找不到网址的网页服务器未返回index.html

问题描述

我分别构建了react（前端）和asp.netcore webapi（后端），并将webapi发布到本地文件夹，并复制到远程服务器（plesk面板）上的httpdocs。

然后在dist文件夹的前端复制内容（即index.html和main-bundle.js文件上使用“ npm run build”命令。

现在前端工作或后端工作如下： 如果我使用默认的web.config文件，则网站前端可以运行，但是webApi.dll不起作用，因此api调用获取数据不起作用。 如果我使用以下web.config文件，则后端可以工作，但服务器不会重新调整index.html文件，因此，在新设备或浏览器上加载时显示http 404错误。 web.config如下：

我发现webapi没有index.html服务的原因。如果它已经加载到浏览器中，则该网站可以正常运行。 httpdocs文件夹包含index.html和main-bundle.js文件，服务器无法提供这些文件。 所以我认为我们必须查看用于webapi而不是spa模板的startup.cs文件。 这是startup.cs
