基于axios和react的httpclient封装

import axios from 'axios';
import { message } from 'antd';
import React from 'react';

/**
 * 支持常用的请求方法包括 ['get', 'delete', 'head', 'post', 'put', 'options']
 * 对外暴露的实例如下
 * 1:HttpClient 满足全局loading样式(需要配合mobx的store管理全局状态)
 * 2:HttpClientOnly 满足不展示对应loading
 * 3:HttpClientPart 满足局部loading(需要配合mobx的store管理全局状态)
