注意点：
方案一中：map.put(“files\”; filename=\”” + file.getName(), requestBody);
方案二中：builder.addFormDataPart(“files”, file.getName(), imageBody)；
需与服务器一制,如：Content-Disposition: form-data; name=”files”; filename=”1.jpg”）

方案一：@Multipart@POST("upload/v1/images")Observable<HttpResult<String>> uploadImages(@Header("token") String token, @Part("appkey") RequestBody appkey, @Part("sign") RequestBody sign,                                            @PartMap() Map<String, RequestBody> map);/** * 上传 * @param compressFile 需要上传的文件 */private void upload(List<File> compressFile) {    LogUtil.e(TAG, "uploadImages: 开始上传...");    //多张图片    Map<String, RequestBody> map = new HashMap<>();    if (compressFile != null && !compressFile.isEmpty()) {        for (int i = 0; i < compressFile.size(); i++) {            File file = compressFile.get(i);            LogUtil.e(TAG, "upload: path:  " + file.getAbsolutePath());            RequestBody requestBody = RequestBody.create(MediaType.parse("multipart/form-data"), file);            map.put("files\"; filename=\"" + file.getName(), requestBody);        }    }    RequestBody appkey = RequestBody.create(null, Api.APPKEY);    RequestBody sign   = RequestBody.create(null, Api.SIGN);    mApiWrapper.uploadImages(appkey, sign, map)            .subscribeOn(Schedulers.io())            .observeOn(AndroidSchedulers.mainThread())            .subscribe(new Observer() {         @Override         public void onSubscribe(@NonNull Disposable d) {         }         @Override         public void onNext(@NonNull Object t) {                LogUtil.e(TAG, "uploadImages: 上传成功");          }         @Override         public void onError(@NonNull Throwable e) {         }         @Override         public void onComplete() {         }});}方案二：@Multipart@POST("upload/v1/images")Observable<HttpResult<String>> uploadImages1(@Header("token") String token, @Part List<MultipartBody.Part> partList);/** * 上传 * @param compressFile 需要上传的文件 */private void upload(List<File> compressFile) {    LogUtil.e(TAG, "uploadImages: 开始上传...");    //多张图片    MultipartBody.Builder builder = new MultipartBody.Builder()            .setType(MultipartBody.FORM)//表单类型            .addFormDataPart("appkey", Api.APPKEY)            .addFormDataPart("sign", Api.SIGN);    for (int i = 0; i < compressFile.size(); i++) {        File        file      = compressFile.get(i);        RequestBody imageBody = RequestBody.create(MediaType.parse("multipart/form-data"), file);        builder.addFormDataPart("files", file.getName(), imageBody);    }    List<MultipartBody.Part> parts = builder.build().parts();    mApiWrapper.uploadImages(parts)            .subscribeOn(Schedulers.io())            .observeOn(AndroidSchedulers.mainThread())            .subscribe(new Observer() {         @Override         public void onSubscribe(@NonNull Disposable d) {          }         @Override         public void onNext(@NonNull Object t) {                LogUtil.e(TAG, "uploadImages: 上传成功");          }         @Override         public void onError(@NonNull Throwable e) {          }         @Override         public void onComplete() {         }});}
