带有反应路由器 v4/v5 的嵌套路由 [英] Nested routes with react router v4 / v5

问题描述

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.

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.

<小时>

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="https://reacttraining.com/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.
