How do I use the wrap-multipart-params to proccess "upload file"

[nesteiner]

when i try to use wrap-multipart-params,what i want is to upload file from form,and i need to save upload file into a designation directory. however there is no more information in the API DOC,there isn't any example for the :store option http://ring-clojure.github.io/ring/ring.middleware.multipart-params.html#var-wrap-multipart-params

Does the wiki page on file uploads answer your question?

I'sure it's has solved my question a lot,but here is something left. is that means i just need to operate the :temp-file---move it?? what about that when i want to store the tempfile in a desigational directory by default

by the way,this page can not be founded,which is titled as example for FIle Upload https://gist.github.com/thescalaguy/c743bf7c93f6363f3d22de28c7c9bb3d

Yes. Typically you'll validate the file in some way, then move the temporary file to wherever you want as part of your handler's logic.

You could write your own custom store, but it's easier just to move the temporary file.
