Using uWSGI on Python 3.x

The WSGI standard has been updated to support python3.x string handling.

The new PEP is the 3333

This is an example of a valid WSGI app for python3.x

def application(environ, start_response):
	start_response('200 OK', [('Content-Type', 'text/plain')])
	return b'Hello World'

So, all must be unicode "str" object limited to latin1 character set, except for the response body that must be a sequence of zero or more bytes.

uWSGI notes

To support multiple applications via the uwsgi.applications dict you must set the dictionary key as bytes:

import uwsgi

def app1(e, sr):
        print(e)
        sr('200 Ok', [('Content-Type','text/plain')])
        return b'i Am a Python 3.x bytestring'

def app2(e, sr):
        print(e)
        sr('404 Not Found', [('Content-Type','text/plain')])
        return b'i Am a Python 3.x Not Found page'


uwsgi.applications = {b'': app1, b'/test': app2}
