[araneida-devel] request-authorized-p (implementation of generic function to yield authorization status)
by Joubert Nel 05 Mar '07

05 Mar '07

Hi, I'm trying to create an authorization scheme in Araneida. Basically whenever a location in my URL space is called I want to check whether the user is authorized and redirect to a login page if he isn't. I found this post on usenet: http://groups.google.com/group/comp.lang.lisp/browse_thread/thread/a6990567… According to this post, the generic function "request-authorized-p" is called for every request to determine whether a client is authorized. To test this, I've got: ============= snip ================== (defclass root-page-handler (araneida:handler) ()) (defmethod request-authorized-p ((araneida:handler root-page-handler) method request) (format t "not authorized")) (defmethod request-not-authorized ((araneida:handler root-page-handler) method request) (araneida:request-redirect request *login-urlstring*)) (defmethod handle-request-response ((araneida:handler root-page-handler) method request) (araneida:request-send-headers request) (araneida:html-stream (araneida:request-stream request) `(html (body (p "logged in"))))) (defparameter *root-page-handler-instance* (make-instance 'root-page-handler)) (araneida:install-handler (http-listener-handler *listener*) *root-page-handler-instance* *app-urlstring* t) ============= snip ================== So, I've got request-authorized-p on class root-page-handler. However, I find that this method is never called by Araneida; instead, handle-request-response is still called. What gives? What am I missing? Joubert

[araneida-devel] utf-8 and unsigned-byte 8
by Johan Ur Riise 05 Mar '07

I have a patch that enables utf-8 request streams, and at the same time let me send binary files using the static file handler. The idea is to open a (unsigned-byte 8) stream in the accept, then immediately replace it with a flexi-stream of type character with external encoding utf-8. After that, the stream can be reconfigured to unsigned-byte, for instance for sending the content in a file download. A problem is that it introduces ainother dependancy, to the flexi-streams package by E Weitz. Anyway, it's attached -- Hilsen Johan Ur Riise
