我的 Angular 应用在 ng serve 中运行良好。但是在 ng 构建并放入 IIS 之后，只有索引页面可以访问，而其他所有页面都无法访问。不太确定这个问题，有什么建议吗？

【问题讨论】：

这是 IIS 问题，不是 Angular。
@BojanKogoj 谢谢。我在帖子中添加了 IIS 设置。不太确定我是否错过了什么
你在使用路由吗？您的 IIS 是否配置为 URL 重写？有关详细信息，请参阅此处的文档：angular.io/guide/…
你能分享你放在IIS上的文件吗？你做了ng build，只复制了dist文件夹的内容？
我不熟悉 IIS，但是您是否将所有子页面都重定向到 index.html？你应该让 Angular 路由器从那里处理它。

【解决方案1】：

好像你没有配置url重写，然后IIS尝试在根文件夹下找到项目文件夹，而不是将其路由到angular。

尝试在 web.config 中添加它。您可以根据需要更改重写的url。

<rewrite>
<rules>
  <rule name="Angular Routes" stopProcessing="true">
    <match url=".*" />
    <conditions logicalGrouping="MatchAll">
      <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
      <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
    </conditions>
    <action type="Rewrite" url="./index.html" />
  </rule>
</rules>
