React Router URL参数不起作用

我'm unable to get the URL parameter feature in React Router to work, any insight would be helpful! I tried using the ' react-router-dom ' instead of ' react-router'但是我得到了这个家伙得到的错误:https://github.com/ReactTraining/react-router/issues/1799

当我做localhost:8000时,该应用程序工作 . 当我转到localhost:8000/123时,浏览器呈现 index.html as is with no react. Is Express干扰React?在快递我所拥有的是以下内容:

app.get('*', function response(req, res) {
  res.write(middleware.fileSystem.readFileSync(path.join(__dirname, 'dist/index.html')));
  res.end();
});

这是我的 main.js

import 'babel-polyfill';
import React from 'react';
import ReactDOM from 'react-dom';
import { Router, browserHistory } from 'react-router';
import Routes from './shared/components/Routes';
const ROOT_ELEMENT = 'app';
ReactDOM.render((
   <Router history={browserHistory}>
   {Routes}
   </Router>
), document.getElementById(ROOT_ELEMENT));

我的 routes.js

import { Route, IndexRoute, Link } from 'react-router';

import App from './App';
import HomePage from '../../pages/home/page';
import AboutPage from '../../pages/about/page';

const Child = ({ match }) => (
  <div>
    <h3>ID: {match.params.id}</h3>
  </div>
)

export default (
  <Route path="/" component={App}>
    <IndexRoute component={HomePage} />
    {/* <Route path="about" component={AboutPage} /> */}
    <Route path="/:id" component={Child} />
  </Route>
);

我的 Home 组件在不同的文件中定义如下(省略所有导入和生命周期函数):

export default React.createClass({
  render: function() {
     {* bunch of JSX goes here *}
  }
});

根据要求,我的 index.html 文件:

<html lang="en">
<head>
  <meta charset="utf-8">
  <meta http-equiv="x-ua-compatible" content="ie=edge">
  <title>Consent Form</title>
  <meta name="description" content="Privacy Consent Webform">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <!--Google Material Design Icons-->
  <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
</head>
<body>
  <div id="app"></div>
</body>
</html>

由于我的 webpack config (捆绑注入!),html没有捆绑包作为脚本标记(以下代码只是配置的一部分):

entry: [
    'webpack-hot-middleware/client',
    'bootstrap-loader',
    path.join(__dirname, 'src/main.js')
  ],
  output: {
    path: path.join(__dirname, '/dist/'),
    filename: '[name].js',
    publicPath: '/'
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: 'src/index.tpl.html',
      inject: 'body',
      filename: 'index.html'
    })

    当您向应用添加新路线时,您无法依靠热重新加载来注入新路线组件 . 我不得不按CTRL C再次运行 npm start .

    这解决了这个问题!!

    react-router-dom也是React Router v4包,而react-router是旧版本 . 感谢@HalCarleton指出这一点 . 我看到代码示例到处都有react-router,而官方文档显示react-router-dom,我真的很困惑为什么有两种不同类型的包 .
