ASP.NET MVC Windows身份验证拒绝工作

我使用Visual Studio 2015创建了一个MVC Web应用程序。我的目标是根据需要将身份验证模式从无更改为Windows身份验证，这样我就可以使用@User.Identity.Name方法来识别用户。到目前为止我尝试过的东西的简短总结：

项目属性

• 设置匿名身份验证：禁用
• 设置Windows身份验证：已启用

Web.config

• 将maxUrlLength="65536">属性添加到httpRuntime标记
• 将maxQueryStringLength="10240">属性添加到httpRuntime标记
• 在<system.web>标签中添加<authentication mode="Windows"/>

• 添加system.webServer标记(每当我添加它时，它都会以ERR_TOO_MANY_DIRECTS结束(：

  <system.webServer>
      <security>
        <requestFiltering>
          <requestLimits maxUrl="10999" maxQueryString="2097151" />
        </requestFiltering>
      </security>
  </system.webServer>
  

Windows

1. 在"控制面板"中打开"程序和功能">
2. 选择">转弯Windows功能打开或关闭"。
3. 导航到Internet Information Services>World Wide Web Services>Security，并确保已选中Windows身份验证节点

IIS Express

我尝试从头开始创建一个新项目，并在项目设置过程中巧妙地选择了Windows身份验证。这很好，所以我相信我的IISExpress设置是100%正确的。我甚至检查了applicationhost.config文件，但它没有我的特定项目的条目。同样，如果在创建新项目时选择正确的身份验证，它也可以正常工作。

以上似乎都不起作用，当我尝试运行Visual Studio项目时，所有这些都会出现IIS错误：

HTTP Error 404.15 - Not Found
The request filtering module is configured to deny a request where the query string is too long.

这就是IIS错误页面中的URL：

http://localhost:52728/Account/Login?ReturnUrl=%2FAccount%2FLogin%3FReturnUrl%3D%252FAccount%252FLogin%253FReturnUrl%253D%25252FAccount%25252FLogin%25253FReturnUrl%25253D%2525252FAccount%2525252FLogin%2525253FReturnUrl%2525253D%252525252FAccount%252525252FLogin%252525253FReturnUrl%252525253D%25252525252FAccount%25252525252FLogin%25252525253FReturnUrl%25252525253D%2525252525252FAccount%2525252525252FLogin%2525252525253FReturnUrl%2525252525253D%252525252525252FAccount%252525252525252FLogin%252525252525253FReturnUrl%252525252525253D%25252525252525252FAccount%25252525252525252FLogin%25252525252525253FReturnUrl%25252525252525253D%2525252525252525252FAccount%2525252525252525252FLogin%2525252525252525253FReturnUrl%2525252525252525253D%252525252525252525252FAccount%252525252525252525252FLogin%252525252525252525253FReturnUrl%252525252525252525253D%25252525252525252525252FAccount%25252525252525252525252FLogin%25252525252525252525253FReturnUrl%25252525252525252525253D%2525252525252525252525252FAccount%2525252525252525252525252FLogin%2525252525252525252525253FReturnUrl%2525252525252525252525253D%252525252525252525252525252FAccount%252525252525252525252525252FLogin%252525252525252525252525253FReturnUrl%252525252525252525252525253D%25252525252525252525252525252FAccount%25252525252525252525252525252FLogin%25252525252525252525252525253FReturnUrl%25252525252525252525252525253D%2525252525252525252525252525252FAccount%2525252525252525252525252525252FLogin%2525252525252525252525252525253FReturnUrl%2525252525252525252525252525253D%252525252525252525252525252525252FAccount%252525252525252525252525252525252FLogin%252525252525252525252525252525253FReturnUrl%252525252525252525252525252525253D%25252525252525252525252525252525252FAccount%25252525252525252525252525252525252FLogin%25252525252525252525252525252525253FReturnUrl%25252525252525252525252525252525253D%2525252525252525252525252525252525252FAccount%2525252525252525252525252525252525252FLogin%2525252525252525252525252525252525253FReturnUrl%2525252525252525252525252525252525253D%252525252525252525252525252525252525252FAccount%252525252525252525252525252525252525252FLogin%252525252525252525252525252525252525253FReturnUrl%252525252525252525252525252525252525253D%25252525252525252525252525252525252525252F

正如你所知，我得到了一个无限的重定向循环，这可能是我无法使其工作的原因。但是我不知道是什么原因造成的。我们非常感谢您的帮助。

 app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
        LoginPath = new PathString("/Account/Login")
    });
    app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
