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))))
当我尝试使其成为一个字节数组时,我得到一个例外：
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)
帮帮我！
解决方法
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：
输出流越好：
(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"))
