我有一个JSON文件,并且在此JSON文件中有一个对象URI,并且此URI包含一个JSON文件,我正在尝试从URI JSON文件中获取数据,但我无法同时附加我的代码和JSON文件

class Details extends Component {
    constructor(props){
        super(props);

        this.state = {
            question: null,
          };
    }




    componentDidMount(){
     const { match: { params } } = this.props;

       axios.get(params.uri).then((res)=>{
         const question = res.data[0]['uri'];
         axios.get(question).then((qRes) => {
           console.log(qRes); //will return the data from the second uri
         })
         console.log(question);
         this.setState({ question });
       })

   }

这是JSON数据,其中对象URI包含一个JSON文件,因此我想从URI JSON文件中获取数据。
