【问题描述】：

我用node和mongo开发了一个api。

每当我尝试访问我的 api 时，我都会收到错误消息“您需要启用 JavaScript 才能运行此应用程序。”

虽然浏览器启用了 javascript，但我在邮递员中也遇到了同样的错误。

【问题讨论】：

您的浏览器必须禁用 Javascript。您可以通过进入设置启用它
这个错误是如何传递给浏览器的？您的应用程序正在将该响应返回给浏览器，对吗？是在text/html 响应的noscript 部分吗？是否涉及 react 或 create-react-app？
我发现问题出在我的节点 API 上，因为当我从邮递员调用节点 API 时，它会产生相同的错误。
我已经编辑了问题并解决了整个错误。

标签： javascript node.js

【解决方案1】：

您可以检查端口是否正确。我有一个类似的问题，我的节点（快速）服务器在端口 8000 上，我的反应客户端在端口 3000 上。客户端被代理到服务器，都在本地主机上。我正在请求http://localhost:3000/somedata（并且收到“您需要启用 Javascript 才能运行此应用程序”），但实际上我要查看数据，我只需键入 http://localhost:8000/somedata 即可在浏览器中查看它。

我知道这篇文章很老了，但万一它对某人有帮助......
