我尝试嵌套一个路由：我在 Catalog 组件中有一个产品目录，该目录与 URL “backoffice/catalog” 匹配。

如果 URL 与 “backoffice/catalog/edit” 匹配，我想路由到 Edition 组件，但我需要 Edition 组件作为 Catalog 的子组件来共享道具。

我真的不明白为什么嵌套路由不起作用，请救救我！如果我的应用程序有任何问题，请随时告诉我，我很了解 JavaScript，但我从 React 开始。

这是我的应用程序组件：

import React from "react";
import { Route, Switch } from "react-router-dom";
import { Home } from "./components/Static/Home.js";
import { Dashboard } from "./components/Backoffice/Dashboard.js";
import { Catalog } from "./components/Backoffice/catalog/Catalog.js";
import { Login } from "./components/Login/Login.js";
import { Signup } from "./components/Signup/Signup.js";
import { PrivateRoute } from "./components/PrivateRoute.js";
import "./scss/App.scss";
import {Header} from "./components/Structure/Header";
import {BOHeader} from "./components/Structure/Backoffice/Header";
import {List} from "./components/Listing/List";

function App()
{
  return (
    <div className="App">
      <div className="App-content">
          <Switch>
              <Route path='/backoffice' component={BOHeader} />
              <Route path='/' component={Header} />
          </Switch>
          <Switch>
              <Route exact path='/' component={Home} />
              <Route exact path='/login' component={Login} />
              <Route exact path='/signup' component={Signup} />
              <Route path='/listing' component={List}/>
              <PrivateRoute exact path='/backoffice' component={Dashboard}/>
              <PrivateRoute exact path='/backoffice/catalog' component={Catalog}/>
          </Switch>
      </div>
    </div>
  );
}

export default App;

这是我的目录组件（路由是在渲染方法中制作的：

import React from 'react';
import Data from '../../../Utils/Data';
import {Product} from './Product';
import {Edition} from './Edition';
import {
    BrowserRouter as Router,
    Switch,
    Route,
    Link,
    useRouteMatch,
    useParams
} from "react-router-dom";

export class Catalog extends React.Component
{
    state = {
        title: '',
        products: [],
        editionProduct: null
    };

    obtainProducts = () =>
    {
        Data.products.obtain()
            .then(products => {this.setState({products: products});})
    };

    editProductHandler = product =>
    {
        this.setState({editionProduct: product});
    };

    saveProductHandler = product =>
    {
        Data.products.save(product).then(() => {
            this.state.products.map(item => {
                item = item._id === product._id ? product : item;
                return item;
            })
        });
    };

    deleteProductHandler = event =>
    {
        const productId = event.target.closest('.product-actions').dataset.productid;
        let products = this.state.products.filter(product => {
            return product._id !== productId;
        });
        this.setState({products: products}, () => {
            Data.products.remove(productId);
        });
    };

    displayProducts = () =>
    {
        return this.state.products.map(product => {
           return (
                <li key={product._id} className='catalog-item'>
                   <Product
                       deleteProductHandler={this.deleteProductHandler}
                       editProductHandler={this.editProductHandler}
                       data={product}
                   />
               </li>
            )
        });
    };


    componentWillMount()
    {
        this.obtainProducts();
    }

    render() {
        const Products = this.displayProducts();
        let { path, url } = useRouteMatch();
        return (
            <div className={this.state.editionProduct ? 'catalog edit' : 'catalog'}>
                <h1>Catalog</h1>
                <Switch>
                    <Route exact path={path}>
                        <ul className='catalog-list'>{Products}</ul>
                    </Route>
                    <Route path={`${path}/edit`}>
                        <Edition saveProductHandler={this.saveProductHandler} product={this.state.editionProduct} />
                    </Route>
                </Switch>
            </div>
        );
    }
}

有什么想法吗？
