react-router 与react-reduct 配合使用时，页面不刷新问题

参考文档：https://reacttraining.com/react-router/core/guides/redux-integration/blocked-updates

异常现象点击Link url 变化但是页面不更新
出现此问题的条件：
1.使用了react-reduct 的connect
2.Router与Root 之间有 有layout布局 元素
解决办法：withRouter 包裹组件
原因：react-reduct shouldComponentUpdate 没有接收到任何属性改变，因此不再重新绘制页面

var Home =  withRouter (connect()(() => "Cal"}>Home 点击到子页面
))
var Cal = withRouter( connect()(() => 
Cal "/Home"}>回到首页
))
var Layout =withRouter ( connect()((props) => 
头{props.children}尾
))

异常代码如下

import React from 'react'
import ReactDOM from 'react-dom'
import {createStore} from 'redux'
import {Provider, connect} from 'react-redux'
import {Route, Switch, Link, BrowserRouter as Router} from 'react-router-dom' ;
const store = createStore(
    function* (state, action) {
        return state
    }
)
var Home = connect()(() => "Cal"}>Home 点击到子页面
)
var Cal = connect()(() => 
Cal "/Home"}>回到首页
)
var Layout = connect()((props) => 
头{props.children}尾
)
ReactDOM.render(
    
        
            

                
                    
                        "/Home" component={Home}/>
                        "/Cal" component={Cal}/>
                    
                
            
        
    ,
    document.getElementById('root')
)
