[Lispweb] POST variables in araneida

[Richard Newman]

James,
   You might be interested in something like

   (flet
     ((write-body-bindings (binding-specifiers body)
        "Auxiliary function for with-request-params."
        (loop for (var param &optional type-fun) in binding-specifiers
              collecting
              (list var
                    (if type-fun
                      (list type-fun (list 'body-param param body))
                      (list 'body-param param body))))))

     (defmacro with-body-params (request binding-specifiers &body body)
       "Each binding specifier is a triple, (var param &optional type- 
fun).
        If TYPE-FUN is not provided, CAR is used to get rid of the  
wrapping
        list that URL-QUERY-PARAM returns."
       (let ((r-body (gensym)))
         `(let ((,r-body (request-body ,request)))
            (let (,@(write-body-bindings binding-specifiers r-body))
              , at body)))))

   which will save you typing out a load of calls to BODY-PARAM, if  
you're using form-encoded bodies.

   I'm sure Alan has something a lot more integrated!

   Take a look in (IIRC) daemon.lisp to see how bodies are handled.  
We had some discussion of this many moons ago.
