我遵循使用 clojure 进行图书 Web 开发的示例代码,第 2 版,我在使用 google 关闭时上传文件时遇到问题。
我用 Swagger 测试文件上传,它响应我200 ok,我认为错误来自上传文件!功能。(见下文)。
但是我查看了closure api doc,似乎我使用了正确的功能。
所以我遇到了麻烦,我不知道为什么它不起作用......
我需要有人帮助。这是我的代码(我对 ui 组件使用语义 ui):
(defn upload-file! [upload-form-id status]
(reset! status nil)
(let [io (IframeIo.)]
(gev/listen
io goog.net.EventType.SUCCESS
#(reset! status [c/success-message "file uploaded successfully"]))
(gev/listen
io goog.net.EventType.ERROR
#(reset! status [c/warning-message "failed to upload the file"]))
(.setErrorChecker io #(= "error" (.getResponseText io)))
(.sendFromForm io (.getElementById js/document upload-form-id) "/upload")))
(defn upload-form []
(let [status (atom nil)
form-id "upload-form"]
(fn []
[c/modal
[:div "Upload File"]
[:div
(when @status @status)
[:div.ui.form
{:id form-id
:enc-type "multipart/form-data"
:method "POST"}
[:label {:for "file"} "select an image for upload"]
[:input {:id "file"
:name "file"
:type "file"}]]]
[:div
[:button.ui.primary.button
{:on-click #(upload-file! form-id status)}
"upload"]
[:button.ui.red.button
{:on-click #(do
(.modal (js/$ ".ui.modal") "hide")
(reset! status nil))}
"Cancel"]]
"upload"])))
组件:
(defn modal [header content footer id]
[:div.ui.modal
{:id id}
[:div.header header]
[:div.content content]
[:div.actions footer]])
(defn success-message [content]
[:div.ui.green.message
[:div.header content]])
