Cloudsight Api 对 Android 平台上的图像上传提供空响应

我正在尝试上传图像"https://api.cloudsightapi.com/image_requests https://api.cloudsightapi.com/image_requests"但在请求调用之后，我将所有字段都设为 null 到响应中。即状态、名称、令牌等。我正在使用 Retrofit 2.0.1 进行请求调用。

Code:

RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);

MultipartBody.Part body =
MultipartBody.Part.createFormData("image_request[image]", file.getName(), requestFile);

String descriptionString = "en-US";
RequestBody description = RequestBody.create(MediaType.parse("multipart/form-data"), descriptionString);

**API CALL:**
@Multipart
    @POST("https://api.cloudsightapi.com/image_requests")
    Call<FileUploadResponse> uploadPhoto(
            @Header("Authorization") String authorisation,
            @Part("image_request[locale]") RequestBody description,
            @Part MultipartBody.Part file);

我将所有字段放入response.body null 中。请帮忙。

像这样上传图像文件：

File file = // initialize file here

MultipartBody.Part filePart = MultipartBody.Part.createFormData("file", file.getName(), RequestBody.create(MediaType.parse("image/*"), file));

Call<MyResponse> call = api.uploadPhoto(filePart);//u can send other parameters along with the filePart depending upon ur method signature
