ASP.NET5主要提供了两种应用程序,其一就是ASP.NET5控制台程序,另外一个是ASP.NET Web 应用程序。本文给大家介绍asp.net5中用户认证与授权(2),需要的童鞋可以参考下
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。
