我有一个使用 create-react-app 引导的 React 应用程序。该应用程序运行在docker容器中，并已部署在子域中。假设域名是 http://mycompany.com ，那么我的 React 应用程序位于 http://mycompany.com/users/userid/apps/reactapp 。
有一个反向代理服务器可以进行 URL 重写，将基本 URL 更改为子域 URL。这就是我的 package.json 的样子 -

}
}
我面临的问题是，即使在我使用react-scripts start重新启动开发服务器后，任何JS文件更改都不会得到反映。仅当我重新启动 docker 容器时才会反映出来。在浏览器中，我检查过，bundle.js 文件没有最新的更改。我已经尝试过这些事情 -
我可以在开发服务器日志中看到，正在检测到文件更改，但这些更改并不用于提供给浏览器。即使我删除了一个文件（因此我可以在开发服务器日志中看到错误日志），但即使浏览器刷新，应用程序仍然没有任何更改。
您可能需要将以下内容添加到服务器端响应标头
"headers": { "/**": { "Cache-Control": "no-store, no-cache" } }如果问题仍然存在，您可以尝试清除浏览器缓存
