React 中的嵌套路由不呈现嵌套组件

Question

嵌套路由不起作用。 'Landing' 和 'home' 组件正确显示但嵌套组件未呈现。

布局组件直接导入app.js 控制台中没有错误，但 'Feed' 和 'Myprofile' 等嵌套组件未呈现。

查看代码

import React from 'react';
import { Route, Switch, BrowserRouter as Router} from 'react-router-dom';
import Sidebar from '../componants/Sidebar'
import Navbar from '../componants/Navbar';
import PathRouter from '../Routers/PathRouters'
import Landing from '../pages/Landing';

const Home=()=>{
    
    return(
        <>
            <div className="container-fluid">
                <Navbar />

                <div className="rows row">
                    <div className='col-3'>
                        <Sidebar />
                    </div>
                    <div className="col-9 ">
                        <div className="content">                            
                            <Switch>
                                {PathRouter.map((prop, key) => {
                                    return (
                                        <Route
                                           exact path={prop.path}
                                            component={prop.component}
                                            key={key}
                                        />
                                    );
                                }
                                )}
                            </Switch>
                        </div>
                    </div>                
                </div>
            </div>
        </>
    )
}
const Layout = () => {      
    return (
        <>
            <Router>            
                <Switch>
                    <Route exact path='/' component={Landing} />
                    <Route exact path='/home' component={Home} />
                </Switch>            
            </Router>               
        </>
    )

}
export default Layout;

这是Pathrouter.js

import Feed from '../pages/Feed';
import Answer from '../pages/Answer';
import Addquestion from '../componants/Addquestion';
import Myprofile from '../componants/Myprofile';

var PathRouter = [
    {
      path: '/home/feed',
      name: 'Feed',
      component: Feed
    },
    {
      path: '/home/answer/:q_id',
      name: 'answer',
      component: Answer
    },
    {
      path: '/home/addquestion',
      name: 'addquestion',
      component: Addquestion
    },
    {
      path: '/home/myprofile',
      name: 'myprofile',
      component: Myprofile
    }
]
export default PathRouter;

在 Layout 组件中，行 <Route exact path='/home' component={Home} /> 破坏了您的嵌套路由。对于要渲染的嵌套路由，父路由也必须渲染，因为 '/home/feed' 不完全匹配 '/home' 父路由将不会被渲染。从 '/home' 路由中删除 exact。 – Jacob Smit
