Request Logging for WSGI Web Applications
This is a middleware which you can use to log requests to your WSGI based site. It's even imitating Apache's combined log format to allow you to use any of the many tools for Apache log file analysis.
By making use of Python's standard library logging facilities, you can easily set it up to log to STDOUT, time rotated log files, email, syslog, etc.
Simply install this Python module via
pip install wsgi-request-logger
To add this middleware to your WSGI
application and log to the file access.log, do:
from requestlogger import WSGILogger, ApacheFormatter from logging.handlers import TimedRotatingFileHandler def application(environ, start_response): response_body = 'The request method was %s' % environ['REQUEST_METHOD'] response_body = response_body.encode('utf-8') response_headers = [('Content-Type', 'text/plain'), ('Content-Length', str(len(response_body)))] start_response('200 OK', response_headers) return [response_body] handlers = [ TimedRotatingFileHandler('access.log', 'd', 7) , ] loggingapp = WSGILogger(application, handlers, ApacheFormatter()) if __name__ == '__main__': from wsgiref.simple_server import make_server http = make_server('', 8080, loggingapp) http.serve_forever()
This WSGI middleware was originally developed under the name wsgilog by L. C. Rees. It was forked by Philipp Klaus in 2013 to build a WSGI middleware for request logging rather than exception handling and logging.
