Apprendre à créer des WebSecurity.Login et WebSecurity.CreateUserAndAccount méthodes MVC 4?

Vous aurez besoin pour réaliser ses propres Membres et le Rôle des fournisseurs.

Fournisseur Personnalisé:

namespace MyApp.Helpers
{
    public class CustomProviderProvider : SimpleMembershipProvider
    {
        public override MembershipUser GetUser(string username, bool userIsOnline)
        {
            return base.GetUser(username, userIsOnline);
        }

        public override bool ValidateUser(string username, string password)
        {
            return true; //base.ValidateUser(username, password);
        }
    }
}

Vous aurez juste besoin de remplacer les méthodes que vous voulez "intercepter" (c'est à dire ValidateUser). Vous devez également enregistrer le fournisseur dans le web.fichier de configuration:

<system.web>
    <membership defaultProvider="CustomMembershipProvider">
      <providers>
        <clear/>
        <add name="SimpleMembershipProvider" type="WebMatrix.WebData.SimpleMembershipProvider, WebMatrix.WebData" />
        <add name="CustomMembershipProvider" type="MyApp.Helpers.CustomMembershipProvider, MyApp" />
      </providers>
    </membership>
</system.web>

Vous devez également avoir un Filtre appelé "InitializeSimpleMembershipAttribute"

namespace CustomPortal.Filters
{
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
    public sealed class InitializeSimpleMembershipAttribute : ActionFilterAttribute
    {
        private static SimpleMembershipInitializer _initializer;
        private static object _initializerLock = new object();
        private static bool _isInitialized;

        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            //Ensure ASP.NET Simple Membership is initialized only once per app start
            LazyInitializer.EnsureInitialized(ref _initializer, ref _isInitialized, ref _initializerLock);
        }

        private class SimpleMembershipInitializer
        {
            public SimpleMembershipInitializer()
            {
                Database.SetInitializer<CustomPortalContext>(null);

                try
                {
                    using (var context = new CustomPortalContext())
                    {
                        if (!context.Database.Exists())
                        {
                            //Create the SimpleMembership database without Entity Framework migration schema
                            ((IObjectContextAdapter)context).ObjectContext.CreateDatabase();
                        }
                    }
//Here is where you give it your connection string name
                    WebSecurity.InitializeDatabaseConnection("CustomPortal", "UserProfile", "UserId", "EmailAddress", autoCreateTables: true);
                }
                catch (Exception ex)
                {
                    throw new InvalidOperationException("The ASP.NET Simple Membership database could not be initialized. For more information, please see http://go.microsoft.com/fwlink/?LinkId=256588", ex);
                }
            }
        }
    }
}

J'espère que cela aide...
