如何使 Asp.Net Core Identity 与 OpenIdConnect 一起工作

Question

如何从 asp.net 核心项目重新生成 open id connect 自定义声明？

我已经设置了手动映射到声明类型名称，但有时我需要从事件 OnTicketRecieved 之外更新其他声明，即来自 controller，所以在那个阶段我确实需要以某种方式重新生成声明。 我通过以下方式设置了 openIdConnect：

        _services
            .AddAuthentication(options =>
            {
                options.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
                options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
                options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
                options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            })
            .AddOpenIdConnect(options =>
            {
                options.ClientId = clientId;
                options.ClientSecret = clientSecret;
                options.Authority = $"{baseAuthorityUrl}/{tenantId}";
                options.CallbackPath = new PathString(callBackPath);
                options.Scope.Add("email");
                options.Scope.Add("profile");

                options.TokenValidationParameters = new TokenValidationParameters
                {
                    NameClaimType = "name"
                };

                options.SaveTokens = true;
                options.GetClaimsFromUserInfoEndpoint = true;
                options.Events = new OpenIdConnectEvents
                {
                    OnRedirectToIdentityProvider = e =>
                    {

                        return Task.CompletedTask;
                    },
                    OnTicketReceived = e =>
                    {
                        e.Principal.Identities.First().AddClaim(new Claim(ClaimTypes.Name, e.Principal.FindFirstValue("name")));

                        return Task.CompletedTask;
                    }
                };
            })

我如何重新生成 controller 的声明？ 我在想只是以某种方式覆盖 signInManager.RefreshSignInAsync(user)。

Answer 1

如果要在初始登录后在控制器中添加声明，则应使身份验证管理器使用新身份：

if (HttpContext.User.Identity is ClaimsIdentity identity)
{

    identity.AddClaim(new Claim("userId", "1234"));
    await HttpContext.SignInAsync(
        CookieAuthenticationDefaults.AuthenticationScheme,
        new ClaimsPrincipal(HttpContext.User.Identity));
}

这是您可以在登录事件之外更新声明的方式。 update是一个controller的方法。

public async Task Update()
{
    AuthenticateResult authenticateResult = await HttpContext.AuthenticateAsync();

    // Make a copy of the principal so we can modify it's claims
    ClaimsPrincipal newPrincipal = new ClaimsPrincipal(User.Identity)
    ClaimsIdentity claimsIdentity = (ClaimsIdentity)newPrincipal.Identity;

    // Add/remove claims
    claimsIdentity.AddClaim(new Claim("name", "value"));
    Claim toRemove = claimsIdentity.Claims.FirstOrDefault(c => string.Equals(c.Type, "claimnametoremove", StringComparison.Ordinal));
    if (toRemove != null)
        claimsIdentity.RemoveClaim(toRemove);

    // If these aren't updated, calls to "User" will pull the old principal value
    HttpContext.User = newPrincipal;
    Thread.CurrentPrincipal = newPrincipal;

    // Sign in the user with the new principal to "refresh" our logged-in user
    await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, newPrincipal, authenticateResult.Properties);
}
