reactjs - static.json 不适用于 ReactJS 路由和 Heroku

Question

理论上这应该可行，在 / 文件夹中添加文件 /static.json 使一切都转到 React index.html.

React Routing works in local machine but not Heroku

https://github.com/heroku/heroku-buildpack-static#configuration

在我的例子中它不起作用，我收到了 Cannot GET/hello 而不是收到 index.html。令人惊讶的是，如果我直接转到 /index.html，我会得到该页面，但没有激活任何路由。

发生了什么，我该如何解决？

UPDATE: tried without luck /static.jason /src/static.jason /client/static.jason /client/src/static.jason

/static.json

{
  "routes": {
    "/**": "index.html"
  }
}

/client/src/index.js

import React from 'react';
import ReactDOM from 'react-dom';
import FileUpload from './FileUpload';

ReactDOM.render(
  <div><FileUpload /></div>,
  document.getElementById('root')
);

/client/src/FileUpload.mjs

import React, { Component } from 'react';
import { BrowserRouter as Router, Route } from 'react-router-dom';

class TextFileReader extends Component {
 render() {
  return (
   <Router>
    <div>
     <Route path="/heyyo" render={() => <span>heyyo</span>} />
     <Route exact path="/" render={() => <div>resting</div>} />
     <Route path="/what" render={() => <div>what</div>} />
      NO ROUTES HERE
    </div>
   </Router>
  )
 }
}

export default TextFileReader;

最后，重新阅读更好的 React Routing works in local machine but not Heroku我已将此行添加到我的 Express

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);
});

一旦部署到 Heroku，它就可以工作了:)
