that puzzles me also.
fortunately, in the appengine ENV the Accept-Encoding was handled
transparently.
but in the development app box. the accept-encoding disabled, that's
not advantageous when developing.
as the temporary solution,i added a replace interface,that support the
accept-encodeing header, in myself lib when develop instead of
urlfetch :
looks like:
import sys,os
if (os.environ['SERVER_SOFTWARE']).find('Development') == -1: #in
the appengine box
from google.appengine.api import urlfetch
else: # in the develop appserver
from common import urlfetch
in urlfetch.py:
class Respon(object):
content = None
status_code = ""
headers = {}
def fetch(url,headers ={'Accept-Encoding':'gzip'}):
import urllib2, httplib
import os,sys
import StringIO
sys.path.insert(0,os.environ['PROJECT_ROOT'])
request = urllib2.Request('')
respon = Respon()
request = urllib2.Request(url)
for k,v in headers.iteritems():
request.add_header( k , v)
opener = urllib2.build_opener()
f = opener.open(request)
data= f.read()
if (f.headers.get('Content-Encoding','')).find('zip') == 1 :
#zipped
import gzip,StringIO
compressedstream = StringIO.StringIO(data)
gzipper = gzip.GzipFile(fileobj=compressedstream)
data = gzipper.read()
respon.content = data
respon.status_code = str(f.code)
respon.headers = dict(f.headers)
return respon
