MVC中的注销操作

Question

我使用简单的会话元素创建了我的登录名。我需要一个像我一样简单的注销过程。我如何创建与我的登录代码一致的注销？提前致谢。

下面是我的模型；

public class LoginModel
{
    public string UserName { get; set; }
    public string Password { get; set; }
    public string ErrorMessage { get; set; }
}

还有我的控制器在下面；

 public ActionResult Index()
    {
        Session["User"] = null;
        LoginModel model = new LoginModel();
        return View(model);
    }


    [HttpPost]
    public ActionResult Index(LoginModel data)
    {
        string user = System.Configuration.ConfigurationManager.AppSettings["UserName"];
        string password = System.Configuration.ConfigurationManager.AppSettings["Password"];
        if (data.UserName == user && data.Password == password)
        {
            Session["User"] = "1";
            return RedirectToAction("Index", "Home");
        }
        else
        {
            data.ErrorMessage = "Incorrect password or username entered. Please try again.";
            return View(data);
        }
    }

Answer 1

如果您对 "the user is logged in" 的定义是 "The UserID is stored in Session["User"]"，那么注销同样微不足道：只需清除会话变量，如 ASP.NET removing an item from Session?:

中所述

[HttpPost]
public ActionResult LogOut()
{
    Session.Remove("User");
}

MVC中的注销操作
