Retrofit + Rxjava 多图片上传

方法1：
@Multipart
@POST(“接口”)
Observable updateImages(@Part List parts);

List paths = new ArrayList();
MultipartBody.Builder builder = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)//表单类型
                .addFormDataPart("uuid", uuid)
                .addFormDataPart("token", token)
                .addFormDataPart("orderNum", orderNum)
                .addFormDataPart("bankCardNum", getEditTextString(etBankNum))
                .addFormDataPart("payType", payType)
                .addFormDataPart("fuyouNo", getEditTextString(etSerialNumber))
                .addFormDataPart("type", "pay")
                .addFormDataPart("id", id)
                .addFormDataPart("bankName", getEditTextString(etBankInformation));

        List parts = new ArrayList<>();

        for (String imgPath : paths) {
            File file = new File(imgPath);
            RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
            builder.addFormDataPart("files", file.getName(), requestFile);//files 后台接收图片流的参数名
            parts = builder.build().parts();
        }

            toFileSize(fileSize);
            images.put("files" + file.getName(), RequestBody.create(MediaType.parse("multipart/form-data"), file));
        }
