Bug description:
  In PY3, dict.keys() will return a view of list but not a list anymore, i.e.
  $ python3.4
  Python 3.4.3 (default, Mar 31 2016, 20:42:37) 
  >>> body={"11":"22"}
  >>> body[body.keys()[0]]
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  TypeError: 'dict_keys' object does not support indexing

  so for py3 compatible we should change it as follows:
  >>> body[list(body.keys())[0]]
  '22'
