這是router.jsx

import React from 'react'
import { Router, Route, Link, Switch, Redirect} from 'react-router-dom';
import history from '../history/history'

import Login from '../views/login'
import Another from '../views/another'

const Routes = (
  <Router history={history}>
    <Switch>
      <Route path="/" component={Login}></Route>
      <Route path="/another" component={Another}></Route>      
    </Switch>
  </Router>
)

export default Routes

默認(rèn)是可以渲染Login組件的

但是手動(dòng)改了路由之后頁面還是原來的Login組件
