip
        gz = gzip.GzipFile(fileobj=r, mode='rb')
        html = gz.read()
        gz.close()
        headers['Content-type'] = 'text/html; charset=utf-8'
        r.set_data(html)
        b.set_response(r)
