使用SPA登錄reactjs后如何重定向到主頁

Question

我的問題：點擊登錄后，我的頁面沒有重定向到主頁但仍然停留在登錄頁面，即使簽入應用程序我已經成功登錄，我必須在登錄后按 F5 讓一切恢復正常。 在reactjs中使用SPA時如何點擊登錄可以重定向到主頁

謝謝

函數提交

 onSubmit: async () => { const loginData = await loginUser(values); console.log(loginData); if (loginData.success) { navigate('/dashboard/app', { replace: true }); } else console.log(values); }

路由器：

 import { useContext } from 'react'; import { Navigate, useRoutes } from 'react-router-dom'; // layouts import DashboardLayout from './layouts/dashboard'; import LogoOnlyLayout from './layouts/LogoOnlyLayout'; // import Login from './pages/Login'; import Register from './pages/Register'; import DashboardApp from './pages/DashboardApp'; import Products from './pages/Products'; import Blog from './pages/Blog'; import User from './pages/User'; import NotFound from './pages/Page404'; // import { AuthContext } from './contexts/AuthContext'; // ---------------------------------------------------------------------- export default function Router() { const { authState: { authLoading, isAuthenticated } } = useContext(AuthContext); let body; if (authLoading) { body = 0; } else if (isAuthenticated) { body = 1; } else { body = 2; } return useRoutes([ { path: '/dashboard', element: <DashboardLayout />, children: [ { element: body === 1? <Navigate to="/dashboard/app" replace />: <Navigate to="/login" /> }, { path: 'app', element: body === 1? <DashboardApp />: <Navigate to="/login" /> }, { path: 'user', element: body === 1? <User />: <Navigate to="/login" /> }, { path: 'products', element: body === 1? <Products />: <Navigate to="/login" /> }, { path: 'blog', element: body === 1? <Blog />: <Navigate to="/login" /> } ] }, { path: '/', element: <LogoOnlyLayout />, children: [ { path: 'login', element: body === 1? <Navigate to="/dashboard" />: <Login /> }, { path: 'register', element: body === 1? <Navigate to="/dashboard" />: <Register /> }, { path: '404', element: <NotFound /> }, { path: '/', element: body === 1? <Navigate to="/dashboard" />: <Navigate to="/login" /> }, { path: '*', element: <Navigate to="/404" /> } ] }, { path: '*', element: <Navigate to="/404" replace /> } ]); }

Answer 1

當您想重定向到另一個路由時：

import { useHistory } from "react-router-dom";

const Login = () => {

let history = useHistory(); //add this line

   onSubmit: async () => {
     const loginData = await loginUser(values);
       console.log(loginData);
       if (loginData.success) {
         history.push('/dashboard/app'); //add this instead
       } else console.log(values);
     }
   }

我不認為導航存在於 react-router-dom 中。 你在考慮重定向嗎？
