리액트 라우터 v4/v5를 사용한 네스트 루트
현재 리액트 라우터 v4를 사용하여 루트를 네스트하는 데 어려움을 겪고 있습니다.
가장 가까운 예는 React-Router v4 매뉴얼의 루트 설정입니다.
앱을 두 부분으로 나누고 싶습니다.
프런트 엔드 및 관리 영역.
난 이런 생각을 하고 있었어
<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} />
프런트 엔드의 레이아웃과 스타일이 관리 영역과 다릅니다.그래서 집으로 가는 1면에는, 대략, 그리고 그 중 하나가 어린이용 경로일 것입니다.
/home
와 론론 and and and and and and and and and and and and and and and and and and and and and and로 렌더링해야 합니다./admin/home
백엔드 컴포넌트 내에서 렌더링해야 합니다.
안 요./home
★★★★★★★★★★★★★★★★★」/admin/home
.
최종 솔루션:
이것이 제가 현재 사용하고 있는 최종 해결책입니다.이 예에서는 기존 404 페이지와 같은 글로벌 오류 구성 요소도 있습니다.
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;
react-router-v4를 내포하지 .<Routes />
다른 another, 른, 른, 른, another, another, , another, another, another, another, another, another, another, another, another, another, another에 넣습니다.<Component />
.
예를 들어.
<Route path='/topics' component={Topics}>
<Route path='/topics/:topicId' component={Topic} />
</Route>
가 되어야 한다
<Route path='/topics' component={Topics} />
와 함께
const Topics = ({ match }) => (
<div>
<h2>Topics</h2>
<Link to={`${match.url}/exampleTopicId`}>
Example topic
</Link>
<Route path={`${match.path}/:topicId`} component={Topic}/>
</div>
)
다음은 리액트 라우터의 매뉴얼에서 직접 인용한 기본적인 예입니다.
react-router v6
2022년 업데이트 - v6이 중첩되었습니다.Route
제제로 작작작작 ™
이 질문은 v4/v5에 관한 것입니다만, 가능한 한 v6를 사용해 주세요.
이 블로그 투고의 코드 예를 참조해 주세요.그러나 아직 업그레이드할 수 없는 경우...
react-router v4 & v5
루트를 중첩하려면 루트의 하위 구성요소에 루트를 배치해야 합니다.
단, 컴포넌트 간에 루트를 분할하는 것보다 인라인 구문을 사용하는 것이 좋으면 에 기능 컴포넌트를 제공할 수 있습니다.render
당신이 둥지를 틀고자 하는 길의 지주.
<BrowserRouter>
<Route path="/" component={Frontpage} exact />
<Route path="/home" component={HomePage} />
<Route path="/about" component={AboutPage} />
<Route
path="/admin"
render={({ match: { url } }) => (
<>
<Route path={`${url}/`} component={Backend} exact />
<Route path={`${url}/home`} component={Dashboard} />
<Route path={`${url}/users`} component={UserPage} />
</>
)}
/>
</BrowserRouter>
render
해야지, 받침대를는 안 된다.component
모든 렌더링에 인라인 기능 컴포넌트가 다시 마운트되지 않도록 하기 때문입니다.상세한 것에 대하여는, 메뉴얼을 참조해 주세요.
이 예에서는 네스트된 루트를 fragment로 랩하고 있습니다.React 16 이전 버전에서는<div>
★★★★★★ 。
리액션 라우터 v4가 이 질문이 게시된 후 급격히 변화했다는 점을 언급하고 싶습니다.
<Match>
★★★★★★★★★★★★★★★★★★!<Switch>
첫 번째 일치만 렌더링합니다. <Redirect>
그냥..이랬다 exact
부분 일치를 포함하거나 제외한다.
문서를 참조해 주세요.그들은 훌륭하다.https://reacttraining.com/react-router/
여기 당신의 질문에 대답하는데 도움이 되었으면 하는 예가 있습니다.
<Router>
<div>
<Redirect exact from='/' to='/front'/>
<Route path="/" render={() => {
return (
<div>
<h2>Home menu</h2>
<Link to="/front">front</Link>
<Link to="/back">back</Link>
</div>
);
}} />
<Route path="/front" render={() => {
return (
<div>
<h2>front menu</h2>
<Link to="/front/help">help</Link>
<Link to="/front/about">about</Link>
</div>
);
}} />
<Route exact path="/front/help" render={() => {
return <h2>front help</h2>;
}} />
<Route exact path="/front/about" render={() => {
return <h2>front about</h2>;
}} />
<Route path="/back" render={() => {
return (
<div>
<h2>back menu</h2>
<Link to="/back/help">help</Link>
<Link to="/back/about">about</Link>
</div>

return <h2>back help</h2>;
}} />
<Route exact path="/back/about" render={() => {
return <h2>back about</h2>;
}} />
</div>

네스트된 루트를 정의하는 데 성공했습니다.Switch
루트 루트보다 먼저 네스트된 루트를 정의합니다.
<BrowserRouter>
<Switch>
<Route path="/staffs/:id/edit" component={StaffEdit} />
<Route path="/staffs/:id" component={StaffShow} />
<Route path="/staffs" component={StaffIndex} />
</Switch>
</BrowserRouter>

다른 방법:루트를 를 통해 플레인 JavaScript 개체로 정의합니다.
