我是Heroku和部署的新手。我使用create-react-app创建了一个项目，并使用redux作为框架。部署到Heroku时，我遇到了反应路由器的问题。当我点击我的应用程序中的链接时，路由器可以工作，但是当我刷新页面时，它会抛出404 Not Found错误。
这是我的index.js
import { Router, Route, browserHistory, IndexRoute } from 'react-router'
import { syncHistoryWithStore } from 'react-router-redux'
import { Provider } from 'react-redux'
import ReactDOM from 'react-dom'
import React from 'react'
import App from './containers/App'
import configure from './store'
import Dashboard from './components/v1/dashboard/dashboard';
import Login from './components/v1/login/login';
const store = configure();
const history = syncHistoryWithStore(browserHistory, store);
ReactDOM.render(
<Provider store={store}>
<Router history={history}>
<Route path="/" component={App}>
<IndexRoute component={Login} />
<Router path="/dashboard" component={Dashboard}/>
</Route>
</Router>
</Provider>,
document.getElementById('root')
)
这是我的webpack.config.prod.js

问题是您的网络服务器仅为根路由（“/”）提供“index.html”
您必须以所有路由（或仅使用的路由）将为index.hml提供服务的方式配置Web服务器

Server.js：
app.get("*", (req, res) => {
let url = path.join(__dirname, '../client/build', 'index.html');
if (!url.startsWith('/app/')) // we're on local windows
url = url.substring(1);
res.sendFile(url);
});
为我工作。
