我有一个应用程序可以将图像上传到我的公司服务器我正在使用 koush Ion 进行上传现在问题是上传本身有效图像正在上传到服务器但我没有收到来自服务器的弹出响应说上传成功等。在我从 APACHE 切换到 Ion 之前，这些响应之前有效

在我单击 Upload 之后似乎没有任何反应但是图像已上传到服务器，但服务器没有响应，通常弹出 Upload Success 等。响应的代码在 ASP 文件中

上传活动

该请求返回一个字符串 =“我在”，但回调需要 JsonObject。您的服务器必须返回 json 格式字符串。

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

            }
        });
