java - 如何使用 Retrofit 发出请求

Question

This is actual image of POST request [使用Android Retrofit上传图片，如何使用Retrofit发出Multipart请求][2]

我使用 Retrofit 发送多个图像文件以及字符串数据，但在服务器端字符串数据丢失

我的保存注册API /*Save register*/
@Multipart
@POST("Events/SaveRegistration")
Call<ModelRegisterMember> saveRegister(
@Part List<MultipartBody.Part> files, @Query("data") String memberData
);
// body of request
private void uploadMemberInfo(List parts, ModelMakeMemberRegister allMembers) {

    ProgressDialog progressDialog = new ProgressDialog(mContext);
    progressDialog.setMessage("Please Wait...");
    progressDialog.setCancelable(false);
    progressDialog.show();


    ApiInterface apiInterface = ApiClient.getClient().create(ApiInterface.class);
    Call<ModelRegisterMember> call = apiInterface.saveRegister(parts, new Gson().toJson(allMembers));


    Log.e("Req", call.request().toString());
    Log.e("Body", call.request().body().toString());
    Log.e("Body", call.request().headers().toString());
    Log.e("json", new Gson().toJson(allMembers));
    call.enqueue(new Callback<ModelRegisterMember>() {
        @Override
        public void onResponse(Call<ModelRegisterMember> call, Response<ModelRegisterMember> response) {
            progressDialog.dismiss();
            MyUtils.showToast(mContext, response.body().getMessage());
        }
        @Override
        public void onFailure(Call<ModelRegisterMember> call, Throwable t) {
            Log.e("err", t.toString());
            progressDialog.dismiss();
        }
    });


}`

fun uploadFile(@Url url:String, @Part("AppGuid") guid:RequestBody,
              @Part("UserGuid") uuid:RequestBody? = null,
              @Part("DeviceToken") token:RequestBody,
              @Part("UserAppGuid") uAppGuid:RequestBody,
              @Part("FileName") fileName:RequestBody,
              @Part("FileType") fileType:RequestBody, @Part file: MultipartBody.Part): Call<JsonElement>
