demo:
import React,{Component} from 'react' import {Switch,Route,NavLink,Redirect,withRouter} from 'react-router-dom' //引入withRouter import One from './One' import NotFound from './NotFound' class App extends Component{ //此時才能獲取this.props,包含(history, match, location)三個物件 console.log(this.props); //輸出{match: {…}, location: {…}, history: {…}, 等} render(){return (<div className='app'> <NavLink to='/one/users'>使用者列表</NavLink> <NavLink to='/one/companies'>公司列表</NavLink> <Switch> <Route path='/one/:type?' component={One} /> <Redirect from='/' to='/one' exact /> <Route component={NotFound} /> </Switch> </div>) } } export default withRouter(App); //這裡要執行一下WithRouter
