我的應用未從上傳的服務器中獲取響應

Question

我有一個將圖片上傳到公司服務器的應用程序，我正在使用koush Ion進行上傳，現在的問題是上傳本身可以正常工作，但圖片正在上傳到服務器，但是我沒有從服務器收到彈出式回應，說上傳成功等等。在我從APACHE切換到Ion之前，響應以前已經起作用

單擊“上傳”后，似乎什么也沒發生，但是圖像已上傳到服務器，但是服務器沒有響應，並且具有“成功上傳”等常規彈出窗口。響應的代碼位於ASP文件中

該請求返回一個字符串=“我在”，但是回調需要JsonObject。 您的服務器必須返回json格式的字符串。

Ion.with(this)
        .load(myURL)
        .setMultipartFile("SP-LOG", "image/jpeg", imageFile)
        .asJsonObject()
        .setCallback(new FutureCallback<JsonObject>() {
            @Override
            public void onCompleted(Exception e, JsonObject result) {

            }
        });
