Would you have WSGI middleware examples?

Hello,
Circuits is greate work!
But documents are scattered and I can't fine a middleware example.
Would you have examples?

[James Mills]

Hello,

Do you mean circuits.web - the web framework?

Please define more specifically what you mean by "middle-ware".

The reason I say this is because of the way circuits.web is

designed (on top of the circuits asynchronous framework)

circuits.web makes no distinction between WSGI Applications,

Middle-ware or Gateways. They are all just "components" that

behave differently and unfortunately there was no clear concept

that could be brought over to circuits.web from WSGI that made

sense for defining "middle-ware behavior".

For example, in my view WSGI Middle-ware means

modifying some part of the request/response as it

is processes through a WSGI Application/Gateway

in some way.

circuits.web achieves this very well by use of the

circuits architecture (components and event handlers)

by allowing you to defining components that allow you

to intercept the request/response and modify it on it's

way through from User to Server and back to User.

I hope this makes sense and if you have further questions

please don't hesitate to ask or come speak to me on

IRC :)

cheers

James

Hi, James

Oh “WSGI” is missing. I'm sorry. “middleware” I said, it was meant to
be a WSGI middleware. I had not be discreet.

Thank you for your detailed explanation. I can understand that I have
to intercept request and response in component. But I'm still
wondering how to handle ingress and egress in WSGI middleware stack.
This month, I wrote a authentication and authorisation package using
repoze.who, repoze.what and PyMongo. I'd be happy to apply the things
within circuits.web. I'll try.

Thank you

cheers

Hi,

There are a couple of "middle-ware" (ish) examples in

circuits.web under the examples directory. Should come

packaged with circuits - or it's in the source tree.

There's also a few authentication examples as well

including shadow auth.

cheers
