编写访客和授权页面的最佳方法取决于具体的需求和技术栈。以下是一些常见的解决方法,其中包含了代码示例:
import React from 'react';
import { BrowserRouter as Router, Route, Redirect } from 'react-router-dom';
const AuthRoute = ({ component: Component, auth, ...rest }) => (
auth ? (
) : (
)
}
/>
);
const GuestRoute = ({ component: Component, auth, ...rest }) => (
!auth ? (
) : (
)
}
/>
);
const App = () => (
);
const Dashboard = () => Welcome to the dashboard!
;
const Login = () => Please log in to continue.
;
const isLoggedIn = true; // 根据实际的认证状态进行设置
export default App;
const express = require('express');
const passport = require('passport');
const app = express();
app.get('/dashboard', isAuthenticated, (req, res) => {
res.send('Welcome to the dashboard!');
});
app.get('/login', isNotAuthenticated, (req, res) => {
res.send('Please log in to continue.');
});
// 身份验证中间件
function isAuthenticated(req, res, next) {
if(req.isAuthenticated()) {
return next();
}
res.redirect('/login');
}
// 非身份验证中间件
function isNotAuthenticated(req, res, next) {
if(!req.isAuthenticated()) {
return next();
}
res.redirect('/dashboard');
}
// 使用Passport.js进行身份验证的路由
app.post('/login', passport.authenticate('local', {
successRedirect: '/dashboard',
failureRedirect: '/login',
}));
app.listen(3000, () => {
console.log('Server started on port 3000');
});
总结 以上是一些编写访客和授权页面的常见方法。具体的实现方法取决于您的具体需求和使用的技术栈。您可以根据这些示例进行自定义和扩展以满足您的要求。
