React-Router-dom v4嵌套路由不起作用

reactjs

我也遇到同样的问题。

https://reacttraining.com/react-router/web/guides/quick-
start促销react- router-dom

同样，人们发现list down routes在一个文件中而不是在组件中更好。

提到的东西： https :
//github.com/ReactTraining/react-router/tree/master/packages/react-router-
config

起作用的东西（大部分）：

import * as React from 'react'
import {BrowserRouter as Router, Route, Switch } from 'react-router-dom'


export const Routes = () => (
  <Router>
    <div>
      <Switch>
        <Route exact path="/login" component={Login}/>
        <MainApp path="/">
          <Route path="/list" component={List}/>
          <Route path="/settings" component={Settings}/>
        </MainApp>
        <Route path="*" component={PageNotFound}/>
      </Switch>
    </div>
  </Router>
)

无法正常工作： site.com/SomeGarbagePath 显示<MainApp>我的想法。
<Route path="*" component={PageNotFound}/>

更新资料

/ - Home - parent of all (almost)
/List - inside home
/Settings - inside home
/Login - standalone
/Users - inside home, For now just showing itself. It has further pages.
/User/123 - inside user with /:id
/User/staticUser - inside user with static route
/garbage - not a route defined (not working as expected)

这是一种完成您描述的方式（请注意，还有其他直接在React Components中处理布局的方式）。为了使示例简单，将其他组件（<Home>, <List>等）创建为没有功能或状态的纯功能组件，但是将每个组件作为适当的React组件放在自己的文件中将是微不足道的。下面的示例已完成并将运行。

import React, { Component } from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

class App extends Component {
  render() {

    const Header = () => <h1>My header</h1>;
    const Footer = () => <h2>My footer</h2>;
    const Login = () => <p>Login Component</p>;    
    const Home = () => <p>Home Page</p>;
    const List = () => <p>List Page</p>;
    const Settings = () => <p>Settings Page</p>;
    const PageNotFound = () => <h1>Uh oh, not found!</h1>;

    const RouteWithLayout = ({ component, ...rest }) => {
      return (
        <div>
          <Header />
          <Route {...rest} render={ () => React.createElement(component) } />
          <Footer />
        </div>
      );
    };

    return (
      <Router>
        <div>
          <Switch>
            <Route exact path="/login" component={Login} />
            <RouteWithLayout exact path="/" component={Home} />
            <RouteWithLayout path="/list" component={List} />
            <RouteWithLayout path="/settings" component={Settings} />
            <Route path="*" component={PageNotFound} />
          </Switch>
        </div>
      </Router>    
    );
  }
}

export default App;

这将执行以下操作，希望这是您的问题中现在描述的内容：

/login 没有页眉或页脚。
/，/list和/settings都有页眉和页脚。
找不到任何路由都将显示该PageNotFound组件，而没有页眉或页脚。
