Title: Using xmlrpc-client.lsp...

Hi!

I ran into a little problem when using %xmlrpc-client.lsp with our python/django XMLRPC server at work. It has a very strict interpretation of how many arguments it will accept for certain functions, like system.listMethods, so the default request with the single dummy argument won't work.

I wound up adding something like this to xmlrpc-client.lsp:

Code Select Expand

(define (format-request method)
  "( method /arg.../ -- XML) Compose XML request."

  (let ((xml (format
	      "<?xml version="1.0"?><methodCall><methodName>%s</methodName><params>"
	      method)))
    (dolist (value (args))
      (push (format "<param><value>%s</value></param>" value) xml -1))
    (push "</params></methodCall>n" xml -1)))

Then changing system.listMethods to:

Code Select Expand

(define (system.listMethods url)
    (execute url (format-request "system.listMethods")))

Technically, format-request should also determine the type of the argument values (and encode lists and dictionaries correctly), but if you're only using string arguments, it should suffice.

Maybe someone has a better format-request they could share? ; - )
