最近手头事比较多，抽个空把之前系列也补充一下。

先回顾下之前的

今天要说的是文件上传

1.单图上传

首先ApiServer，要使用Multipart 注解

//上传图片(私有接口)
  @POST("index.php/PrivateApi/Goods/uploadPic")
  @Multipart
  Observable<BaseListModel<String>> upLoadImg(@Part MultipartBody.Part parts);

然后是Presenter

 public void upLoadImg(String path) {
        File file = new File(path);
        RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
        MultipartBody.Part filePart = MultipartBody.Part.createFormData("headimg", file.getName(), requestFile);
        addDisposable(apiServer.upLoadImg(filePart), new BaseObserver<BaseListModel<String>>(baseView, true) {
            @Override


            public void onSuccess(BaseListModel<String> o) {
                baseView.onUpLoadSucc(o.getData());
            }

            @Override
            public void onError(String msg) {
                baseView.showError(msg);
            }
        });
    }

成功后做个提示就好

2.多图上传

ApiServer

 @POST("index.php/PrivateApi/Goods/uploadPic")
    @Multipart
    Observable<BaseListModel<String>> upLoadImg(@Part MultipartBody.Part[] parts);

Presenter

 public void upLoadImg(ArrayList<String> media) {
        if (media == null) {
            return;
        }

        MultipartBody.Part[] parts = new MultipartBody.Part[media.size()];
        int cnt = 0;
        for (String m : media) {
            File file = new File(m);
            RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
            MultipartBody.Part filePart = MultipartBody.Part.createFormData("headimg[]", file.getName(), requestFile);
            parts[cnt] = filePart;
            cnt++;
        }

     
        addDisposable(apiServer.upLoadImg(parts), new BaseObserver<BaseListModel<String>>(baseView, true) {
            @Override


            public void onSuccess(BaseListModel<String> o) {
                baseView.onUpLoadSucc(o.getData());
            }

            @Override
            public void onError(String msg) {
                baseView.showError(msg);
            }
        });
    }

3.文件和普通参数混合

ApiServer

  //上传图片(私有接口)
    @POST("index.php/PrivateApi/Goods/uploadPic")
    @Multipart
    Observable<BaseListModel<String>> upLoadImg(@Part MultipartBody.Part[] parts, @Part("APP_KEY") RequestBody APP_KEY, @Part("APP_TOKEN") RequestBody APP_TOKEN);

Presenter

 public void upLoadImg(ArrayList<String> media) {
        if (media == null) {
            return;
        }

        MultipartBody.Part[] parts = new MultipartBody.Part[media.size()];
        int cnt = 0;
        for (String m : media) {
            File file = new File(m);
            RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
            MultipartBody.Part filePart = MultipartBody.Part.createFormData("headimg[]", file.getName(), requestFile);
            parts[cnt] = filePart;
            cnt++;
        }

        RequestBody appkey = RequestBody.create(MediaType.parse("multipart/form-data"), AppConstant.APP_KEY);
        RequestBody apptoken = RequestBody.create(MediaType.parse("multipart/form-data"), UserImpl.getAppToken());
//
        addDisposable(apiServer.upLoadImg(parts, appkey, apptoken), new BaseObserver<BaseListModel<String>>(baseView, true) {
            @Override


            public void onSuccess(BaseListModel<String> o) {
                baseView.onUpLoadSucc(o.getData());
            }

            @Override
            public void onError(String msg) {
                baseView.showError(msg);
            }
        });
    }

至此，使用Retrofit文件上传暂时告一段落。
