How do you download an image from the web and save it to your file system using Clojure? I know the image url and I\'m aware that I can\'t use spit and sl

Zhitong He pointed me to this solution, which worked best for my purposes:

 (defn copy [uri file]
  (with-open [in (io/input-stream uri)
              out (io/output-stream file)]
    (io/copy in out)))

As Zhitong notes, you'll need (:require [clojure.java.io :as io]) in your namespace to use this as coded. Alternatively, you could refer to clojure.java.io directly:

(defn copy-uri-to-file [uri file]
  (with-open [in (clojure.java.io/input-stream uri)
              out (clojure.java.io/output-stream file)]
    (clojure.java.io/copy in out)))
