我无法使用compojure-api来正确验证具有Inst模式的查询参数的错误数据

标签: clojure compojure compojure-api

在这里,我使用<!-- Button trigger modal --> <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal"> Launch demo modal </button> <!-- Modal --> <div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Modal title</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body"> ... </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> <button type="button" class="btn btn-primary">Save changes</button> </div> </div> </div> </div> 库为我的api配置了metosin/compojure-api端点。您将看到我还使用GET /fetch来验证此端点上的查询参数输入,并plumatic/schema来验证任何不良数据异常。

siilisolutions/humanize

当我发出以下请求时,端点返回200 ok。

(defn humanize-schema-exception [^Exception e]
  (if (instance? schema.utils.ErrorContainer (ex-data e))
    (#'humanize/explain (:error (ex-data e))
      (fn [x]
        (let [Inst java.util.Date]
          (clojure.core.match/match
            x
            ['not ['instance? Inst not-inst]]
            (str "'" not-inst "' is not a timestamp.")
            :else x))))))

(defn bad-request-handler
  "Handles bad requests."
  [f]

  (fn [^Exception e data request]
    (let [message (humanize-schema-exception e)]

      (f message))))

(def app
    (api
        {:exceptions {:handlers
                      {::ex/request-parsing    (parse-exception-handler response/bad-request)
                       ::ex/request-validation (bad-request-handler response/bad-request)
                       ::ex/default            (exception-handler response/internal-server-error)}}
         :swagger    {:ui   "/api/v1.0/docs"
                      :spec "/api/v1.0/swagger.json"}

         (GET "/fetch" []
           :query-params [{id :- schema/Int nil}
                          {timestamp_from :-  schema/Inst nil}
                          {timestamp_to :- schema/Inst nil}]
           :responses {200 {:description "ok"}
                       400 {:description "bad request"}} (foo id timestamp_from timestamo_to))))

但是当使用错误数据设置timestamp_from时,如下所示:

curl -X GET --header 'Accept: application/json' 'http://localhost:3000/fetch?timestamp_from=2018-01-01T10%3A00%3A00'

我得到以下异常:

curl -X GET --header 'Accept: text/html' 'http://localhost:3000/api/v1.0/task?timestamp_from=blah%20blah%20blah'

我希望还能看到更像这样的东西:

这是ring-swagger中的一个功能/错误,它正在进行字符串 - &gt;日期转换。它应该捕获解析异常并发出更好的错误,但不会。
