[英]MVC Exception: Ambiguous between the following action methods
I am getting this error. 我收到此错误。
The current request for action 'Login' on controller type 'AccountController' is ambiguous between the following action methods:
System.Web.Mvc.ActionResult Login(MVCApp.Models.Account) on type MVCApp.Controllers.AccountController
System.Web.Mvc.ActionResult SignIn(MVCApp.Models.Account) on type MVCApp.Controllers.AccountController
Here is my Code 这是我的代码
<input type="submit" name="Login" value="Login" />
<input type="submit" name="SignIn" value="SignIn" />
public class HttpParamActionAttribute : ActionNameSelectorAttribute
{
public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
{
if (actionName.Equals(methodInfo.Name, StringComparison.InvariantCultureIgnoreCase))
return true;
var request = controllerContext.RequestContext.HttpContext.Request;
return request[methodInfo.Name] != null;
}
}
public ActionResult Login()
{
return View();
}
[HttpPost]
[HttpParamAction]
public ActionResult Login(Account account)
{
Account createAccount = new Account();
createAccount.Username = account.Username;
createAccount.Email = account.Email;
createAccount.Password = account.Password;
return View("Login");
}
// GET: /Account/SignUp
public ActionResult SignIn()
{
return View();
}
[HttpPost]
[HttpParamAction]
public ActionResult SignIn(Account account)
{
Account createAccount = new Account();
createAccount.Username = account.Username;
createAccount.Email = account.Email;
createAccount.Password = account.Password;
return View("SignUp");
}
So you clicked the SignIn button which is routed to the Login action. 因此,您单击了“登录”按钮,该按钮被路由到“登录”操作。 The error is caused because HttpParamActionAttribute is returning true for IsValidName for both SignIn and Login actions. 引起该错误的原因是,对于SignIn和Login操作,IsValidName的HttpParamActionAttribute返回true。
Your HttpParamActionAttribute returns true for IsValidName against the Login action because the Login action matches by name. 您的HttpParamActionAttribute针对Login操作针对IsValidName返回true,因为Login操作按名称匹配。
Now your other HttpParamActionAttribute on SignIn also returns true because request["SignIn"] is not equal to null. 现在,您在SignIn上的其他HttpParamActionAttribute也返回true,因为request [“ SignIn”]不等于null。
Change your view to look for an action that is not "LogIn" and also not "SignIn". 更改视图以查找非“ LogIn”和“ SignIn”操作。 That way only the action that matches the button name will return true for IsValidName. 这样,只有与按钮名称匹配的操作才会为IsValidName返回true。
