我目前正在努力使用 react router v4 嵌套路由.
最接近的例子是路由配置中的React-Router v4 文档.
我想将我的应用分成 2 个不同的部分.
前端和管理区域.
我正在考虑这样的事情:
<Match pattern="/home" component={HomePage}/><Match pattern="/about" component={AboutPage}/></匹配><Match pattern="/admin" component={Backend}><Match pattern="/home" component={Dashboard}/><Match pattern="/users" component={UserPage}/></匹配><Miss component={NotFoundPage}/>前端的布局和样式与管理区域不同.所以在首页的路线回家,大约等一个应该是子路线.
/home 应该呈现在 Frontpage 组件中,而 /admin/home 应该呈现在后端组件中.
我尝试了一些变体,但最终我总是没有点击/home 或/admin/home.

因为这个帖子现在有很多观点,所以我用最终的解决方案更新了它.我希望它可以帮助某人.

最终解决方案:
这是我现在使用的最终解决方案.这个例子也有一个像传统 404 页面一样的全局错误组件.
import React, { Component } from 'react';从'react-router-dom'导入{开关,路由,重定向,链接};const Home = () =><div><h1>首页</h1></div>;const 用户 = () =><div><h1>用户</h1></div>;const 错误 = () =><div><h1>错误</h1></div>const 前端 = 道具 =>{console.log('前端');返回 (<div><h2>前端</h2><p><Link to="/">Root</Link></p><p><Link to="/user">User</Link></p><p><Link to="/admin">后端</Link></p><p><Link to="/the-route-is-swiggity-swoute">Swiggity swooty</Link></p><开关><路由精确路径='/' component={Home}/><Route path='/user' component={User}/><重定向到={{状态:{错误:真实}}}/></开关><footer>底部</footer>);}const 后端 = 道具 =>{console.log('后端');返回 (<div><h2>后端</h2><p><Link to="/admin">Root</Link></p><p><Link to="/admin/user">用户</Link></p><p><Link to="/">前端</Link></p><p><Link to="/admin/the-route-is-swiggity-swoute">Swiggity swooty</Link></p><开关><路由精确路径='/admin' component={Home}/><Route path='/admin/user' component={User}/><重定向到={{状态:{错误:真实}}}/></开关><footer>底部</footer>
);}类 GlobalErrorSwitch 扩展组件 {previousLocation = this.props.locationcomponentWillUpdate(nextProps) {const { location } = this.props;if (nextProps.history.action !== 'POP'&&(!location.state || !location.state.error)) {this.previousLocation = this.props.location};}使成为() {const { location } = this.props;const isError = !!(location.state &&location.state.error &&this.previousLocation !== location//不是初始渲染)返回 (<div>{错误?<路由组件={Error}/>: <开关位置={isError ?this.previousLocation:位置}><Route path="/admin" component={Backend}/><Route path="/" component={Frontend}/></开关>}
)}}类 App 扩展组件 {使成为() {return <Route component={GlobalErrorSwitch}/>}}导出默认应用程序;
解决方案在 react-router-v4 中,您不需要嵌套 .相反,您将它们放在另一个 中.
例如
<Route path='/topics/:topicId' component={Topic}/></路线>应该变成
与
const 主题 = ({ match }) =>(<div><h2>主题</h2><链接到={`${match.url}/exampleTopicId`}>示例主题</链接><路由路径={`${match.path}/:topicId`} component={Topic}/>)
这是一个直接来自 react-router 基本示例="reacttraining/react-router/web/guides/quick-start" rel="noreferrer">文档.
I am currently struggling with nesting routes using react router v4.
The closest example was the route config in the React-Router v4 Documentation.
I want to split my app in 2 different parts.
A frontend and an admin area.
I was thinking about something like this:
<Match pattern="/" component={Frontpage}> <Match pattern="/home" component={HomePage} /> <Match pattern="/about" component={AboutPage} /> </Match> <Match pattern="/admin" component={Backend}> <Match pattern="/home" component={Dashboard} /> <Match pattern="/users" component={UserPage} /> </Match> <Miss component={NotFoundPage} />The frontend has a different layout and style than the admin area. So within the frontpage the route home, about and so one should be the child routes.
/home should be rendered into the Frontpage component and /admin/home should be rendered within the Backend component.
I tried some variations but I always ended in not hitting /home or /admin/home.

Because this post has a lot of views right now I updated it with the final solution. I hope it helps someone.

Final solution:
This is the final solution I am using right now. This example also has a global error component like a traditional 404 page.
import React, { Component } from 'react'; import { Switch, Route, Redirect, Link } from 'react-router-dom'; const Home = () => <div><h1>Home</h1></div>; const User = () => <div><h1>User</h1></div>; const Error = () => <div><h1>Error</h1></div> const Frontend = props => { console.log('Frontend'); return ( <div> <h2>Frontend</h2> <p><Link to="/">Root</Link></p> <p><Link to="/user">User</Link></p> <p><Link to="/admin">Backend</Link></p> <p><Link to="/the-route-is-swiggity-swoute">Swiggity swooty</Link></p> <Switch> <Route exact path='/' component={Home}/> <Route path='/user' component={User}/> <Redirect to={{ state: { error: true } }} /> </Switch> <footer>Bottom</footer> </div> ); } const Backend = props => { console.log('Backend'); return ( <div> <h2>Backend</h2> <p><Link to="/admin">Root</Link></p> <p><Link to="/admin/user">User</Link></p> <p><Link to="/">Frontend</Link></p> <p><Link to="/admin/the-route-is-swiggity-swoute">Swiggity swooty</Link></p> <Switch> <Route exact path='/admin' component={Home}/> <Route path='/admin/user' component={User}/> <Redirect to={{ state: { error: true } }} /> </Switch> <footer>Bottom</footer> </div> ); } class GlobalErrorSwitch extends Component { previousLocation = this.props.location componentWillUpdate(nextProps) { const { location } = this.props; if (nextProps.history.action !== 'POP' && (!location.state || !location.state.error)) { this.previousLocation = this.props.location }; } render() { const { location } = this.props; const isError = !!( location.state && location.state.error && this.previousLocation !== location // not initial render ) return ( <div> { isError ? <Route component={Error} /> : <Switch location={isError ? this.previousLocation : location}> <Route path="/admin" component={Backend} /> <Route path="/" component={Frontend} /> </Switch>} </div> ) } } class App extends Component { render() { return <Route component={GlobalErrorSwitch} /> } } export default App;解决方案
In react-router-v4 you don't nest <Routes />. Instead, you put them inside another <Component />.
For instance
<Route path='/topics' component={Topics}> <Route path='/topics/:topicId' component={Topic} /> </Route>should become
<Route path='/topics' component={Topics} />with
const Topics = ({ match }) => ( <div> <h2>Topics</h2> <Link to={`${match.url}/exampleTopicId`}> Example topic </Link> <Route path={`${match.path}/:topicId`} component={Topic}/> </div> )
Here is a basic example straight from the react-router documentation.
