如何访问子组件中的父组件方法，如下所示

Question

//this is the parent component in ibios.js file

import  React from 'react';
import ReactDOM from 'react-dom';
import axios from 'axios';

class ibios extends React.Component{
  constructor(){
        super();
        this.sate={};
        this.get = this.get.bind(this);
    }
 get(ur,apiurl,prametars){
  prametars=prepareHeaderRequest;
    return axios.get(url+apiUrl,{params:prametars})
            .then(function(response){
                console.log(response.data);
            });
    }
    render(){
        return(
            <p>hi...</p>
            );
   }
}

//this is the child component chart component.js file

import React from 'react';
import ibios from '../ibios/IBIOS';
import ChartComponent from './chartcomponents';

class BarChartComponent extends ChartComponent{
  constructor(props){
        super(props)
        this.state={};  
    }
   componentDidMount(){
      //example
       var url="http://localhost:9090",apiUrl="/reports",prametrs={xyz:ramki};
     var retriveResponse=this.ibios.get(url,apiUrl,prametrs)
     console.log(retriveResponse);
   }
  render(){
     return(<p>hi......</p>);
  }
}

//我在ibos.get()?........................................................................................中只写过一次axios方法，以及如何继承每个组件以及如何通过axios直接获取响应............................................................................................................................................................................................................................
