我有一個使用 create-react-app 引導的 React 應用程式。該應用程式運行在docker容器中，並已部署在子網域中。假設網域是 http://mycompany.com ，那麼我的 React 應用程式位於 http://mycompany.com/users/userid/apps/reactapp 。
有一個反向代理伺服器可以進行 URL 重寫，將基本 URL 變更為子網域 URL。這就是我的 package.json 的樣子 -

我面臨的問題是，即使在我使用react-scripts start重新啟動開發伺服器後，任何JS檔案變更都不會被反映。只有當我重新啟動 docker 容器時才會反映出來。在瀏覽器中，我檢查過，bundle.js 檔案沒有最新的變更。我已經嘗試過這些事情 -
我可以在開發伺服器日誌中看到，正在偵測到檔案更改，但這些更改並不用於提供給瀏覽器。即使我刪除了一個檔案（因此我可以在開發伺服器日誌中看到錯誤日誌），但即使瀏覽器刷新，應用程式仍然沒有任何更改。
您可能需要將以下內容新增至伺服器端回應標頭
"headers": { "/**": { "Cache-Control": "no-store, no-cache" } }如果問題仍然存在，您可以嘗試清除瀏覽器快取
