Large file cause MemoryError

[JokerQyou]

Hi there, it's me again.
Since the last time I asked about download large file streamly via OAuth2 , I eventually found there's possibly a bug in your code. I noticed an unnormal RAM usage which would even use up all RAM on old computers. This happens during the last few seconds of downloading a file (50+ MB).

And I found this is somethins related to this line:

py-oauth2/pyoauth2/libs/response.py

Line 29 in 313f195

self.body = response.text

If changed to:

        options = {'parse': 'text'}
        options.update(opts)
        if options['parse'] in ('text', 'query', 'json', ):
            self.body = response.text

would solve this problem, and also lower the RAM usage during small size file downloading.

            self.body = response.text
