Android Retrofit 图片上传的最简单和明白的实现方式

RetrofitRequestHelper.getInstance().getRetrofit(configChatRoomDataBean.getHttp()).create(IRetrofitService.class).upload("/psr/files",getRequstBody(path)).subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread( )).as(bindLifecycle()).subscribe(new ResponseObserver<>(new ResponseCallBack() {@Overridepublic void onSuccess(UploadBean bean) {if (bean.isStatus() || bean.getMsg().equals("success"))getV().onUpload(bean.getImage());}@Overridepublic void onError(int code, String msg) {}}));private RequestBody getRequstBody(String path) {MultipartBody.Builder builder = new MultipartBody.Builder().setType(MultipartBody.FORM);Map parameters = new HashMap<>();File file = new File(path);MLog.e("==============file=="+file.getAbsolutePath());parameters.put("file",file);parameters.put("user_id", UserInfoManager.getInstance().getUserId());Set keySet = parameters.keySet();for (String key : keySet){Object param = parameters.get(key);if (param instanceof File){File temfile = (File) param;builder.addFormDataPart(key, temfile.getName(), RequestBody.create(MediaType.parse("*/*"), temfile));} else{String value = String.valueOf(param);if(!StringUtils.isEmpty(value))builder.addFormDataPart(key, value);}}MLog.e("path=="+path);return builder.build();}

注意事项:

请求回来的bean一定要写对,不然请求成功了,响应是200 但是你bean中没有任何数据.我曾经就踩过这个坑.就因为后台临时改了bean,又没有更新文档,结果响应成功了,就是没有数据出来!
