Use (web uri).  Specifically string->uri and uri-query.

Once you have the query string, you can pick apart the pieces with
something like this:

  (define* (parse-www-form-urlencoded str #:optional (charset "utf-8"))
    (map
     (lambda (piece)
       (let ((equals (string-index piece #\=)))
         (if equals
             (cons (uri-decode (substring piece 0 equals) #:encoding charset)
                   (uri-decode (substring piece (1+ equals)) #:encoding 
charset))
             (cons (uri-decode piece #:encoding charset) ""))))
     (string-split str #\&)))
