I’m playing with wsgiref.simple_server
to study the world of web servers.
I would like to control the log generated, but could not find anything about it in Python’s documentation.
My code looks like this:
from wsgiref.simple_server import make_server def application(environ, start_response): start_response('200 OK', headers) return ['Hello World'] httpd = make_server('', 8000, application) httpd.serve_forever()

wsgiref.simple_server.make_server
by default creates a WSGIServer
with WSGIRequestHandler
:
def make_server( host, port, app, server_class=WSGIServer, handler_class=WSGIRequestHandler): """Create a new WSGI server listening on `host` and `port` for `app`""" server = server_class((host, port), handler_class) server.set_app(app) return server
WSGIRequestHandler
here extends from BaseHTTPServer.BaseHTTPRequestHandler
, where the logging magic turns out to be:
def log_message(self, format, *args): sys.stderr.write("%s - - [%s] %sn" % (self.client_address[0], self.log_date_time_string(), format%args))
So it’s logging to stderr, actually, not to python logging module. You can override this in your own handler:
class NoLoggingWSGIRequestHandler(WSGIRequestHandler): def log_message(self, format, *args): pass
And pass your custom handler to the server instead:
httpd = make_server('', 8000, application, handler_class=NoLoggingWSGIRequestHandler)
