我正试图让blazor在IIS中托管的现有MVC应用程序中工作。我以为例
剃须刀页也有一个类似的例子。两者在IIS express和自托管中都能很好地工作，但当我尝试在IIS中使用它们时，它们失败了。
当托管在IIS中时，框架将注册到站点，而不是应用程序。当在chrome中打开时，控制台会出现以下错误：
blazor.server.js:1加载资源失败：服务器响应状态为503(服务不可用(favicon.ico:1加载资源失败：服务器响应状态为503(服务不可用(
我尝试将框架脚本引用从<script src="_framework/blazor.server.js"></script>更改为<script src="~/_framework/blazor.server.js"></script>。这解决了最初的错误，但blazor在下一步失败了：
[2020-03-05T09:46:07.566Z] Information: Normalizing '_blazor' to 'http://localhost/_blazor'.

信号集线器似乎指向IIS中的根站点路径，而不是应用程序路径。
有人知道我该怎么解决吗？要重新创建问题，只需在此处下载源代码并设置指向IIS 的调试配置

感谢来自mars的agua的评论，解决方案是将以下标签添加到_layout.cshtml 的头部
例如
<head>
<meta charset="utf-8" />
<base href="~/" />
