javascript - 无法导航到 react-router-dom URL

Question

SO 上有一些主题，例如 this one建议更改 Webpack 和 this one建议设置一个包罗万象的。

我正在为三个路由使用 react-router-dom；与此处的其他问题类似，/ 路径有效，但 /cars 或 /about 均无效。

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


const Home = () => (
  <h1>Home</h1>
)

const Car = () => (
  <h1>Cars</h1>
)

const About = () => (
  <h1>About</h1>
)

render(
  <BrowserRouter>
    <Switch>
      <Route exact path="/" component={Home}/>
      <Route exact path="/cars" component={Car}/>
      <Route path="/about" component={About}/>
    </Switch>
  </BrowserRouter>,
  document.getElementById('container')
);

我尝试将 publicPath 和 historyApiFallback 添加到我的 webpack 配置中:

module.exports = {
  entry: ['./src/index.jsx'],
  output: {
    path: path.resolve('public'),
    filename: 'bundle.js',
    publicPath: '/'
  },
  module: {
    loaders: [
      {test: /\.js$/,loader: 'babel-loader',exclude: /node_modules/},
      {test: /\.jsx$/,loader: 'babel-loader',exclude: /node_modules/}
    ]
  },
  devServer: {
    historyApiFallback: true
  }
}

但是当我导航到 http://localhost:8080/cars 时，我在浏览器上收到了一条 Cannot GET/cars 消息和大量类似的错误对此:

Note that 'font-src' was not explicitly set, so 'default-src' is used as a fallback.

Answer 1

通常在尝试自己解决这个问题 30 分钟后，感到沮丧并在 SO 上发帖；我在 2 分钟后...!

我添加到我的 webpack 文件中的配置毫无意义；看到我正在使用 express

提供我的文件

catch-all 方法正是我所需要的，但我做错了。你有两个选择。执行适当的“全部捕获”并将所有内容发送到 HTML 文件...

app.get('*', (req, res) => {
  res.sendFile(appRootPath + '/public/index.html');
});

或者，如果像我一样，您只想发送一个特定的端点，这样您仍然可以管理“其他事情”，您可以...

app.get('/react*', (req, res) => {
  res.sendFile(appRootPath + '/public/index.html');
});

具体提及，因为这就是让我失望的原因，请确保您执行 /react*/ 而不是 /react/*

然后我可以将我的路线更新为以下内容并直接浏览到它们...

render(
  <BrowserRouter>
    <Switch>
      <Route exact path="/react" component={Home}/>
      <Route exact path="/react/car" component={Car}/>
      <Route path="/react/about" component={About}/>
    </Switch>
  </BrowserRouter>,
  document.getElementById('container')
);
