[chentianyuan]

router.js

import Nerv from 'nervjs'
import {HashRouter as Router, Route, Switch} from 'react-router-dom'
import Home from './container/Home/home'
import Login from './container/Login/login'

const coverRoute = () => {
    return (
        <Router>
            <Switch mode=" hashHistory">
                <Route exact path="/" component={Login}></Route>
                <Route exact path="/login" component={Login}></Route>
                <Route exact path="/home" component={Home}></Route>
            </Switch>
        </Router>
    )
}

export default coverRoute
