当我使用 react-router-dom 中的 BrowserRouter 时，我的路由可以正常工作。但为了使用自定义历史记录，我将 BrowserRouter 替换为 react-router 中的 Router。之后，我的路由组件无法正确加载，但网址可以正确更改。 这是我的代码：

AppRouter-JS：----

import React from 'react';
import { Router, Route, Switch} from 'react-router';
// import { BrowserRouter as Router,Route, Switch} from 'react-router-dom';
import {createBrowserHistory} from 'history'

import Header from '../components/Header.js';
import Dashboard from '../components/DashboardPage.js'
import CreateExpense from '../components/CreateExpensePage.js';
import EditExpense from '../components/EditExpensePage.js';
import Help from '../components/HelpPage.js';
import PageNotFound from '../components/PageNotFound.js'
import LoginPage from '../components/LoginPage.js'


export const history = createBrowserHistory();

  const AppRouter = ()=>(
    <Router history={history}>
    <div>
      <Header/>
      <Switch>
        <Route path='/' exact={true} component={LoginPage}/>
        <Route path='/dashboard' component={Dashboard}/>
        <Route path='/create' component={CreateExpense} />
        <Route path="/edit/:id" component={EditExpense}/>
        <Route path='/help' component={Help} />
        <Route component={PageNotFound}/>
      </Switch>
    </div>
  </Router>
  )
  export default AppRouter;

HeaderJS：--（这里我们有 NavLinks）

import React from 'react';
import {NavLink, Link} from 'react-router-dom';
import {connect} from 'react-redux';

import {LogoutAction} from '../Redux/Actions/AuthActions.js'

export const Header = ({logoutAction})=>(
    <header>
      <h1>Expense Tracker</h1>
      <p><NavLink exact activeClassName='active-class' to='/'>Home Page</NavLink></p>
      <p><NavLink activeClassName='active-class' to='/create'>Add Expense</NavLink></p>
      <p><NavLink activeClassName='active-class' to='/help'>Help Page</NavLink></p>
      <button onClick={logoutAction}>Logout</button>
    </header>
);

const mapDispatchToProps = (dispatch)=> {
  return {
    logoutAction: ()=> dispatch(LogoutAction())
  }
}

  export default connect(undefined,mapDispatchToProps) (Header);

单击任何 NavLink 或 Link 后，它始终会打开 PageNotFound 组件。
