Asp.net core mvc 使用Identity Server 4登录SharePoint 2013时出错

尝试使用Identity Server 4登录SharePoint 2013时出错，这是一个错误“此方法只能在System.Web.HttpRequest.get_LogonUserIdentity（）+258的身份验证事件

后调用”

在IIS上托管identity server mvc core应用程序时发生错误。从VisualStudio运行时，它工作正常。有人能提供建议或帮助吗

编辑：

这是帐户控制器中的登录操作

[HttpGet]
    public async Task<IActionResult> Login(string returnUrl)
    {
        var vm = await _account.BuildLoginViewModelAsync(returnUrl);

        if (vm.IsExternalLoginOnly)
        {
            // only one option for logging in
            return await ExternalLogin(vm.ExternalProviders.First().AuthenticationScheme, returnUrl);
        }
         if(!string.IsNullOrEmpty(Request.Query["culture"])) ViewBag.QueryString = Request.QueryString.Value.Replace("&culture=en", "").Replace("&culture=ar", "") + "&culture=" + Request.Query["culture"];
        else ViewBag.QueryString = Request.QueryString.Value.Replace("&culture=en", "").Replace("&culture=ar", "") + "&culture=en";
        return View(vm);

                // make sure the returnUrl is still valid, and if yes - redirect back to authorize endpoint
                if (_interaction.IsValidReturnUrl(model.ReturnUrl))
                {
                    return Redirect(model.ReturnUrl);
                }

                return Redirect("~/");
            }

            ModelState.AddModelError("", AccountOptions.InvalidCredentialsErrorMessage);
        }
        ViewBag.QueryString = Request.QueryString.Value;
        // something went wrong, show form with error
        var vm = await _account.BuildLoginViewModelAsync(model);
        return View(vm);

我已经能够通过修改SharePoint站点的重定向Url并将default.aspx从Url中删除为http://{{SP site}}/{u trust而不是http://{{SP site}}/{u trust/default.aspx

你能发布你的代码吗？@moritzg我已经在问题中添加了身份验证逻辑，如果您需要更多详细信息，请告诉我错误的完整堆栈跟踪也会很有帮助！我添加了错误详细信息和错误完整堆栈OK奇怪的错误，我在
