【问题描述】:
我正在使用嵌套路由创建仪表板。但是当我尝试单击链接时,浏览器上的 URL 确实发生了变化,但 useLocation 挂钩没有更新,因此我的 useEffect 挂钩不会被触发以重新加载数据。
这是我的App主要路线:
function App() {
return (
<Router>
<Header />
<Switch>
<Route path="/login" component={ Login } />
<ProrectedRoute exact path="/" component={ Home } />
<ProrectedRoute path="/blogs/:title" component={ BlogPage } />
<ProrectedRoute path="/new" component={ NewBlog } />
<ProrectedRoute path="/dashboard/:part" component={ UserDashboard } />
<ProrectedRoute path="/:name" component={ ProfilePage } />
</Switch>
<Footer />
</Router>
);
}
这是我的仪表板:
export const UserDashboard = () => {
const dispatch = useDispatch();
const location = useLocation();
useEffect(() => {
switch(location) {
case '/dashboard/posts':
dispatch(getOwnPosts());
break;
case '/dashboard/bookmarks':
dispatch(getBookmarkPosts());
break;
case '/dashboard/followings':
break;
default:
break;
};
}, [location]);
return (
<div className="dashboard">
<Router>
<div className="dashboard__sidebar">
<Link to="/dashboard/posts">Your posts</Link>
<Link to="/dashboard/bookmarks">Your bookmarks</Link>
<Link to="/dashboard/followings">Your followings</Link>
</div>
<div className="dashboard__main">
<Switch>
<Route exact path="/dashboard/posts">
<BlogRecommendationList selector={selectUserPosts} />
</Route>
<Route exact path="/dashboard/bookmarks">
<BlogRecommendationList selector={selectUserBookmarkedPosts} />
</Route>
</Switch>
</div>
</Router>
</div>
)
}
