我正在尝试保存使用 clj-http 下载的文件
我有以下代码:
(def test-file
(cl/get "http://placehold.it/350x150"))
(defn write-file []
(with-open [w (clojure.java.io/writer "test-file.gif" :append true)]
(.write w (:body test-file))))
当我尝试将其制作为字节数组时,我得到了一个异常:
user=> (def test-file
(cl/get "http://placehold.it/350x150" {:as :byte-array}))
#'user/test-file
user=> (write-file)
IllegalArgumentException No matching method found: write for class java.io.BufferedWriter clojure.lang.Reflector.invokeMatchingMethod (Reflector.java:79)
帮助!
使用二进制输出。
(def test-file
(client/get "http://placehold.it/350x150" {:as :byte-array}))
(defn write-file []
(with-open [w (java.io.BufferedOutputStream. (java.io.FileOutputStream. "test-file.gif"))]
(.write w (:body test-file))))
编辑:输出流更好:
(defn write-file []
(with-open [w (clojure.java.io/output-stream "test-file.gif")]
(.write w (:body test-file))))
更新:
优雅的方式:
(clojure.java.io/copy
(:body (client/get "http://placehold.it/350x150" {:as :stream}))
(java.io.File. "test-file.gif"))
