I'm not sure how that would be handled with noir.
With plain ring, you would use the multipart-params middleware [1] to get a
:multipart-params submap in the request, in which all uploaded files are
passed.
At this point you can process them with
(doseq [[param-name {:keys [filename content-type bytes]}]
(:multipart-params request)]
...) ;; if you used multipart-params.byte-array, or
(doseq [[param-name {:keys [filename content-type tempfile size]}]
(:multipart-params request)]
...) ;; if you used multipart-params.temp-file
