1、封装一个AuthRouter

import React from 'react';
import { Route, Redirect } from 'react-router-dom';

 const DATA = {
    user: Storage.getStore('user')
   
} 



const AuthRouter = (props) => {
    const { component: Component, needLogin } = props;
    if (needLogin == false || logined()) {
        return (<Route key={props.location.pathname} {...props} component={Component} />);
    } else {
        return <Redirect exact {...props} from={props.path} to={'/login'} />
    }
}

const logined = () => {
    return DATA.user != null
}

const Login = (user) => {
    DATA.user = user;
    Storage.setStore("user", user)
}

const Loginout = () => {
    DATA.user = null
    Storage.removeStore('user')
}

const getUser = () => {

    return DATA.user || {};

}

export { getUser, AuthRouter, Login, Loginout }

2、使用

 <HashRouter>
      <Suspense fallback={<PageLoading />}>
        <Switch>
          <AuthRouter exact needLogin={false} path="/login" component={withTracker(Login)} />
          <AuthRouter exact path="/work/:type/:cid" component={withTracker(Work)} />
          <AuthRouter  path="/" component={withTracker(Index)} />
        </Switch>
      </Suspense>
    </HashRouter>
