上篇文章给大家介绍了asp.net5中用户认证与授权(1)，基础建立好了，紧接着就要创建对基础类进行操作的类，也就是实现基础类的增删改查当然，为了使用asp.net5的认证机制，这些都是通过特定的接口来实现的。

比如，对于角色来说，角色管理要实现的接口如下：

public interface IQueryableRoleStore<TRole> : IRoleStore<TRole>, IDisposable where TRole : class { IQueryable<TRole> Roles { get; } } public interface IRoleStore<TRole> : IDisposable where TRole : class { Task<IdentityResult> CreateAsync(TRole role, CancellationToken cancellationToken); Task<IdentityResult> DeleteAsync(TRole role, CancellationToken cancellationToken); Task<TRole> FindByIdAsync(string roleId, CancellationToken cancellationToken); Task<TRole> FindByNameAsync(string normalizedRoleName, CancellationToken cancellationToken); Task<string> GetNormalizedRoleNameAsync(TRole role, CancellationToken cancellationToken); Task<string> GetRoleIdAsync(TRole role, CancellationToken cancellationToken); Task<string> GetRoleNameAsync(TRole role, CancellationToken cancellationToken); Task SetNormalizedRoleNameAsync(TRole role, string normalizedName, CancellationToken cancellationToken); Task SetRoleNameAsync(TRole role, string roleName, CancellationToken cancellationToken); Task<IdentityResult> UpdateAsync(TRole role, CancellationToken cancellationToken); }

其实，也没什么复杂，一个是获得所有预定义角色的列表，另一个是关于角色的增删改查而已,代码如下：

public class HDRoleStore<TRole> : IQueryableRoleStore<TRole> where TRole : HDRole, new() { /// <summary> /// 存储所有预定义的角色 /// </summary> private readonly Dictionary<string, TRole> _roles = new Dictionary<string, TRole>(); /// <summary> /// 所有角色 /// </summary> public IQueryable<TRole> Roles { get { if (_roles.Count == ) { TRole role = new TRole(); role.Id = "admin"; role.Name = "管理员"; _roles.Add(role.Id, role); role = new TRole(); role.Id = "user"; role.Name = "用户"; _roles.Add(role.Id, role); role = new TRole(); role.Id = "power"; role.Name = "大虾"; _roles.Add(role.Id, role); } return _roles.Values.AsQueryable(); } } public Task<IdentityResult> CreateAsync(TRole role, CancellationToken cancellationToken) { _roles[role.Id] = role; return Task.FromResult(IdentityResult.Success); } public Task<IdentityResult> DeleteAsync(TRole role, CancellationToken cancellationToken) { if (role == null || !_roles.ContainsKey(role.Id)) { throw new InvalidOperationException("Unknown role"); } _roles.Remove(role.Id); return Task.FromResult(IdentityResult.Success); } public void Dispose() { } public Task<TRole> FindByIdAsync(string roleId, CancellationToken cancellationToken) { if (_roles.ContainsKey(roleId)) { return Task.FromResult(_roles[roleId]); } return Task.FromResult<TRole>(null); } public Task<TRole> FindByNameAsync(string normalizedRoleName, CancellationToken cancellationToken) { return Task.FromResult( Roles.SingleOrDefault(r => String.Equals(r.Name, normalizedRoleName, StringComparison.OrdinalIgnoreCase))); } public Task<string> GetNormalizedRoleNameAsync(TRole role, CancellationToken cancellationToken) { return Task.FromResult(role.Name); } public Task<string> GetRoleIdAsync(TRole role, CancellationToken cancellationToken) { return Task.FromResult(role.Id); } public Task<string> GetRoleNameAsync(TRole role, CancellationToken cancellationToken) { return Task.FromResult(role.Name); } public Task SetNormalizedRoleNameAsync(TRole role, string normalizedName, CancellationToken cancellationToken) { role.Name = normalizedName; return Task.FromResult(); } public Task SetRoleNameAsync(TRole role, string roleName, CancellationToken cancellationToken) { role.Name = roleName; return Task.FromResult(); } public Task<IdentityResult> UpdateAsync(TRole role, CancellationToken cancellationToken) { _roles[role.Id] = role; return Task.FromResult(IdentityResult.Success); } }

可以看到，在第12行，我们的方法里直接写死了角色列表，如果相结合具体的项目的话，我相信叶良辰有一百种方法从各种数据库、配置文件等取得角色列表，而其他程序代码却基本不用更改。

当然，asp.net5自带的默认实现实现了很多其他接口，这里为了最简单起见，只实现了最基本的。
