Question

我正在使用AngularJS资源基本上是$ .ajax（）一些表单数据。

Post.put({user:$scope.getLoggedInUser(), action:"new"},{body:$scope.postBody, "public":$scope.postPublic}, function(post) {

表单上有一个名为“public”的复选框。

我正在使用此函数将表单数据与URL中的参数合并：

(defn get-params [request]
  (merge (:params request) (parse-string (slurp (request :body)) true)))

当我从路线的处理程序中打印出来时，如果选中该复选框，我会得到一个很好的true：

(println (:public (get-params request)))

然而，当我将参数（即不是println）传递给我的控制器中与数据库对话的另一个函数时，我在该函数的开头再做一个println并改为nil。

我已尝试将其作为

传递

(read-string x)
(boolean (Boolean/valueOf x))
(Boolean/valueOf x)

无济于事。

可能导致它的一件事（但我不知道为什么）是我通过身份验证包装请求：

(auth? request #(create x y z))

(create)函数在数据库中创建记录。

无论我尝试过什么，我都无法成为true。

编辑：更完整的代码

CONTROLLER

(defn auth? [request callback-true & [callback-false]]
  (println (callback-true))
  (let [login-response (auth/login request)]
    (if (and (not (string? login-response))
             login-response)
      (callback-true)
      (if callback-false 
        (callback-false)
        (json-response (str "{\"auth\":" login-response "}"), 401)))))

(defn create [user logged-in-user body public?]
  (if (= logged-in-user user)
    (json-response (post-view/single-post (post/create user body public?)))
    (json-response "{\"auth\":\"can't create post under different logged in user\"}" 401)))

(defroutes routes
  ....
  (PUT "/api/:user/new" request
       (println request)
       (auth? request
              #(create (:user (request :params))
                       (:user (request :session))
                       (:body (get-params request))
                       (:public (get-params request)))))
  ....
)

MODEL

(defn create [username body public?]
  (println public?)
  (when-not (and 
              (str/blank? body)
              (str/blank? username))
  (let [user-id (:id (get-id-from-username username))
        new-post-id
        (:id 
            (sql/with-connection db
                (sql/insert-values :post
              [:usr_id :body :public] [user-id body (Boolean/valueOf public?)])))]
    (by-id new-post-id))))

请勿两次致电get-params。（request：body）返回一个无法读取两次的流。

Clojure中的奇怪布尔行为，表单数据中有复选框
