asp.net-mvc - 路径 '/Home' 的 Controller 未找到或未实现 IController

Question

我在互联网上到处搜索，并检查了所有以前回答过的具有相同标题的问题，但我无法弄清楚这个问题。

我从身份验证 Controller 中的操作方法返回 RedirectToAction("Index", "Home")，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.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: The controller for path '/Home' was not found or does not implement IController.

Source Error:

身份验证 Controller 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());
    }
}

请参阅下面我的 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 对于路由 {controller}/{action} 和 {*catchall} 返回 TRUE，并确认 AppRelativeCurrentExecutionFilePath 为:~/Home

我已经调试了代码，并且可以成功调试并单步执行 HomeController 构造函数和 Index 操作方法。我还能够进入“~/Views/Home/Index.cshtml”，但是它在代码行抛出异常:

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

有趣的是，在我进入这段代码之前，我可以将“@Model.UserName”添加到我的 watch 列表中，我可以很好地看到该对象及其属性，但由于某种原因，它在进入或超越时会引发异常这行代码。

如果调试器进入 HomeController、Index 操作方法和 Index View ，那么为什么会突然抛出找不到路径“~/Home”的 HomeController 的异常？

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

我已经使用 Razor Generator 来编译我的 View ，并且我还使用 Ninject.Mvc 来解析我的 Controller 。还值得一提的是，我已经清除并重新生成了编译的 View ，并且我的项目不包含任何注册区域。

有什么想法吗？这可能很简单，也可能很明显，但我是 MVC 新手，并且正在阅读/学习。

谢谢

Answer 1

所以人们可以看到这个问题在这里得到了回答，这就是为什么它抛出异常以及我如何修复它:

由于 HomeController Index View 中的以下代码行而引发异常:

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

正如您所看到的，它传递了错误的参数，并且“Log Out”作为操作名称传入，而实际上这应该是“Logout”。我将其更正为以下内容并且有效:

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

因此，如果您遇到此异常并且像我一样无法理解原因，那么请确保检查 View 中的其余代码以确保其正确。在这种情况下，框架不提供有意义的异常消息和堆栈跟踪。
