Question

Clojure's transit不支持开箱即用的Joda时间格式。如何为org.joda.time.DateTime添加写支持？

Answer 1

添加此功能：

(def joda-time-writer
  (transit/write-handler
   (constantly "m")
   #(-> % coerce/to-date .getTime)
   #(-> % coerce/to-date .getTime .toString)))

并像这样使用它：

(transit/writer out :json
                    {:handlers {org.joda.time.DateTime joda-time-writer}})

Answer 2

要使用ring-middleware-format工作，请使用David J发布的joda-time-writer函数执行此操作。

(defn wrap-format [handler]
  (let [transit-opts {:handlers {org.joda.time.DateTime
                                 joda-time-writer}}]
    (wrap-restful-format handler
                         {:response-options
                          {:transit-json transit-opts
                           :transit-messagepack transit-opts}})))
