当基于角色的授权失败时，asp.net core 2.0 应用程序崩溃

Question

我想根据角色授权用户：

[Authorize(Roles = "Administrator")]
public class TestController : Controller
{    
    public IActionResult Index()
    {
        return Ok();
    }
}

当用户拥有Claim(type: "Role", value: "Administrator") 时，它可以正常工作。当他不这样做时，应用程序崩溃。在 VS 中调试时，它会停止并且 IIS Express 进程结束。我没有看到任何例外。我只看到这个输出调试输出：

编辑： 我注意到在使用 AddOpenIdConnect 身份验证生成器时会发生这种情况。当我将其注释掉时，它会将我重定向到一些默认的“禁止”网址

services.AddAuthentication(sharedOptions =>
{
    sharedOptions.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    sharedOptions.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
})
  .AddCookie(option => option.Cookie.SameSite = SameSiteMode.None)
  .AddOpenIdConnect(option =>
  {
      option.ClientId = config.ClientId;
      option.Authority = String.Format(config.AadInstance, config.Tenant);
      option.SignedOutRedirectUri = config.PostLogoutRedirectUri;
      option.Events = new OpenIdConnectEvents
      {
          OnRedirectToIdentityProvider = redirectContext =>
          {
              bool isAjaxRequest = redirectContext.HttpContext.Request.Headers["x-requested-with"] == "XMLHttpRequest";
              if (isAjaxRequest)
              {
                  redirectContext.HttpContext.Response.StatusCode = StatusCodes.Status401Unauthorized;
                  redirectContext.HttpContext.Response.Headers["Location"] = "/Account/Login";
                  redirectContext.HandleResponse();
              }
              return Task.CompletedTask;
          }
      };
  });

来自github: Core CLR crashes when using Authorize attribute and OpenIdConnect

这是在 2.0.1 中由 #1435 修补的 https://www.nuget.org/packages/Microsoft.AspNetCore.Authentication.OpenIdConnect/

解决方法是设置 sharedOptions.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;

我已经验证了解决方法并且它有效
