###1.自定义model继承BaseModel ###2.自定义presenter继承BasePresenter ###3.Fragment/Activity继承BaseView，重写四个方法： showDialog() ：显示进度条 hideDialog() ：隐藏进度条 respense(int requestCode, String url, String data) ：成功返回数据 fail(Request request, Exception e) ：请求失败
###1.get请求 requestDataByGet (requestCode, url, headers, params, onResponse)
###2.post请求 requestDataByPost (requestCode, url, headers, params, onResponse)
###3.post上传表单文件 requestDataByPostFormFiles (requestCode, url, headers, params, keys, files, onResponse)
###4.post上传文件 requestDataByPostFile (requestCode, url, headers, params, file, onResponse)
###5.get下载文件 downloadFile (requestCode, url, headers, params, path, fileName, onResponse)
###6.post上传json字符串 requestDataByPostJson(requestCode, url, headers, params, contentJson, onResponse)
requestCode ：请求码(int)
url ：url(String)
headers ：请求头(HashMap)
params ：请求参数(HashMap)
file ：文件(File)
files ：多个文件(List)
path ：路径(String)
fileName ：文件名(String)
onResponse ：回掉
###1.model public class BrandModel extends BaseModel {
