上篇文章給大家介紹了asp.net5中用戶認(rèn)證與授權(quán)(1)，基礎(chǔ)建立好了，緊接著就要?jiǎng)?chuàng)建對(duì)基礎(chǔ)類進(jìn)行操作的類，也就是實(shí)現(xiàn)基礎(chǔ)類的增刪改查當(dāng)然，為了使用asp.net5的認(rèn)證機(jī)制，這些都是通過特定的接口來實(shí)現(xiàn)的。
比如，對(duì)于角色來說，角色管理要實(shí)現(xiàn)的接口如下：
public interface IQueryableRoleStoreTRole> : IRoleStoreTRole>, IDisposable where TRole : class
{
IQueryableTRole> Roles { get; }
}
public interface IRoleStoreTRole> : IDisposable where TRole : class
{
TaskIdentityResult> CreateAsync(TRole role, CancellationToken cancellationToken);
TaskIdentityResult> DeleteAsync(TRole role, CancellationToken cancellationToken);
TaskTRole> FindByIdAsync(string roleId, CancellationToken cancellationToken);
TaskTRole> FindByNameAsync(string normalizedRoleName, CancellationToken cancellationToken);
Taskstring> GetNormalizedRoleNameAsync(TRole role, CancellationToken cancellationToken);
Taskstring> GetRoleIdAsync(TRole role, CancellationToken cancellationToken);
Taskstring> GetRoleNameAsync(TRole role, CancellationToken cancellationToken);
Task SetNormalizedRoleNameAsync(TRole role, string normalizedName, CancellationToken cancellationToken);
Task SetRoleNameAsync(TRole role, string roleName, CancellationToken cancellationToken);
TaskIdentityResult> UpdateAsync(TRole role, CancellationToken cancellationToken);
}
其實(shí)，也沒什么復(fù)雜，一個(gè)是獲得所有預(yù)定義角色的列表，另一個(gè)是關(guān)于角色的增刪改查而已,代碼如下：
public class HDRoleStoreTRole> : IQueryableRoleStoreTRole>
where TRole : HDRole, new()
{
/// summary>
/// 存儲(chǔ)所有預(yù)定義的角色
/// /summary>
private readonly Dictionarystring, TRole> _roles = new Dictionarystring, TRole>();
/// summary>
/// 所有角色
/// /summary>
public IQueryableTRole> Roles
{
get
{
if (_roles.Count == )
{
TRole role = new TRole();
role.Id = "admin";
role.Name = "管理員";
_roles.Add(role.Id, role);
role = new TRole();
role.Id = "user";
role.Name = "用戶";
_roles.Add(role.Id, role);
role = new TRole();
role.Id = "power";
role.Name = "大蝦";
_roles.Add(role.Id, role);
}
return _roles.Values.AsQueryable();
}
}
public TaskIdentityResult> CreateAsync(TRole role, CancellationToken cancellationToken)
{
_roles[role.Id] = role;
return Task.FromResult(IdentityResult.Success);
}
public TaskIdentityResult> 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 TaskTRole> FindByIdAsync(string roleId, CancellationToken cancellationToken)
{
if (_roles.ContainsKey(roleId))
{
return Task.FromResult(_roles[roleId]);
}
return Task.FromResultTRole>(null);
}
public TaskTRole> FindByNameAsync(string normalizedRoleName, CancellationToken cancellationToken)
{
return
Task.FromResult(
Roles.SingleOrDefault(r => String.Equals(r.Name, normalizedRoleName, StringComparison.OrdinalIgnoreCase)));
}
public Taskstring> GetNormalizedRoleNameAsync(TRole role, CancellationToken cancellationToken)
{
return Task.FromResult(role.Name);
}
public Taskstring> GetRoleIdAsync(TRole role, CancellationToken cancellationToken)
{
return Task.FromResult(role.Id);
}
public Taskstring> 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 TaskIdentityResult> UpdateAsync(TRole role, CancellationToken cancellationToken)
{
_roles[role.Id] = role;
return Task.FromResult(IdentityResult.Success);
}
}
可以看到，在第12行，我們的方法里直接寫死了角色列表，如果相結(jié)合具體的項(xiàng)目的話，我相信葉良辰有一百種方法從各種數(shù)據(jù)庫(kù)、配置文件等取得角色列表，而其他程序代碼卻基本不用更改。
當(dāng)然，asp.net5自帶的默認(rèn)實(shí)現(xiàn)實(shí)現(xiàn)了很多其他接口，這里為了最簡(jiǎn)單起見，只實(shí)現(xiàn)了最基本的。
