问题:

Hey guys I started playing around with the ASP.NET MVC 5 preview and everything has been going fine so far (I can only recommend it).

However, I wonder where I can set the Login-Url for the Built-In [Authorize]-Attribute. I've moved the AccountController to a an area, so the path to the Login action is no longer /Account/Login but MyArea/Account/Login, which is ignored by the [Authorize]-Attribute, which in turn means, that whenever one navigates to a controller or action with the attribute set, one is redirected to the wrong path /Account/Login.

回答1:

Look in web.config for a section like this:

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

Change the loginUrl value to point to your updated login page.

When using the new OWIN forms authentication (as opposed to the old ASP.NET forms authentication), this gets set in the Startup class. In the default templates, it's in App_Start/Startup.Auth.cs in the ConfigureAuth method:

public void ConfigureAuth(IAppBuilder app)
{
   app.UseCookieAuthentication(new CookieAuthenticationOptions
   {
      AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
      LoginPath = new PathString("/Account/Login")
   });
   app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
}
