android最简单的图片上传,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() {

@Override

public void onSuccess(UploadBean bean) {

if (bean.isStatus() || bean.getMsg().equals("success"))

getV().onUpload(bean.getImage());

}

@Override

public void onError(int code, String msg) {

}

}));

private RequestBody getRequstBody(String path) {

MultipartBody.Builder builder = new MultipartBody.Builder().setType(MultipartBody.FORM);

Mapparameters = new HashMap<>();

File file = new File(path);

MLog.e("==============file=="+file.getAbsolutePath());

parameters.put("file",file);

parameters.put("user_id", UserInfoManager.getInstance().getUserId());

SetkeySet = 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!
