launchSettings.json 仅使用文件通过VS.当您发布应用程序（或在没有VS的情况下运行）时，未使用launchSettings.json 。使用IIS / IISExpress运行时，只需确保web.config具有正确的设置。在您的情况下，web.config中的 forwardWindowsAuthToken 属性丢失或设置为 false 。必须将其设置为 true 才能使Windows身份验证生效。发布前的示例web.config如下所示：

launchSettings.json file is only used by VS. When you publish your app (or run without VS) launchSettings.json is not being used. When you run with IIS/IISExpress you just need to make sure that your web.config has correct settings. In your case the forwardWindowsAuthToken attribute in the web.config is missing or is set to false. It must be set to true for Windows Authentication to work. A sample web.config before publishing would look like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified"/>
    </handlers>
    <aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="true"/>
  </system.webServer>
</configuration>
