[Developers] metaweb.py- when readservice returns a gzip'd response

[Bob Skinner]

Hi,

I'm just getting started with the python interface using the metaweb.py example from Appendix B. (Using python 2.4)

Using the .login or .read methods right "out of the box" always returned a 
"ValueError: No JSON object could be decoded" error in the simplejson.load call.

The reason was the response was gzip encoded, I had to change the read method from:

    f = urllib2.urlopen(req)        # Open the URL
    response = simplejson.load(f)

to:

    f = urllib2.urlopen(req)        # Open the URL
    if 'Content-Encoding' in f.info() and f.info()['Content-Encoding'] == 'gzip':
        buf = cStringIO.StringIO(f.read())
        gbuf = gzip.GzipFile(mode='rb', fileobj=buf)
        response = simplejson.load(gbuf)   # Parse JSON response to an object
    else:
        response = simplejson.load(f)


I couldn't find anything on the documentation or in the developer mailing list archives to this end.    Is there some better way of handling this that I should be using?

best regards,
Bob Skinner

p.s.   I think you guys are on to something HUGE with Freebase.  Your implementation/api looks stellar.  I'm a big fan.
