html - 如何使登录页面显示在单独的页面上（当前有旁边菜单） ASP.net MVC

Question

目前，当我尝试进入登录页面时，它会在开始时显示在单独的页面上（参见预期结果中的图片）。当我单击“注销”或用户未获得授权时，登录页面会显示我的站点菜单。

我还注意到，如果我只是刷新页面，它会进入正确的全页登录屏幕。

我查看了我的 Web.Config，那里的一切看起来都很好：

<authentication mode="Forms"> <forms loginUrl="~/Account/Login" timeout="2880" /> </authentication>

我最近更改了所有登录程序，并相信 ReturnUrl 中仍然存在问题，但我似乎找不到问题。我将旧代码与新代码进行了比较，没有看到任何变化。

账户控制人：

// GET: /Account/Login
    [AllowAnonymous]
    public ActionResult Login(string returnUrl)
    {
        EnsureLoggedOut();            
        ViewBag.ReturnUrl = returnUrl;
        // Store the originating URL so we can attach it to a form field
        var viewModel = new LoginViewModel { ReturnUrl = returnUrl };

        return View(viewModel);
    }

    // POST: /Account/Login
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
    {
        if (!ModelState.IsValid)
        {
            return View(model);
        }

        ApplicationUser user = new ApplicationUser();
        try
        {
            user = DBcontext.Users.Where(u => u.Email.Equals(model.Email)).Single(); // where db is ApplicationDbContext instance

        }
        catch (InvalidOperationException)
        {
            // the user is not exist
            return View("The user does not exist.");
        }

        var result = await SignInManager.PasswordSignInAsync(user.UserName, model.Password, model.RememberMe, shouldLockout: false);

        SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
        switch (result)
        {
            case SignInStatus.Success:
                return RedirectToLocal(returnUrl);
            case SignInStatus.LockedOut:
                return View("Lockout");
            case SignInStatus.RequiresVerification:
                return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
            case SignInStatus.Failure:
            default:
                ModelState.AddModelError("", "Invalid login attempt.");
                return View(model);
        }
    }

    // POST: /Account/LogOff
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult LogOff()
    {
        AuthenticationManager.SignOut(DefaultAuthenticationTypes.ApplicationCookie);
        return RedirectToAction("Index", "Home");
    }

    private ActionResult RedirectToLocal(string returnUrl)
    {
        if (Url.IsLocalUrl(returnUrl))
        {
            return Redirect(returnUrl);
        }
        return RedirectToAction("Index", "Home");
    }


    private void EnsureLoggedOut()
    {
        // If the request is (still) marked as authenticated we send the user to the logout action
        if (Request.IsAuthenticated)
            LogOff(); 
    }
}

预期结果：（也是第一次访问网站时的结果。）

当前结果：

感谢您提前提供任何帮助。

更新： 这似乎是一个身份验证问题。如果用户通过身份验证，则显示菜单。开始了一个新线程，试图解决这里的身份验证问题。
