Question

我有一个json响应，并希望得到这些值：

(cheshire.core/parse-string (:body picList))

{"photoset" {"primary" "8455893107", "total" "1", "pages" 1, "perpage" 500, "page" 1,
"per_page" 500, "photo" [{"id" "8455893107", "secret" "1a3236df06", "server" "8087", 
"farm" 9, "title" "IMG_0137", "isprimary" "1"}], "owner" "93029076@N07", "id" 
"72157632724688181", "ownername" "clojureB5"}, "stat" "ok"}

如何获得不同的值，例如photoset-＆gt; primary或photoset-＆gt; photo-＆gt; id？我尝试使用(map #(get % "photoset")...，但它确实有效。

谢谢！

我认为你正在寻找clojure.core/get-in

(get-in your-parsed-json ["photoset" "primary"]) ;; "8455893107"

(-> (get-in your-parsed-json ["photoset" "photo"])
  first
  (get "id")) ;; "8455893107"

(get-in your-parsed-json ["photoset" "photo" 0 "id"]) ;; "8455893107"

clojure从json响应中获取数据
