5-9 多级路由跳转不正确
问题描述：我在Routes.js里把 '/'路由的exact属性注释后，感觉所以 / 一下的都会走Home，/ttt的Login则不会渲染，而且点击Login的Link后，也会把Home一起渲染。
我检测了client和server端的代码，都没找到问题，而且我也对比了老师5-8，5-9，5-10的代码也没发现什么，视频也重复看了几遍，还是不行。请老师帮忙解答一下
client/index.js
import React from 'react'
import ReactDOM from 'react-dom'
import { BrowserRouter, Route } from 'react-router-dom'
import routes from '../Routes'
import { Provider } from 'react-redux'
import getStore from '../store'
const App = () => {
return (
<Provider store={getStore()}>
<BrowserRouter>
<div>
{routes.map((route) => <Route {...route} />)}
</div>
</BrowserRouter>
</Provider>
)
}
ReactDOM.hydrate(<App />, document.getElementById('root'));
server/index.js
import express from 'express'
import { render} from './util'
const app = express();
app.use(express.static('public'))
app.get('*', function (req, res) {
res.send(render(req));
});
const server = app.listen(3000);
server/util.js
import React from 'react'
import { renderToString } from 'react-dom/server'
import { StaticRouter, Route, matchPath } from 'react-router-dom'
// import { matchRoutes } from 'react-router-config'
import routes from '../Routes'
import { Provider } from 'react-redux'
import getStore from '../store'
export const render = (req) => {
const store = getStore()
// const matchedRoutes = matchRoutes(routes, req.path)
const matchRoutes = []
// 根据路由的路径，来往store里面加数据
routes.some(route => {
const match = matchPath(req.path, route)
if (match) {
matchRoutes.push(route)
}
})
console.log(matchRoutes)
const content = renderToString(
<Provider store={store}>
<StaticRouter context={{}} location={req.path}>
<div>
// 这里的matchRoutes，我也改成routes，效果一样
{matchRoutes.map((route) => (<Route {...route} />))}
</div>
</StaticRouter>
</Provider>
);
return (
`
<html>
<head>
<title>ss</title>
</head>
<body>
<div id="root">${content}</div>
<script src='/index.js'></script>
</body>
</html>
`
)
}
Routes.js
import Home from './containers/Home'
import Login from './containers/Login'
export default [
{
path: '/',
component: Home,
// exact: true,
loadData: Home.loadData,
key: 'home',
routes: [
{
path: '/ttt',
component: Login,
exact: true,
key: 'ttt',
},
],
},
{
path: '/login',
component: Login,
exact: true,
key: 'login',
},
]
