asp.net - 如何在 ASP.NET Core cookie 身份验证中注销所有用户？

Question

我正在使用带有 CookieAuthentication 的 ASP.NET Core MVC。有没有办法让所有用户一次注销？我尝试重置 IIS - 没有用。我尝试删除所有用户的 session (我使用数据库进行 session 存储) - 没有用。

有任何想法吗？

您可以使用 CookieAuthenticationOptions.SessionStore属性，用于在服务器端存储身份信息，以便您在需要时清除所有信息。

public void ConfigureServices(IServiceCollection services)
{
    MemoryCacheTicketStore memoryCacheTicketStore = new MemoryCacheTicketStore();
    services.AddSingleton<MemoryCacheTicketStore>(memoryCacheTicketStore);

    services.AddAuthentication().AddCookie(cfg =>
    {
        cfg.SessionStore = memoryCacheTicketStore;
    });
}

public class SessionController : Controller
{
    private readonly MemoryCacheTicketStore memoryCacheTicketStore;

    public SessionController(MemoryCacheTicketStore memoryCacheTicketStore)
    {
        this.memoryCacheTicketStore = memoryCacheTicketStore;
    }

    public Task ClearAllSession()
    {
        return memoryCacheTicketStore.ClearAll();
    }
}

public class MemoryCacheTicketStore : ITicketStore
{
    private const string KeyPrefix = "AuthSessionStore-";
    private IMemoryCache _cache;

    public MemoryCacheTicketStore()
    {
        _cache = new MemoryCache(new MemoryCacheOptions());
    }

    public async Task ClearAll()
    {
        _cache.Dispose();
        _cache = new MemoryCache(new MemoryCacheOptions());
    }

    public async Task<string> StoreAsync(AuthenticationTicket ticket)
    {
        var guid = Guid.NewGuid();
        var key = KeyPrefix + guid.ToString();
        await RenewAsync(key, ticket);
        return key;
    }

    public Task RenewAsync(string key, AuthenticationTicket ticket)
    {
        var options = new MemoryCacheEntryOptions();
        var expiresUtc = ticket.Properties.ExpiresUtc;
        if (expiresUtc.HasValue)
        {
            options.SetAbsoluteExpiration(expiresUtc.Value);
        }
        options.SetSlidingExpiration(TimeSpan.FromHours(1)); // TODO: configurable.

        _cache.Set(key, ticket, options);

        return Task.FromResult(0);
    }

    public Task<AuthenticationTicket> RetrieveAsync(string key)
    {
        AuthenticationTicket ticket;
        _cache.TryGetValue(key, out ticket);
        return Task.FromResult(ticket);
    }

    public Task RemoveAsync(string key)
    {
        _cache.Remove(key);
        return Task.FromResult(0);
    }
}
