react-http方法查询和参数

Question

我做了这段代码

export default class App extends Component {
  render() {
    return (
      <Request
        url='http://localhost:3000/mz/api/lookup?a=3&b=6'
        method='get'
        accept='application/json'
        verbose={true}>
        {({error, result, loading}) => {
            console.log(result,"helllo")
            if (loading) {
              return <div>loading...</div>;
            } else {
              return <div>{ JSON.stringify(result.text) }</div>;
            }
          }
        }
      </Request>
    );
  }
}
render(<App/>,document.querySelector('.container'));

如何向此代码添加查询或参数我希望a和b的值是更改，因为我输入我的意思是它就像params或在url中查询，值在用户点击路径时输入
