商店不實施IUserRoleStore <TUser>

Question

我有我自己的自定義實體店用戶和實體店角色。我現在正在嘗試將用戶添加到角色。通過這樣做

public void CreateUser(RegisterBindingModel model, String roleName) 
    { 
     try 
     { 
      ApplicationRole role = null; 
      if (!UserRoleManager.RoleExists(roleName)) 
      { 
       role = new ApplicationRole() { Name = roleName, Id = Suid.NewSuid().ToString() }; 
       IdentityResult result = UserRoleManager.Create(role); 
      } 
      else 
      { 
       role = UserRoleManager.FindByName(roleName); 
      } 

      var user = new ApplicationUser() { UserName = model.Email, Email = model.Email }; 

      IdentityResult result1 = UserManager.Create(user, model.Password); 

      UserManager.AddToRole(user.Id, role.Id); 

     } 
     catch (Exception e) 
     { 
      throw new Exception(e.Message.ToString()); // I get an exception here saying, Store does not implement IUserRoleStore<TUser> 
     } 

    } 

之後，我實現了。我現在有這個功能

public Task<IList<string>> GetRolesAsync(TUser user) 
    { 

     throw new NotImplementedException(); 
    } 

我該如何實現它？我的意思是如何發送用戶擁有的角色？我完整的實體用戶存儲情況如下

public class EntityUserStore<TUser, TAccount> : IUserStore<TUser>, IUserPasswordStore<TUser>, IUserEmailStore<TUser> , IUserRoleStore<TUser> 
    where TUser : class, IApplicationUser<TAccount>, new() 
    where TAccount : EntityModel, new() 
{ 
    public async Task CreateAsync(TUser user) 
    { 
     TableHelper.Save<TAccount>(user.Account); 
     EntityIndex.Set<TAccount>(user.UserName, user.Account); 
    } 

    public Task DeleteAsync(TUser user) 
    { 
     throw new NotImplementedException(); 
    } 

    public void Dispose() 
    { 

    } 

    public async Task<TUser> FindByIdAsync(string userId) 
    { 
     TAccount account = TableHelper.Get<TAccount>(userId); 

     if (account == null) 
      return null; 

     return new TUser() 
     { 
      Account = account 
     }; 

    } 

    public async Task<TUser> FindByNameAsync(string userName) 
    { 
     TAccount account = EntityIndex.Get<TAccount>(userName); 

     if (account == null) 
      return null; 

     return new TUser() 
     { 
      Account = account 
     }; 
    } 

    public Task UpdateAsync(TUser user) 
    { 
     throw new NotImplementedException(); 
    } 

    public async Task SetPasswordHashAsync(TUser user, string passwordHash) 
    { 
     user.PasswordHash = passwordHash; 

    } 

    public async Task<string> GetPasswordHashAsync(TUser user) 
    { 
     return user.PasswordHash; 
    } 

    public async Task<bool> HasPasswordAsync(TUser user) 
    { 
     return user.PasswordHash != null; 
    } 

    public async Task SetEmailAsync(TUser user, string email) 
    { 
     user.Email = email; 
    } 

    public async Task<string> GetEmailAsync(TUser user) 
    { 
     return user.Email; 
    } 

    public Task<bool> GetEmailConfirmedAsync(TUser user) 
    { 
     throw new NotImplementedException(); 
    } 

    public Task SetEmailConfirmedAsync(TUser user, bool confirmed) 
    { 
     throw new NotImplementedException(); 
    } 

    public async Task<TUser> FindByEmailAsync(string email) 
    { 
     TAccount account = EntityIndex.Get<TAccount>(email); 

     if (account == null) 
      return null; 

     return new TUser() 
     { 
      Account = account 
     }; 
    } 

    public Task AddToRoleAsync(TUser user, string roleName) 
    { 
     throw new NotImplementedException(); 
    } 

    public Task RemoveFromRoleAsync(TUser user, string roleName) 
    { 
     throw new NotImplementedException(); 
    } 

    public Task<IList<string>> GetRolesAsync(TUser user) 
    { 

     throw new NotImplementedException(); 
    } 

    public Task<bool> IsInRoleAsync(TUser user, string roleName) 
    { 
     throw new NotImplementedException(); 
    } 
} 

我現在想這個

public Task<IList<string>> GetRolesAsync(TUser user) 
    { 
     List<string> roles = new UserManager<TUser>(this).GetRoles(user.Id).ToList(); 
     return Task.FromResult((IList<string>)roles); 
    } 

但它無法正常工作。我正在超時例外。

Answer 1

您的EntityUserStore是Generic class和TUser不是類，它只是一種變量，將在編譯時用類User類替換。

所以如果你想獲得角色列表（特別是查看），你應該在你的控制器中獲得真正的類。

Answer 2

只需將實現以下接口IUserRoleStore<TUser>如下：

public class EntityUserStore<TUser, TAccount> : IUserStore<TUser>, 
IUserPasswordStore<TUser>, 
IUserEmailStore<TUser> , IUserRoleStore<TUser>, IUserRoleStore<TUser> 

這就強制你實現以下方法的具體實現;

public Task AddToRoleAsync(TUser user, string roleName) 
    { 
     throw new NotImplementedException(); 
    } 

    public Task RemoveFromRoleAsync(TUser user, string roleName) 
    { 
     throw new NotImplementedException(); 
    } 

    public Task<IList<string>> GetRolesAsync(TUser user) 
    { 
     throw new NotImplementedException(); 
    } 

    public Task<bool> IsInRoleAsync(TUser user, string roleName) 
    { 
     throw new NotImplementedException(); 
    } 

您只需針對您的數據源提供每種方法的實現。

的第一個的簡化的例子可以是如下（取決於你的數據上下文等）：

public Task AddToRoleAsync(TUser user, string roleName) 
    { 
     var roleToAdd = _context.Roles.FirstOrDefault(r => r.Name == roleName); 
     user.Roles.Add(roleToAdd); 
     return _context.SaveChangesAsync(); 
    }

在這裏從斯圖爾特韭菜leeksnet.AspNet.Identity.TableStorage發佈例如這是你正在努力實現的一個例子。
