Answer 1

您将对象传递给getUser 而不是string，因此您应该将urlName 作为useParams 的属性。

const { urlName } = useParams()

您还需要将key/value 属性传递给路由组件的子组件，如下所示：

// set param with unique name to route's path
<Route path="/user/:urlName" />

// access the 'key/value' params after transition to the route component inside it's children
const {urlName} = useParams()

这样，如果您想拥有动态路由路径，您可以将 :urlName 设置为您的 Link 组件，例如：

const userName = "Johb"
<Link to={`/user/${userName}`}
