IIS 抛出：
你调用的对象是空的。
当它应该将经过身份验证的用户重定向到 /Home/Index
我已经调查了它可能发生的原因，但找不到原因
这条线是：
return RedirectToAction("Index", "Home");
stacktrace：（这是我得到的唯一信息）

编辑 1： 该应用程序在我的计算机上本地运行。我正在处理所有文件夹并发送到服务器。然后，我尝试在服务器中本地访问，我得到了这个。服务器上的 IIS 对应用程序池具有相同的配置，我相信它的配置是正确的，至少像我一样在本地使用。我试图让它在服务器本地工作，然后我将配置为远程使用。

这是/首页/索引：
namespace gedaiapp.Controllers
{
[Authorize]
public class HomeController : Controller
{
public ActionResult Index()
{
return PartialView();
}
}
}
和 /Index/Login （类有授权属性，只有这个特定的方法有[AllowAnonymous]）所以尚未通过身份验证的用户可以登录
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public ActionResult Login(LoginModel model, FormCollection form)
{
try
{
//Verifica se logon será feito utilizando certificado digital ou não
string isDigitalCertified = form["hasDigital"];
if (!string.IsNullOrEmpty(isDigitalCertified))
{
string[] isDCArr = isDigitalCertified.Split(',');
if (!string.IsNullOrEmpty(isDCArr[0]))
{
string isDC = isDCArr[0];
//Se login for utilizando certificado digital
if (isDC == "true")
{
//Resgata subject do certificado digital
string certDadosStr = "";
do
{
certDadosStr = Request.ClientCertificate.Subject;
} while (certDadosStr == "");
//Resgata cpf ou cnpj do certificado digital
string[] certDadosArr = certDadosStr.Split(',');
int Count = certDadosArr.Count();
//Razão social é sempre o último elemento no padrão ICP-Brasil
string razaoSocial = certDadosArr[Count - 1];
string[] razaoSocialArr = razaoSocial.Split(':');

string key = razaoSocialArr[Count - 1];
//Resgata Guid do usuário
MembershipUser user = Membership.GetUser(model.UserName);

//Verifica se (cpf ou cnpj) do usuário efetuando o login é o mesmo do cadastrado no sistema
using (gedaiappEntities context = new gedaiappEntities())
{
var keyNumberObj = from a in context.sistema_UsersCertified
where a.userID == userID
select a.keyNumber;
string keyNumber = keyNumberObj.First();
//Se autenticidade for positiva (redireciona)
if (keyNumber == key)
{
FormsAuthentication.SetAuthCookie(model.UserName, false);
return RedirectToAction("Index", "Home");
}
else
{
return RedirectToAction("Login", "Account");
}
}
}//Caso login seja sem certificado digital
else
{
MembershipProvider mp = Membership.Provider;
if (mp.ValidateUser(model.UserName, model.Password))
{

try

return RedirectToAction("Index", "Home");
}
catch (Exception e)

return RedirectToAction("Login", "Account");

有什么帮助吗？
