当我们选择New Project – > MVC 4 – >互联网应用,它将自动为我们生成AccountController.在这个控制器中,我只关心2个操作,登录和注册.
在MVC 3中,它使用Membership的静态方法,ValidateUserin Login操作和CreateUser在Register中.所以,如果我想将它与我自己的数据库集成,我只需要创建CustomMembershipProvider通过扩展MembershipProvider并覆盖这两个方法.
但是在MVC 4中,它使用WebSecurity.Login和WebSecurity.CreateUserAndAccount.我的问题是：
>如何使用我自己的数据库,就像我在MVC 3中一样？
>有什么不同？为什么不继续使用静态会员方法？为什么要改变为WebSecurity？
非常感谢你的帮助.
解决方法
您将需要实现您自己的会员和角色提供商.
自定义提供者
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);
}
}
}
你只需要覆盖你想要“拦截”的方法(即ValidateUser).您还需要在web.config文件中注册提供程序：
<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>
你也应该有一个名为“InitializeSimpleMembershipAttribute”的过滤器
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);
}
}
}
}
}
我希望这有帮助…
