在React Redux中添加受保护的路由,通常涉及到几个关键步骤:设置路由、创建认证状态管理、以及保护路由的逻辑实现。下面我将详细介绍这些步骤。
首先,你需要设置基本的路由配置。使用react-router-dom
库来实现。
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import Home from './Home';
import Login from './Login';
import ProtectedRoute from './ProtectedRoute';
import Dashboard from './Dashboard';
function App() {
return (
<Router>
<Switch>
<Route path="/login" component={Login} />
<ProtectedRoute path="/dashboard" component={Dashboard} />
<Route exact path="/" component={Home} />
</Switch>
</Router>
);
}
export default App;
使用Redux来管理用户的认证状态。
// actions.js
export const login = () => ({
type: 'LOGIN',
});
export const logout = () => ({
type: 'LOGOUT',
});
// reducer.js
const initialState = {
isAuthenticated: false,
};
const authReducer = (state = initialState, action) => {
switch (action.type) {
case 'LOGIN':
return { ...state, isAuthenticated: true };
case 'LOGOUT':
return { ...state, isAuthenticated: false };
default:
return state;
}
};
export default authReducer;
创建一个ProtectedRoute
组件,用于检查用户的认证状态。
import React from 'react';
import { Route, Redirect } from 'react-router-dom';
import { useSelector } from 'react-redux';
function ProtectedRoute({ component: Component, ...rest }) {
const isAuthenticated = useSelector(state => state.auth.isAuthenticated);
return (
<Route
{...rest}
render={props =>
isAuthenticated ? (
<Component {...props} />
) : (
<Redirect to="/login" />
)
}
/>
);
}
export default ProtectedRoute;
ProtectedRoute
组件正确处理了认证状态的检查和重定向逻辑。React.memo
或useMemo
来优化性能。完整的示例代码可以在以下GitHub仓库中找到:

通过以上步骤,你可以在React Redux应用中实现受保护的路由。希望这些信息对你有所帮助!
