javascript">  const [param, setParam] = useSearchParams()const params = Object.fromEntries(param.entries());console.log(params);

如果是params的话,就是用返回一个对象, 

javascript">  const p = useParams()console.log(p);

为什么是对象?难道param还能有2个字段? 还真是! 

给2个占位符

javascript">{path: "/login/:uid/:uuid",element: <Login />}

 

javascript">  <button onClick={() => navigate('/login/3/6?age=18&name=小明')}>点击</button>

打印

javascript">{"uid": "3","uuid": "6"
}
