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{
//此时才能获取this.props,包含(history, match, location)三个对象
console.log(this.props); //输出{match: {…}, location: {…}, history: {…}, 等}
render(){return (<div className=‘app‘>
<NavLink to=‘/one/users‘>用户列表</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); //这里要执行一下WithRouter
