WSGI go is a very simple WSGI router with no requirements. It is written for Python 3, though it could be easily backported.
pip install wsgigo
You can use it to route WSGI requests to specific apps based on hostname, URL fragment, or (through extending the Route class) other criteria. For example, suppose you have three wsgi apps which you want to serve as one::
from wsgigo import AppRouter
app = AppRouter(default_app=main_website)
app.add_startswith(docs_app, '/docs/')
app.add_hostname(api_app, 'api.local')
app.add_regexp(animal_app, '/(?:monkey|ape)/')You can also make your own router class, to route apps how you need them to be routed::
class InternetExplorerRouter(Route):
def claim(self, environ):
user_agent = environ['HTTP_USER_AGENT']
if 'Trident/7.0' in user_agent or 'MSIE' in user_agent:
return True
internet_explorer_app = TestWsgiApp("<b>really simple webpage</b>")
real_app = TestWsgiApp("<b>really ADVANCED webpage</b>")
router = AppRouter(default_app=real_app)
router.add_route(InternetExplorerRouter(internet_explorer_app))
