我们正在从ASP.NET迁移到ASP.NET核心。
我们需要为不同的路径配置不同的身份认证

<location path="controllerpath/method">
    <system.webServer>
        <security>
            <authentication>
                <anonymousAuthentication enabled="true" />
            </authentication>
        </security>
    </system.webServer>
</location>

但是一旦我们添加了<location path="xyz">条目，指定的路径就不再是可达的了，调用者得到一个404错误。

<location path="xyz/abc">
</location>

如果我删除了这个条目，就可以再次访问404。404直接来自IIS，因为即使应用程序无法启动（例如，所有其他调用都会导致503），通过location path指定的路径仍然会导致404。
下面是完整的web.config：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location inheritInChildApplications="false">
    <system.webServer>
      <handlers>

      </handlers>
      <security>
        <requestFiltering>
          <requestLimits maxAllowedContentLength="52428800"/>
        </requestFiltering>
        <authorization>
          <add accessType="Allow" users="*" verbs="OPTIONS"/>
        </authorization>
      </security>
