Question

我一直在摆弄IDS 4，但有一个小问题。我将令牌寿命设置为大约15秒，即使它们已过期，我仍然可以从资源服务器中检索日期。如果我从客户端调用的标头中删除令牌，则会收到401错误。

客户端

    [Authorize]
    public async Task<ActionResult> Shouts()
    {

        var accessToken = await HttpContext.GetTokenAsync("access_token");
        var tokenh = new JwtSecurityTokenHandler();

        var jwtSecurityToken= tokenh.ReadJwtToken(accessToken);

        var val = jwtSecurityToken.ValidTo;



        using (var client = new HttpClient())
        {

            client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", accessToken);
            var rawResponse = await client.GetAsync("http://localhost:5002/api/Values/Get");

            if (rawResponse.StatusCode == System.Net.HttpStatusCode.Unauthorized)
            {
                var refreshSucc = await this.RefreshTokensAsync(this.HttpContext);
                if (!refreshSucc)
                {
                    var authServerInfo = await this.GetAuthenticationServerInfo();
                    return Redirect(authServerInfo.AuthorizeEndpoint);
                }
            }

            var response = await (rawResponse).Content.ReadAsStringAsync();
            var data = JsonConvert.DeserializeObject<List<String>>(response);
            return View("Shouts", data);
        }
    }

Answer 1

尝试将Web api（资源服务器）中的options.JwtValidationClockSkew属性设置为零

   services.AddAuthentication("Bearer")
        .AddIdentityServerAuthentication(options =>
        {
            options.JwtValidationClockSkew = TimeSpan.Zero;
            options.Authority = "https://localhost:44323";
            options.RequireHttpsMetadata = false;

            options.ApiName = "api1";
        });

Microsoft JWT验证中间件中存在时钟偏斜。默认情况下设置为5分钟。建议将其保留为默认值（300秒/ 5分钟）。

Answer 2

这很可能是由于默认的5分钟（如果有内存的话）时钟偏移允许。但是，可以在IDS4和承载令牌中间件中覆盖此设置。
