HarmonyOS 如何在HarmonyOS进行一个带文件上传的post请求？

Question

/**
 * imgPath是一个图片地址
 **/
public void test(String imgPath) {
  String url = "https://app.ccjg.com/upload";
  RequestBody requestBody = new MultipartBody.Builder()
    .setType(MultipartBody.FORM)
    .addFormDataPart("range", "searchIndex")
    .addFormDataPart("from", "pc")
    .addFormDataPart("tn", "pc")
    .addFormDataPart("image_source", "PC_UPLOAD_FILE")
    .addFormDataPart("sdkParams", "test")
    .addFormDataPart("image", "filename",
      RequestBody.create(MediaType.parse("multipart/form-data"), new File(imgPath)))
    .build();
  Request request = new Request.Builder()
    .url(url)
    .removeHeader("User-Agent")
    .addHeader("Accept-Language", ACCEPT_LANGUAGE)
    .addHeader("User-Agent", USER_AGENT_WINDOWS)
    .post(requestBody)
    .build();
  //下面是okhttp网络请求，可否给一份axios的请求示例
  Call call = NetWorkHelper.getInstance().getOkHttpClient().newCall(request);
  call.enqueue(new Callback() {
    @Override
    public void onFailure(Call call, IOException e) {
      e.printStackTrace();
    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
      try {

      } catch (Exception e) {
        e.printStackTrace();
      }
    }
  });
}
