用户刚刚登录

标签： asp.net authentication oauth asp.net-core asp.net-core-2.0

当用户刚刚登录时，我需要做一些逻辑。记住当前会话的最后一个连接日期，然后将最后一个连接日期更新为Now。

问题是我需要的事件应该在用户登录后仅发生一次。如果多次出现，真实“最后连接日期”将是用实际日期覆盖，不行......

我可以用它做什么？

我使用AzureAD身份验证。我使用了一个事件OnValidatePrincipal，但这个事件多次发生......

是否有适合这种情况的事件？

我的代码：

public void ConfigureServices(IServiceCollection services) {
// [...]
services
.AddDistributedMemoryCache()
.AddSession(options =>
{   // Set a short timeout for easy testing.
    options.Cookie.Name = ".MyApp.Session";
    options.IdleTimeout = TimeSpan.FromSeconds(10);
    options.Cookie.HttpOnly = true;
})
.AddAuthentication(options =>
{
    options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    options.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
})
.AddCookie(options =>
{
    options.Events = new CookieAuthenticationEvents
    {
        OnSignedIn = context =>
        {
            Console.WriteLine("OnSignedIn, context=" + context);
            return Task.FromResult(true);
        },
        OnValidatePrincipal = async context =>
        {
            var user = (ClaimsIdentity)context.Principal.Identity;
            if (user.IsAuthenticated)
            {
                var mySingletonUser = context.HttpContext.RequestServices.GetService<IUser>();
                var repository = context.HttpContext.RequestServices.GetService<ITableRepositories>();
                var lastConnectedOn = DateTime.UtcNow;
                var userId = user.Name;
                var myUser = await repository.GetAsync<Connection>(userId);
                context.HttpContext.Session.SetString(UserController.SessionKeyFormerConnetion, myUser.LastConnectedOn.ToLongDateString());

                Claim isAdminClaim = new Claim("IsAdmin", myUser.IsAdmin.ToString(), ClaimValueTypes.Boolean);
                user.AddClaim(isAdminClaim);

                myUser.LastConnectedOn = DateTime.UtcNow;
                var updatedUser = repository.InsertOrMergeAsync(new List<Connection> { myUser });
                // update user from DB to display on the GUI
                UpdateMySingletonUser(context.HttpContext.RequestServices, myUser);

Bellow是应用程序的调试日志，当用户注销然后再次登录时：

最有可能我需要记录它记录的时刻（两次，不幸的是:(）

Microsoft.AspNetCore.Authorization.DefaultAuthorizationService: Information: Authorization was successful for user: myUser@myOrg.net.
Microsoft.AspNetCore.Authorization.DefaultAuthorizationService: Information: Authorization was successful for user: myUser@myOrg.net.

哪个事件对应于该日志？
