JSON string decoding error

I am calling the URL :

http://code.google.com/feeds/issues/p/chromium/issues/full/291?alt=json

using urllib2 and decoding using the json module

url = "http://code.google.com/feeds/issues/p/chromium/issues/full/291?alt=json"
request = urllib2.Request(query)
response = urllib2.urlopen(request)
issue_report = json.loads(response.read())

I run into the following error :

ValueError: Invalid control character at: line 1 column 1120 (char 1120)

I tried checking the header and I got the following :

Content-Type: application/json; charset=UTF-8

I also tried adding an encoding parameter as follows :

issue_report = json.loads(response.read() , encoding = 'UTF-8')

I still run into the same error.

The feed has raw data from a JPEG in it at that point; the JSON is malformed, so it's not your fault. Report a bug to Google.

You could consider using lxml instead, since the JSON is malformed. It's XPath support makes working with XML pretty straight-forward:

import lxml.etree
url = 'http://code.google.com/feeds/issues/p/chromium/issues/full/291'
doc = lxml.etree.parse(url)
ns = {'issues': 'http://schemas.google.com/projecthosting/issues/2009'}
issues = doc.xpath('//issues:*', namespaces=ns)

Fairly easy to manipulate elements, for instance to strip namespace from tags, convert to dict:

>>> dict((x.tag[len(ns['issues'])+2:], x.text) for x in issues)
<<<
