react-router-dom BrowserRouter 不导航到具有多个 url 参数的路径

Question

我遇到一个问题，在使用 react-router-dom@4.2.2 时，我无法导航到路径大于 1 个部分的路线：此外，这是 Github link 到我遇到这个问题的仓库。

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>
        );
    }
}

所以我注意到这仅在我使用 HashRouter 而不是 BrowserRouter 时才有效。所以这让我想到这可能是我通过 webpack-dev-server@3.1.1 为应用程序提供服务的方式。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: '/',
}

然后我运行通过我 package.json 中的 npm 脚本应用程序，如下所示：

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

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

我也曾尝试使用 http-server-spa 包提供此服务，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

好像是把最后一个路由参数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 中的最后一段。但是当我添加多个段时，它似乎将先前的段从 localhost 附加到最后一个段，到 bundle.js

的路径

编辑：

似乎与使用动态路由的 BrowserRouter 和使用静态路由的 HashRouter 有关。

您似乎在尝试创建嵌套路由。但是在 ReactRouter v4 中，正如您指出的那样使用动态路由，嵌套路由应该嵌套在组件内部。在你的AccountSetup渲染方法中你应该添加的意思。

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

在 docs. Here is a live example 中阅读有关嵌套路由的更多信息。
如果你确实想使用静态路由，你可以 try this.

我想我已经找到问题所在了。您的 webpack 配置中缺少 publicPath。这是更新后的输出配置：

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