Clojure: convert a map with keyword keys to one with equivalent string keys

Question

I have a map like {:a "A" :b "B"} and want to convert its keys to strings, e.g. {"a" "A" "b" "B"}.

I have this function, which works:

(defn keyword-keys->strs [m]
  (zipmap
    (map name (keys m))
    (map second (vec m))))

But is there a more idiomatic or purpose-built way to do it?

Thanks!

有一个内置函数可以将映射键递归转换为字符串：

(clojure.walk/stringify-keys {:a "A" :b "B"})
=> {"a" "A", "b" "B"}
(clojure.walk/stringify-keys {:a "A" :b {:c "C"}})
=> {"a" "A", "b" {"c" "C"}}
