MVC登录模糊动作 [英] MVC Ambiguous Action for Login
问题描述
我有一个ASP.NET MVC4网站(使用vs2012)，该网站允许用户通过单击登录"链接进行登录.我收到了臭名昭著的错误:
I've got an ASP.NET MVC4 website (using vs2012) that allows users to login by clicking the "login" link. I'm getting the infamous error:
The current request for action 'Login' on controller type 'AccountController' is ambiguous between the following action methods:
System.Web.Mvc.ActionResult Login() on type MyProject.Controllers.AccountController
System.Web.Mvc.ActionResult Login(MyProject.Clients) on type MyProject.Controllers.AccountController
The current request for action 'Login' on controller type 'AccountController' is ambiguous between the following action methods:
System.Web.Mvc.ActionResult Login() on type MyProject.Controllers.AccountController
System.Web.Mvc.ActionResult Login(MyProject.Clients) on type MyProject.Controllers.AccountController
我在这里检查了很多链接，包括:
I've checked a bunch of links on here, including:
解决歧义 由于某些原因而导致的歧义操作方法调用. NET MVC 3
以及SO之外的其他一些内容.我确定我的方法装饰正确，但是仍然找不到发生这种情况的原因.
and a few more outside of SO. I've made sure I have the methods decorated correctly but still can't find the reason this is happening.
这是我的登录"链接的代码:
Here's my code for the "Login" link:
<ul class="topnav navRight">
@if (!User.Identity.IsAuthenticated)
{
<li><a href="@Url.Action("Login", "Account")" id="ViewLogin">LOGIN</a></li>
}
else
{
<li><a href="@Url.Action("Index", "ClientStats")">STATS</a></li>
<li><a href="@Url.Action("LogOut", "Account")">LOGOUT</a></li>
}
</ul>
和我的控制器:
[Authorize]
public class AccountController : CustomController
{
//
// GET: /Account/Logout
public ActionResult LogOut()
{
WebSecurity.Logout();
return RedirectToAction("Index", "Home");
}
[AllowAnonymous]
public virtual ActionResult Login()
{
return View();
}
[HttpPost]
[AllowAnonymous]
public virtual ActionResult Login(Clients model)
{
if (ModelState.IsValid)
{
Security security = new Security();
if (WebSecurity.Login(model.Username, model.Password))
{
using (MyProjectContext db = new MyProjectContext())
{
int userID = WebSecurity.GetUserId(model.Username);
Data.User user = db.Users.Find(userID);
if (user != null)
if (user.Active)
{
if (User.IsInRole("Administrator"))
return RedirectToAction("Admin", "ClientStats");
else
return RedirectToAction("Index", "ClientStats");
}
}
}
}
ModelState.AddModelError("", "Invalid Username or Password.");
return View(model);
}
}
CustomerController并没有什么特别之处，但无论如何都如此:
The CustomerController has nothing special in it but here it is anyways:
public class CustomController : Controller
{
public enum PageNames
{
Home,
Services,
Testimonials,
Video,
Photo,
FAQ,
About,
Contact,
Events,
Profile
}
public int UserId
{
get { return Convert.ToInt32(Session["UserId"]); }
set { Session["UserId"] = value; }
}
public static string GetPageTitle(PageNames pageName)
{
string pageTitle = "Welcome to My Website!";
switch (pageName)
{
case PageNames.Services:
pageTitle = "- Services";
break;
case PageNames.Testimonials:
pageTitle = "- Testimonials";
break;
case PageNames.Video:
pageTitle = "- Videos";
break;
case PageNames.Photo:
pageTitle = "- Photos";
break;
case PageNames.FAQ:
pageTitle = "- Frequently Asked Questions";
break;
case PageNames.Contact:
pageTitle = "- Contact Us";
break;
case PageNames.Events:
pageTitle = "- Calnedar of Events";
break;
case PageNames.Profile:
pageTitle = "- Profile";
break;
}
return pageTitle;
}
public static Data.User ClientInfo { get; set; }
}
这是路由信息...我试图取消注释一条路由(并更改了它的名称)，但是我仍然遇到相同的错误:
And here's the routing information...I've tried to uncomment the one route (and changed it's name) but I still get the same error:
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}",
defaults: new { controller = "Home", action = "Index" }
);
//routes.MapRoute(
// name: "Default",
// url: "{controller}/{action}/{id}",
// defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional }
//);
routes.MapRoute(
name: "id",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
非常感谢您的帮助/指导！
Any help/guidance is greatly appreciated!
更新我已经尝试了注释路由值并将[HttpGet]添加到Login方法的建议，但仍然会引发相同的错误.我确实记得一次可以完成这项工作，所以我不知道最近发生了什么变化以使其突然执行此操作.可能是Web.Config中的内容吗?
UPDATE I've tried the suggestions of commenting out the routing values and adding [HttpGet] to the Login method but it still throws the same error. I do recall this working at one time so I don't know what has changed lately to make it do this all of a sudden. Could it be something in the Web.Config?
推荐答案
MVC不支持仅基于签名的方法重载 删除[AllowAnonymous]
MVC doesn't support method overloading based solely on signature take [AllowAnonymous] out
在get actionresult中添加[HttpGet]并应解决问题
add a [HttpGet] to the get actionresult and the problem should be solved
[HttpGet]
public virtual ActionResult Login()
{
return View();
}
