找不到路径"/Home"的控制器或未实现 IController

Question

我搜遍了互联网，检查了所有以前回答过的相同标题的问题，但我无法弄清楚这个问题。

我返回RedirectToAction("Index"， "Home")从我的身份验证控制器的操作方法，然后收到以下异常:

Server Error in '/' Application.
The controller for path '/Home' was not found or does not implement IController.

认证控制器如下所示:

    public class AuthenticationController : Controller
{
    private ILogService _logService;
    private IEmailProvider _emailProvider;
    private IMembershipProvider _membershipProvider;
    private IAuthenticationProvider _authenicationProvider;
    public AuthenticationController(ILogService logService, IEmailProvider emailProvider, IMembershipProvider membershipProvider, IAuthenticationProvider authenicationProvider)
    {
        _logService = logService;
        _emailProvider = emailProvider;
        _membershipProvider = membershipProvider;
        _authenicationProvider = authenicationProvider;
    }
    [AllowAnonymous]
    [HttpGet]
    ////[OutputCache(Duration = 3600, VaryByParam = "none")]
    public ActionResult Index()
    {
        return View();
    }
    [AllowAnonymous]
    [HttpPost]
    [ValidateHttpAntiForgeryToken] 
    public ActionResult Login(LoginModel model, string returnUrl)
    {
        if (Request.IsAuthenticated)
        {
            return RedirectToAction("Index", "Home");
        }
        if (ModelState.IsValid)
        {
            if (_membershipProvider.ValidateUser(model.Username, model.Password))
            {
                _authenicationProvider.AuthenticateUser(model.Username);
                ////this.HttpContext.User = new GenericPrincipal(new GenericIdentity(model.Username), null);
                if (!string.IsNullOrEmpty(returnUrl))
                {
                    if (Url.IsLocalUrl(returnUrl))
                    {
                        return Redirect(returnUrl);
                    }
                    else
                    {
                        _logService.Log(new SecurityException(string.Format("Open redirect to {0} detected (Username {1})", returnUrl, model.Username)));
                        return View("Index", model);
                    }
                }
                else
                {
                    return RedirectToAction("Index", "Home");
                }
            }
            else
            {
                ModelState.AddModelError(string.Empty, Resources.Controller.View.Authentication.Index.IncorrectUsernamePassword);
            }
        }
        return View("Index", model);
    }
    [AllowAnonymous]
    [HttpPost]
    [ValidateHttpAntiForgeryToken] 
    public ActionResult ForgotPassword(LoginModel model)
    {
        if (ModelState.IsValidField("Username"))
        {
            if (!_membershipProvider.EnablePasswordRetrieval)
            {
                throw new Exception(Resources.Controller.View.Authentication.Index.PasswordRetreivalNotAllowed);
            }
            IMembershipUser user = _membershipProvider.FindUsersByName(model.Username).FirstOrDefault();
            if (user != null)
            {
                try
                {
                    _emailProvider.Send(ConfigurationHelper.GetSmtpSettings().Smtp.From, user.EmailAddress, Resources.Global.PasswordRecoveryEmailSubject, user.GeneratePasswordRetreivalEmail());
                    ModelState.AddModelSuccess(Resources.Controller.View.Authentication.Index.PasswordSentViaEmail);
                }
                catch (Exception ex)
                {
                    _logService.Log(ex);
                    ModelState.AddModelError(string.Empty, Resources.Controller.View.Authentication.Index.UnableToRetreivePassword);
                }
            }
            else
            {
                ModelState.AddModelError(string.Empty, Resources.Controller.View.Authentication.Index.EmailAddressDoesNotExist);
            }
        }
        ViewBag.ShowForgottenPasswordForm = "true";
        return View("Index", model);
    }
    [HttpGet]
    public ActionResult Logout()
    {
        _authenicationProvider.Logout();
        ModelState.AddModelInformation(Resources.Controller.View.Authentication.Index.Logout);
        return View("Index");
    }
}

我的HomeController如下所示:

public class HomeController : Controller
{
    private IMembershipProvider _membershipProvider;
    private IAuthenticationProvider _authenticationProvider;
    public HomeController(IMembershipProvider membershipProvider, IAuthenticationProvider authenticationProvider)
    {
        _membershipProvider = membershipProvider;
        _authenticationProvider = authenticationProvider;
    }
    public ActionResult Index()
    {
        return View(_membershipProvider.GetCurrentUser());
    }
}

见下面的RouteConfig:

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}",
            defaults: new { controller = "Authentication", action = "Index" });
    }
}

RouteDebugger对{controller}/{action}和{*catchall}路由返回TRUE，并确认AppRelativeCurrentExecutionFilePath为:~/Home

我已经调试了代码，我可以成功调试并进入HomeController构造函数和Index动作方法。我还可以进入"~/Views/Home/Index"。Cshtml "，但是它会在代码行抛出异常:

<span class="username">@Model.UserName</span>

有趣的是，在进入这段代码之前，我可以添加"@Model"。到我的手表列表，我可以看到对象和它的属性很好，但由于某种原因，它抛出一个异常，当跨入或超过这行代码。

如果调试器步骤进入Home控制器，索引操作方法和索引视图，那么为什么它突然抛出异常，它找不到Home路径"~/Home"的Home控制器?

捕获的fiddler数据可以在以下链接中找到:http://d-h.st/IqV

我已经使用Razor Generator来编译我的视图，我也在使用Ninject。Mvc来解析我的控制器。值得一提的是，我已经清除并重新生成了编译后的视图，并且我的项目不包含任何注册区域。

知道的吗?这可能是一个简单或明显的一个，但我是新的MVC和阅读/学习，因为我去。

谢谢

Answer 1

所以人们可以看到这个问题的答案，这里是为什么它抛出异常和我如何修复它:

由于HomeController Index视图中的以下代码行而抛出异常:

<a href="@Html.Action("Log Out","Logout", "Authentication")"><i class="icon-key"></i> Log Out</a> 

正如你所看到的，它传递了错误的参数，"Log Out"作为动作名称被传递进来，而实际上这应该是"Logout"。我把它更正为以下内容，它工作了:

<a href="@Html.Action("Logout", "Authentication")"><i class="icon-key"></i> Log Out</a> 

所以如果你得到这个异常，像我一样不能理解为什么那么请确保你检查你的代码在你的视图，以确保它是正确的。在这个例子中，框架没有提供一个含义异常消息和stacktrace。
