[英]React router not working when deployed
我刚接触Heroku和进行部署。 我使用create-react-app和redux作为框架创建了一个项目。 部署到Heroku时,React路由器出现问题。 当我单击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,它将引发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”
您将必须以所有路由(或仅使用正在使用的路由)提供index.hml的方式配置Web服务器。
阅读该书以获得更多信息, 用于create-react-app的Heroku Buildpack:React.js Web应用程序的静态托管
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。
