Hi !

I would like to add a RESTful interface to an existing Twisted application. To allow a human to interact easily with the application, I want to output bare minimal XHTML (1990 HTML without any presentation, just some class to allow to easily parse the result).

I have looked at twisted.web framework. One good point is that there are different methods for each action (GET, HEAD, POST, PUT, DELETE). However, there is nothing to generate XHTML easily.

I have looked at Nevow which contains two interesting ways to generate XHTML code (Stan and templates). But the only method to render is renderHTTP. I suppose that the HTTP action is somewhere in the context, but I did not find where yet.

To obtain the request, do this: request = inevow.IRequest(ctx) Then, just dispatch based on request.method

I could mix twisted.web with Stan or with Nevow templates. I could also just use twisted.web and use ElementTree to generate simple XHTML page. But do some of you have some suggestions about implementing a RESTful service using Twisted ?

It really depends upon your personal tastes in this case. You could use plain twisted.web, with some templating library; you could use twisted.web2 with some templating library; you could use nevow. All will work just fine in a REST-style design, as they all support the same basic IResource interface, more or less. Hope this helps, Daniel
