我正在使用 AngularJS 资源来基本上 $.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)))

true当我从我的路由处理程序中 println时,当复选框被选中时,我会得到一个很好的结果:

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

但是,当我将参数(即不是 println)传递给控制器​​中与数据库通信的另一个函数时,我在该函数的开头执行另一个 println 并nil改为获取。

我试过把它作为

(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)是我通过如下身份验证包装请求:

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

(create)函数在数据库中创建一条记录。

true无论我尝试了什么,我都无法做到。

编辑:更完整的代码

控制器

(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)))))
  ....
)

模型

(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))))

不要打get-params两次电话。(request :body) 返回一个无法读取两次的流。
