Werkzeug is a WSGI utility library for Python. It's widely used and BSD licensed.
from werkzeug.wrappers import Request, Response
@Request.application
def application(request):
return Response('Hello World!')
if __name__ == '__main__':
from werkzeug.serving import run_simple
run_simple('localhost', 4000, application)
Werkzeug started as a simple collection of various utilities for WSGI applications and has become one of the most advanced WSGI utility modules. It includes a powerful debugger, fully featured request and response objects, HTTP utilities to handle entity tags, cache control headers, HTTP dates, cookie handling, file uploads, a powerful URL routing system and a bunch of community contributed addon modules.
It does Unicode and doesn't enforce a specific template engine, database adapter or anything else. It doesn't even enforce a specific way of handling requests and leaves all that up to the developer.
- HTTP header parsing and dumping
- Easy to use request and response objects
- Interactive JavaScript based in-browser debugger
- 100% WSGI 1.0 compatible
- Supports Python 2.6, 2.7 and 3.3+
- Unicode support
- Basic session and signed cookie support
- URI and IRI utilities with unicode awareness
- builtin library of fixes for buggy WSGI servers and browsers
- integrated routing system for matching URLs to endpoints and vice versa
Werkzeug is the base of frameworks such as Flask and more, as well as in house frameworks developed for commercial products and websites.
Have you looked at werkzeug.routing? It's hard to find anything that's simpler, more self-contained, or purer-WSGI than Werkzeug, in general — I'm quite a fan of it! — Alex Martelli
