使用react路由器v4 / v5嵌套路由

我目前正在努力使用react路由器v4嵌套路由。

中的路由配置是最接近的例子 React-Router v4文档。

我想把我的应用程序分成2个不同的部分。

一个前台和一个管理区域。

我在想这样的事情:

<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} />

前端的布局和风格与管理区域不同。在frontpage中，home, about，还有一个应该是子路由。

/home应该呈现在Frontpage组件中，/admin/home应该呈现在Backend组件中。

我尝试了一些其他的变化，但我总是以不点击/home或/admin/home结束。

最终解决方案:

这是我现在使用的最终解决方案。这个例子还有一个全局错误组件，就像传统的404页面一样。

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;

一个完整的React路由器v6或版本6的答案，以防万一。

import Dashboard from "./dashboard/Dashboard";
import DashboardDefaultContent from "./dashboard/dashboard-default-content";
import { Route, Routes } from "react-router";
import { useRoutes } from "react-router-dom";

/*Routes is used to be Switch*/
const Router = () => {

  return (
    <Routes>
      <Route path="/" element={<LandingPage />} />
      <Route path="games" element={<Games />} />
      <Route path="game-details/:id" element={<GameDetails />} />
      <Route path="dashboard" element={<Dashboard />}>
        <Route path="/" element={<DashboardDefaultContent />} />
        <Route path="inbox" element={<Inbox />} />
        <Route path="settings-and-privacy" element={<SettingsAndPrivacy />} />
        <Route path="*" element={<NotFound />} />
      </Route>
      <Route path="*" element={<NotFound />} />
    </Routes>
  );
};
export default Router;

import DashboardSidebarNavigation from "./dashboard-sidebar-navigation";
import { Grid } from "@material-ui/core";
import { Outlet } from "react-router";

const Dashboard = () => {
  return (
    <Grid
      container
      direction="row"
      justify="flex-start"
      alignItems="flex-start"
    >
      <DashboardSidebarNavigation />
      <Outlet />
    </Grid>
  );
};

export default Dashboard;

其他回答

在react-router-v4中，不嵌套<Routes />。相反，将它们放在另一个<Component />中。

例如

<Route path='/topics' component={Topics}>
  <Route path='/topics/:topicId' component={Topic} />
</Route>

应该成为

<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>
)

下面是一个直接来自react-router文档的基本示例。

我更喜欢使用react函数。这个解决方案很简短，可读性更强

const MainAppRoutes = () => (
    <Switch>
        <Route exact path='/' component={HomePage} />
        {AdminRoute()}                  
        {SampleRoute("/sample_admin")}  
    </Switch>
);

/*first implementation: without params*/
const AdminRoute = () => ([
    <Route path='/admin/home' component={AdminHome} />,
    <Route path='/admin/about' component={AdminAbout} />
]);

/*second implementation: with params*/
const SampleRoute = (main) => ([
    <Route path={`${main}`} component={MainPage} />,
    <Route path={`${main}/:id`} component={MainPage} />
]);

你可以试试 Routes.js

import React, { Component } from 'react'
import { BrowserRouter as Router, Route } from 'react-router-dom';
import FrontPage from './FrontPage';
import Dashboard from './Dashboard';
import AboutPage from './AboutPage';
import Backend from './Backend';
import Homepage from './Homepage';
import UserPage from './UserPage';
class Routes extends Component {
    render() {
        return (
            <div>
                <Route exact path="/" component={FrontPage} />
                <Route exact path="/home" component={Homepage} />
                <Route exact path="/about" component={AboutPage} />
                <Route exact path="/admin" component={Backend} />
                <Route exact path="/admin/home" component={Dashboard} />
                <Route exact path="/users" component={UserPage} />    
            </div>
        )
    }
}

export default Routes

App.js

import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
import { BrowserRouter as Router, Route } from 'react-router-dom'
import Routes from './Routes';

class App extends Component {
  render() {
    return (
      <div className="App">
      <Router>
        <Routes/>
      </Router>
      </div>
    );
  }
}

export default App;

我认为你在这里也可以达到同样的效果。

React路由器v6

允许使用嵌套路由(如v3)和分离的、分离的路由(v4, v5)。

嵌套的路线

对于小/中型应用，将所有路由放在一个地方:

<Routes>
  <Route path="/" element={<Home />} >
    <Route path="user" element={<User />} /> 
    <Route path="dash" element={<Dashboard />} /> 
  </Route>
</Routes>

替代方案:通过useRoutes将路由定义为纯JavaScript对象。

单独的通道

你可以使用分离路由来满足大型应用程序的需求，比如代码拆分:

// inside App.jsx:
<Routes>
  <Route path="/*" element={<Home />} />
</Routes>

// inside Home.jsx:
<Routes>
  <Route path="user" element={<User />} />
  <Route path="dash" element={<Dashboard />} />
</Routes>
