Question

我遇到的问题是，当使用react-router-dom@4.2.2时，我无法导航到路径大于1的路径，这样就是这样的问题：此外，这是我在解决此问题的回购的Github链接

https://github.com/ShawnCholeva/React-Typescript-Webpack4-Router

import React, { Component } from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
//All routes work if I use HashRouter here instead of BrowserRouter

class App extends Component {
    render() {
        return (
            <Router>
                <Switch>
                    <Route exact path='/' component={ Login }/> <--- Works
                    <Route exact path='/accountSetup/:guid?' component={ AccountSetup }/> 
                    ^-- Above works when just '/accountSetup' but fails when I do '/accountSetup/123'
                    <Route component={ NotFound } /> <--- Works
                </Switch>
            </Router>
        );
    }
}

所以我注意到这只在我使用HashRouter而不是BrowserRouter时才有效。因此，我认为可能是我通过webpack-dev-server@3.1.1提供应用程序的方式。所以我看到我必须使用webpack@4.2.0将historyApiFallback属性添加到我的devServer属性对象中，如下所示：

devServer: {
    compress: true,
    port: 8080,
    historyApiFallback: true,
    contentBase: path.resolve(__dirname),
    publicPath: '/',
}

然后我通过我的package.json中的npm脚本运行应用程序，如下所示：

"start": "webpack-dev-server --open --mode development"

因此，当我导航到localhost：5000 / accountSetup / 123时，我在控制台中收到以下错误：

我还尝试使用http-server-spa包提供此功能，并在导航时注意到以下日志：

[OK] Serving static files from ./dist
[OK] Using the fallback file index.html
[OK] Listening on http://localhost:8080
----------------------------------------------
[OK] GET /accountSetup
[OK] GET /bundle.js
[OK] GET /accountSetup/123
[ER] GET /accountSetup/bundle.js

似乎是将最后一个路由参数的url中的前缀添加到路由加载bundle.js中。所以你可以看到当我导航到accountSetup时，它只是引用了bundle.js，因为它是url中的最后一个段。但是当我添加多个段时，它似乎将从localhost到最后一个段的先前段附加到bundle.js的路径

编辑：

似乎是使用动态路由的BrowserRouter与使用静态路由的HashRouter相关的事情。

我想我已经找到了这个问题。您的webpack配置中缺少publicPath。这是更新的输出配置：

output: {
   filename: 'bundle.js',
   path: path.resolve(__dirname, 'dist'),
   publicPath: '/' <-- ADDED THIS
  },

Answer 2

看起来你正在尝试制作嵌套路线。但是在ReactRouter v4中你指出使用动态路由嵌套路由应该嵌套在组件内部。您应该添加AccountSetup渲染方法的含义。

render(){
 //...
  <Route
    path={match.url + '/test'}
    component={Test}
  />
// ...
}

阅读docs中有关嵌套路线的更多信息。这是一个live example 如果您确实想要使用静态路由，可以try this。
