WCF Rest用于处理Retrofit发送数据

Question

我想通过改造发送一些数据，包括图像和三个字符串， 如果有人可以帮助我，我的WCF服务器端方法签名应如何处理这些发布的数据？

以下代码是我的客户端改装（虽然我不确定它是否写得很好）。

        @Multipart
        @POST("PostBanderolDataJSON")
        Call<MyResponse> PostData(@Part("banderolNr") RequestBody banderolNr, @Part("pharmacy") RequestBody pharmacy, @Part("place") RequestBody place, @Part("report_pic\"; filename=\"rp.png\" ") RequestBody file);
    }

 Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl(RetrofitApiInterface.BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
            RetrofitApiInterface api = retrofit.create(RetrofitApiInterface.class);

            RequestBody reportImage = RequestBody.create(MediaType.parse("image/jpeg"), ImagePath);
            RequestBody banderoNr = RequestBody.create(MediaType.parse("text/plain"), etBanderolNr.getText().toString());
            RequestBody pharmacy = RequestBody.create(MediaType.parse("text/plain"), Pharmacy.getText().toString());
            RequestBody place = RequestBody.create(MediaType.parse("text/plain"), Place.getText().toString());

            Call<MyResponse> call = api.PostData(banderoNr,pharmacy,place,reportImage);

            call.enqueue(new Callback<MyResponse>() {
                @Override
                public void onResponse(Call<MyResponse> call, Response<MyResponse> response) {
                    if (response.isSuccessful()) {
                        if (!response.body().error) {
                            Toast.makeText(getApplicationContext(), "Data Sent Successfully...", Toast.LENGTH_LONG).show();
                        } else {
                            Toast.makeText(getApplicationContext(), "Some error occurred...", Toast.LENGTH_LONG).show();
                        }
                        progress.dismiss();
                    }
                    else{
                        Toast.makeText(getApplicationContext(),"Something went wrong with the request to the server !",Toast.LENGTH_SHORT).show();
                    }
                }

                @Override
                public void onFailure(Call<MyResponse> call, Throwable t) {
                    progress.dismiss();
                    Toast.makeText(getApplicationContext(), t.getMessage(), Toast.LENGTH_SHORT).show();
                }
            });
