Question

我正在使用反应路由器进行练习，需要有一个:id参数。它与网址中的ID匹配，例如/edit/2，但不包含/edit的基本情况。

主应用路由器文件

import React from 'react';
import {BrowserRouter, Route, Switch, Link, NavLink} from 'react-router-dom';
import landingPage from '../components/landingPage';
import editPage from '../components/editPage';
import createPage from '../components/createPage';
import helpPage from '../components/helpPage';
import notFoundPage from '../components/notFoundPage';
import Header from '../components/header';


const AppRouter = () => (
    <BrowserRouter>
        <div>
            <Header/>
            <Switch>
                <Route exact={true} path="/" component={landingPage}/>
                <Route path="/create" component={createPage}/>
                <Route exact={false} path="/edit/:id" component={editPage}/>
                <Route path="/help" component={helpPage}/>
                <Route component={notFoundPage}/>
            </Switch>
        </div>
    </BrowserRouter>
);

export default AppRouter;

编辑页面代码

import React from 'react';

const editPage = (props) => {
    console.log(props)
    return (
    <div>Edit Page</div>
    );
}
export default editPage;

如果您使用的是React Router＆gt; = v4，则可以make a parameter optional在参数名称后添加?：

<Route exact={false} path="/edit/:id?" component={editPage}/>

React路由器不匹配基本路径
