android - okhttp 带文件名的多部分图片上传

Question

我正在尝试将图像从 Android 手机上传到服务器。这是我到目前为止所做的

  OkHttpClient client = new OkHttpClient();
            MultipartBuilder builder = new MultipartBuilder();


builder.type(MultipartBuilder.FORM).addPart(RequestBody.create(MediaType.parse("application/json; charset=utf-8"), requestPackage.getJsonParam().toString()));
            for (int i = 0; i < requestPackage.getPics().size(); i++) {
                builder.addPart(RequestBody.create(MediaType.parse("image/png"/* + i*/), new File(URI.create(requestPackage.getPics().get(i)))));
            Log.i("image to upload",URI.create(requestPackage.getPics().get(i)).toString());
            }
            requestBody = builder.build();
     Request request = new Request.Builder().url(requestPackage.getUri()).post(requestBody).build();
            try {
                response = client.newCall(request).execute();
                if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
    //            System.out.println(response.body().string());
                return response.body().string();
            } catch (IOException e) {
                e.printStackTrace();
            }

我如何为不同的部分添加名称。因为如果它们没有名称( key )那么服务器端人员将如何存储它？

获取 OkHttp 2.1，并使用 MultipartBuilder.addFormDataPart() 将文件名作为参数。
