在尝试执行嵌套路由时,当路由通过Link或history.push更改时,我无法装入子组件;但如果直接在root.js文件中声明路由,它就可以工作。所以,理想情况下我想在root / routes.js文件中保留尽可能多的路由配置,而不是整个App(我正在迭代root / routes.js对象而不是自动执行此操作;我的意思是......尝试)
To break it down logically (it's a bit abstract, but check the code below afterwards please):
- There's a `root/routes.js` that has all the routes configuration (parents, nested components, etc)
- The `root.js` defines the `<Route...>` where the attribute `component` is the return value of a function that passes the `routes` configuration to its `routes` component prop
- the main wrapper iterates over the component prop `routes` and defines `child` routes automatically...I mean...I'm trying...
为什么我要这样做?我的大脑工作的方式,为什么不工作?反应路由器4之前是可能的
<MyAppWrapper>
<CommonNavigationBar />
<Main>
----- dynamic / changes by route etc -----
</Main>
<Footer />
</MyAppWrapper>
我想知道我的尝试失败了吗?
// Working version
import React from 'react'
import { Route } from 'react-router'
import { BrowserRouter } from 'react-router-dom'
import { Provider } from 'react-redux'
import rootRoutes from './routes'
import App from '../app/containers/app'
const Root = ({store, history}) => {
return (
<Provider store={store}>
<BrowserRouter history={history}>
<Route path='/' component={App} />
</BrowserRouter>
</Provider>
)
}
export default Root
对于前面的示例,App组件是嵌套的,下面我正在尝试动态地执行此操作...并且由于某种原因它失败了!虽然它应该完全相同......某处必须有一个错字...
等
import React, { Component } from 'react'
import { isBrowser } from 'reactatouille'
import { connect } from 'react-redux'
import { bindActionCreators } from 'redux'
import { withRouter, Route } from 'react-router'
import Navbar from '../navbar'
import JourneySelector from '../journeySelector'
import reservationFinder from '../../../reservationFinder'
// include the stylesheet entry-point
isBrowser() && require('../../../../sass/app.scss')
class App extends Component {
constructor (props) {
super(props)
this.state = {
init: true
}
}
render () {
return (
<div className={'app' + ' ' + (!this.state.init && 'uninitialised')}>
<Navbar />
<main>
<Route exact path='/' component={JourneySelector} />
<Route exact path='/reservation-finder' component={reservationFinder.containers.App} />
</main>
</div>
)
}
}
// export default App
function mapStateToProps (state, ownProps) {
return {
// example: state.example
}
}
function matchDispatchToProps (dispatch) {
return bindActionCreators({
// replay: replay
}, dispatch)
}
export default connect(mapStateToProps, matchDispatchToProps)(withRouter(App))
虽然我的技术失败了(我所要做的就是迭代root / routes子路由来生成这些):
// root/routes.js
import app from '../app'
import reservationFinder from '../reservationFinder'
const rootRoutes = [
{
path: '/',
component: app.containers.App,
exact: true,
routes: [{
path: '/',
exact: true,
component: app.containers.JourneySelector
}, {
path: '/reservation-finder',
component: reservationFinder.containers.App
}]
}
]
export default rootRoutes
根js文件。您看到setRoute
fn返回一个新组件,其中子路由作为props
传递?我相信这会奏效:
// root.js
import React from 'react'
import { Route, Switch } from 'react-router'
import { BrowserRouter } from 'react-router-dom'
import { Provider } from 'react-redux'
import rootRoutes from './routes'
const setRoute = (route) => {
const MyComponent = route.component
return <Route key={route.path} exact={route.exact || false} component={() => (<MyComponent routes={route.routes} />)} />
}
const Root = ({store, history}) => {
return (
<Provider store={store}>
<BrowserRouter history={history}>
{ rootRoutes.map(route => setRoute(route)) }
</BrowserRouter>
</Provider>
)
}
export default Root
我想用作包装器的主应用程序:
// main app
import React, { Component } from 'react'
import { isBrowser } from 'reactatouille'
import { connect } from 'react-redux'
import { bindActionCreators } from 'redux'
import { withRouter, Route } from 'react-router'
import Navbar from '../navbar'
// include the stylesheet entry-point
isBrowser() && require('../../../../sass/app.scss')
class App extends Component {
constructor (props) {
super(props)
this.state = {
init: true
}
}
render () {
return (
<div className={'app' + ' ' + (!this.state.init && 'uninitialised')}>
<Navbar />
<main>
{ Array.isArray(this.props.routes) && this.props.routes.map(route => <Route key={route.path} {...route} />) }
</main>
</div>
)
}
}
// export default App
function mapStateToProps (state, ownProps) {
return {
// example: state.example
}
}
function matchDispatchToProps (dispatch) {
return bindActionCreators({
// replay: replay
}, dispatch)
}
export default connect(mapStateToProps, matchDispatchToProps)(withRouter(App))
我明白我可能会有类似的东西,比如?!
// root
import React from 'react'
import { Route, Switch } from 'react-router'
import { BrowserRouter } from 'react-router-dom'
import { Provider } from 'react-redux'
import rootRoutes from './routes'
import MyAppWrapper from 'xxx/MyAppWrapper'
const setRoute = (route) => {
const MyComponent = route.component
return <Route key={route.path} exact={route.exact || false} component={() => (<MyComponent routes={route.routes} />)} />
}
const Root = ({store, history}) => {
return (
<Provider store={store}>
<BrowserRouter history={history}>
<MyAppWrapper>
<Route path='x' component={x} />
<Route path='y' component={y} />
</MyAppWrapper>
</BrowserRouter>
</Provider>
)
}
export default Root
注意:在测试期间,我注意到它在服务器端工作?我的意思是,我可能错过了一些东西,而且我没有保存我的工作。此外,失败时,前一个组件(默认)仍然已安装且未卸载
我甚至尝试过(没有成功......我想知道这是不是一个错误):
import React from 'react'
import { Route } from 'react-router'
import { BrowserRouter } from 'react-router-dom'
import { Provider } from 'react-redux'
import App from '../app/containers/app'
import rootRoutes from './routes'
const Root = ({store, history}) => {
return (
<Provider store={store}>
<BrowserRouter history={history}>
<Route path='/' render={() => (
<App />
)} />
</BrowserRouter>
</Provider>
)
}
export default Root
好的,我认为这是一个如此报告的错误(https://github.com/ReactTraining/react-router/issues/5190),您可以在此处找到实时示例(https://codepen.io/helderoliveira/pen/rmXdgd),点击topic
。也许我正在尝试做的事情不受支持,但我们应该收到错误消息而不是空白。

好的,我发现了错字。解决方案是使用render并通过Object.assign和spread运算符传递routerProps +你想要的任何其他道具!
// root.js
import React from 'react'
import { Route } from 'react-router'
import { BrowserRouter } from 'react-router-dom'
import { Provider } from 'react-redux'
import App from '../app/containers/app'
import rootRoutes from './routes'
const Root = ({store, history}) => {
return (
<Provider store={store}>
<BrowserRouter history={history}>
<Route path='/' render={routeProps => <App {...Object.assign({}, routeProps, { routes: rootRoutes[0].routes })} />} />
</BrowserRouter>
</Provider>
)
}
export default Root
主app包装器:
class App extends Component {
render () {
return (
<div className={'app kiosk' + ' ' + (!this.state.init && 'uninitialised')}>
<Navbar />
<main>
{ Array.isArray(this.props.routes) && this.props.routes.map(route => <Route key={route.path} exact={route.exact} path={route.path} component={route.component} />) }
</main>
</div>
)
}
}
export default App

const MyComponent = route.component
return <Route key={route.path} path={route.path} render={routeProps => <MyComponent {...Object.assign({}, routeProps, { routes: rootRoutes[0].routes })} />} />
