retrofit+okhttp+rxjava

1.上传文件

 @Multipart
    @POST(API_P_PERSONALDATA)
    Flowable<FileBean> uploadfile(@PartMap Map<String, RequestBody> files);

//上传多张图片，文件，单张图片，单个语音等
    public void uploadFile( ResourceSubscriber<FileBean> subscriber, List<File> files, File picfile, File voiceFile,String name) {
        LinkedHashMap<String, RequestBody> bodyMap = new LinkedHashMap<>();
        if(files!=null&&files.size()>0){
            for (int i = 0; i < files.size(); i++) {
                bodyMap.put("pic"+"["+i+"]\"; filename=\""+files.get(i).getName(),RequestBody.create(MediaType.parse(Constant.IMG_MEDIATYPE),files.get(i)));
            }
        }
        if (voiceFile != null) {
            bodyMap.put("fileVoice\"; filename=\"" + voiceFile.getName(), RequestBody.create(MediaType.parse(Constant.MULTIPART_FORM_DATA), voiceFile));
        }
        if(picfile!=null){
            bodyMap.put("pic\"; filename=\""+picfile.getName(),RequestBody.create(MediaType.parse(Constant.IMG_MEDIATYPE),picfile));
        }

        bodyMap.put("token",RequestBody.create(MediaType.parse(Constant.TEXT_FROMDATA),UserInfoBean.getInstance().getToken()));
        bodyMap.put("id",RequestBody.create(MediaType.parse(Constant.TEXT_FROMDATA),UserInfoBean.getInstance().getUid()));

        if(!TextUtils.isEmpty(name)){
            bodyMap.put("name",RequestBody.create(MediaType.parse(Constant.TEXT_FROMDATA),name));
        }
        Flowable observable = httpService.uploadfile(bodyMap);
        toSubscribe(observable, subscriber);
    }

2.返回字符串

 @FormUrlEncoded
    @POST(API_P_INDEX)
    Flowable<ResponseBody> pIndex(@FieldMap Map<String, String> map);

public void pIndex(Context c, ListCompositeDisposable compositeSubscription, SubscriberListener<ResponseBody> subscriberOnNextListener,boolean isShow) {
    Map<String,String> params = new HashMap<>();
    params.put("token", UserInfoBean.getInstance().getToken());
    params.put("id",UserInfoBean.getInstance().getUid());
    Flowable<ResponseBody> observable = httpService.pIndex(StringUtils.sortMapByValue2(params));
    ResourceSubscriber subscriber = new ProgressSubscriber(subscriberOnNextListener, c, -1,isShow);
    toSubscribe(observable, subscriber);
    compositeSubscription.add(subscriber);
}

private void getData(){
    if(!UserInfoBean.getInstance().isLogin()){
        return;
    }
    HttpMethods.getInstance().pIndex(mContext, getComp(), new SubscriberListener<ResponseBody>() {
        @Override
        public void onNext(ResponseBody responseBody, int httpcode) {
            try {
                String data = responseBody.string().trim();
                SimpleBean bean = GsonUtil.GsonToBean(data,SimpleBean.class);
                if(bean.state== HttpMethods.HTTP_SUCCESS){
                    PersonInfoBean bean1 = GsonUtil.GsonToBean(data,PersonInfoBean.class);
                   




                }else{
                    ToastUtil.makeShortText(mContext,bean.message);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }

        }

        @Override
        public void onError(int httpcode) {

        }
    },false);
}

3.下载文件

/**
 * 下载文件
 */
private void loadFile() {
    initNotification();
    if (retrofit == null) {
        retrofit = new Retrofit.Builder();
    }
    Call<ResponseBody> responseBodyCall = retrofit.baseUrl(BASE_URL)
            .client(initOkHttpClient())
            .build()
            .create(HttpService.class)
            .loadFile(url);
    downCalls.put(url,responseBodyCall);
    responseBodyCall.enqueue(new FileCallback(new ListCompositeDisposable(),APK_DOWN_PATH, filename) {

                @Override
                public void onSuccess(File file) {
                    //Log.e("zs", "请求成功");
                    // 安装软件
                    cancelNotification();
                    if(filename.endsWith(".apk")){
                        installApk(file);
                    }
                }
                @Override
                public void onLoading(long progress, long total) {
                   // Log.e("zs", progress + "----" + total);
                    if(total==0){
                        total = 100;
                    }
                    updateNotification(progress * 100 / total);
                }

                @Override
                public void onFailure(Call<ResponseBody> call, Throwable t) {
                    Log.e("zs", "请求失败");
                    cancelNotification();
                }
            });
}
