Here is what I have tried. I don't see how to get the protocol with str(). 
Would you please show me the example code? Thanks.

$ cat ./main.py 
#!/usr/bin/env python
# vim: set noexpandtab tabstop=2 shiftwidth=2 softtabstop=-1 
fileencoding=utf-8:

from webob import Request, Response

def my_app(environ, start_response):
    req = Request(environ)
    res = Response()
    res.content_type = 'text/plain'
    parts = []
    for name, value in sorted(req.environ.items()):
        parts.append('%s: %r' % (name, value))
    res.body = '\n'.join(parts)
    return res(environ, start_response)
req = Request.blank('/')
res = req.get_response(my_app)
print res
$  ./main.py 
200 OK
