在ASP MVC 5角色管理（Microsoft.AspNet.Identity） [英] Role Management in ASP MVC 5 (Microsoft.AspNet.Identity)

问题描述

在ASP MVC5 RC我没得到角色系统正常工作。
我的数据库有需要的所有表的角色存在，但如果打样用户在角色总是返回false（不SQL异常或东西）！？

in ASP MVC5 RC I didn't get the role system to work. My database has all needs tables an role exist but proofing if user is in role always return false (no SQL exception or something)!?

难道我需要激活角色系统的IPrincipal 地方？

Did I need to activate role system for IPrincipal somewhere?

测试code：

AccountController accCont = new AccountController();

// check role exist : result = true
var roleExist = await accCont.IdentityManager.Roles.RoleExistsAsync("61c84919-72e2-4114-9520-83a3e5f09de1");

// try find role by name : result = role object
var role = await accCont.IdentityManager.Roles.FindRoleByNameAsync("ProjectAdministrator");

// check with AccountController instance :  result = true
var exist = await accCont.IdentityManager.Roles.IsUserInRoleAsync(User.Identity.GetUserId(), role.Id);

// check if current user is in role : result (both) = false????
var inRole = User.IsInRole(role.Id);
var inRole2 = User.IsInRole(role.Name);

我也尝试建立像 Microsoft.AspNet.Identity.Owin IIdentity.GetUserId（）扩展方法的定制减轻罪责C $ C>命名空间。

I also try to build an custom extenuation like the IIdentity.GetUserId() extension method from Microsoft.AspNet.Identity.Owin Namespace.

namespace Microsoft.AspNet.Identity
{
   public static class IdentityExtensions
   {
       public static string IsUserInRole(this IIdentity identity)
       {
           if (identity == null)
           {
               throw new ArgumentNullException("identity");
           }
           ClaimsIdentity identity2 = identity as ClaimsIdentity;
           if (identity2 != null)
           {
               var result = identity2.FindFirstValue(IdentityConfig.Settings.GetAuthenticationOptions().RoleClaimType);

               return null; // later result
           }
           return null;
       }
   }
}

但结果对索赔类型 RoleClaimType 总是空 :(
我真的坚持这一点。

But the result for claim Type RoleClaimType is always null :( I'm really stuck with this.
