IdentityServer4客户端 - 刷新访问令牌上CookieAuthenticationEvents [英] IdentityServer4 client - Refreshing access tokens on CookieAuthenticationEvents

问题描述

我正在尝试在访问令牌到期时使用刷新令牌.类似这样的问题时回答 href="https://stackoverflow.com/a/41557598/3501052">.还有续订令牌的示例代码动作

I am trying to use refresh token when the access token expires. A similar so question is answered here. And a sample code to renew token by an action

和i相在startup.cs以下代码结束

And i end up with the following code in the startup.cs

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AuthenticationScheme = "Cookies",
    //ExpireTimeSpan = TimeSpan.FromSeconds(100),
    AutomaticAuthenticate = true,
    AutomaticChallenge = true,
    Events = new CookieAuthenticationEvents()
    {
        OnValidatePrincipal = async x =>
        {
            if (x.Properties?.Items[".Token.expires_at"] == null) return;

            var logger = loggerFactory.CreateLogger(this.GetType());

            var now = DateTimeOffset.UtcNow;
            var tokenExpireTime = DateTime.Parse(x.Properties.Items[".Token.expires_at"]).ToUniversalTime();
            var timeElapsed = now.Subtract(x.Properties.IssuedUtc.Value);
            var timeRemaining = tokenExpireTime.Subtract(now.DateTime);

            if (timeElapsed > timeRemaining)
            {
                var httpContextAuthentication = x.HttpContext.Authentication;//Donot use the HttpContext.Authentication to retrieve anything, this cause recursive call to this event
                var oldAccessToken = await httpContextAuthentication.GetTokenAsync("access_token");
                var oldRefreshToken = await httpContextAuthentication.GetTokenAsync("refresh_token");
                logger.LogInformation($"Refresh token :{oldRefreshToken}, old access token:{oldAccessToken}");


                var disco = await DiscoveryClient.GetAsync(AuthorityServer);
                if (disco.IsError) throw new Exception(disco.Error);

                var tokenClient = new TokenClient(disco.TokenEndpoint, ApplicationId, "secret");
                var tokenResult = await tokenClient.RequestRefreshTokenAsync(oldRefreshToken);
                logger.LogInformation("Refresh token requested. " + tokenResult.ErrorDescription);


                if (!tokenResult.IsError)
                {

                    var oldIdToken = await httpContextAuthentication.GetTokenAsync("id_token");
                    var newAccessToken = tokenResult.AccessToken;
                    var newRefreshToken = tokenResult.RefreshToken;

                    var tokens = new List<AuthenticationToken>
                    {
                        new AuthenticationToken {Name = OpenIdConnectParameterNames.IdToken, Value = oldIdToken},
                        new AuthenticationToken {Name = OpenIdConnectParameterNames.AccessToken, Value = newAccessToken},
                        new AuthenticationToken {Name = OpenIdConnectParameterNames.RefreshToken, Value = newRefreshToken}
                    };

                    var expiresAt = DateTime.UtcNow + TimeSpan.FromSeconds(tokenResult.ExpiresIn);
                    tokens.Add(new AuthenticationToken { Name = "expires_at", Value = expiresAt.ToString("o", CultureInfo.InvariantCulture) });

                    var info = await httpContextAuthentication.GetAuthenticateInfoAsync("Cookies");
                    info.Properties.StoreTokens(tokens);
                    await httpContextAuthentication.SignInAsync("Cookies", info.Principal, info.Properties);

                }
                x.ShouldRenew = true;
            }
            else
            {
                logger.LogInformation("Not expired");
            }
        }

    }
});

在客户机设置如下

AllowAccessTokensViaBrowser = true,
RefreshTokenUsage = TokenUsage.ReUse,
RefreshTokenExpiration = TokenExpiration.Sliding,
AbsoluteRefreshTokenLifetime = 86400,    
AccessTokenLifetime = 10,
AllowOfflineAccess = true,
AccessTokenType = AccessTokenType.Reference

成功登录后，我收到其他所有请求的401.和日志说:

After successfully login, i am getting a 401 for every other request. And the log says

任何帮助将通过高度赞赏

Any help would by highly appreciated

<强>更新:

基本上，当令牌过期我得到一个上下面的行

Basically, when the token expires i get a System.StackOverflowException on the following line

var tokenExpireTime = DateTime.Parse(x.Properties.Items[".Token.expires_at"]).ToUniversalTime();

更新2 : 的不使用HttpContext.Authentication检索任何的.检查我的回答下面找到工作implementaion

UPDATE 2: Do not use HttpContext.Authentication to retrieve anything. Check my answer below to find the working implementaion

推荐答案

我在做这个的最后两天，无法使这项工作.有趣地，在这里张贴的问题后，2小时内我做它的工作:)

I was working on this for last two days and could not make this work. Funnily, after posting the question here, within 2 hours I make it working :)

Events = new CookieAuthenticationEvents()
{
    OnValidatePrincipal = async x =>
    {
        if (x.Properties?.Items[".Token.expires_at"] == null) return;
        var now = DateTimeOffset.UtcNow;

        var tokenExpireTime = DateTime.Parse(x.Properties.Items[".Token.expires_at"]).ToUniversalTime();
        var timeElapsed = now.Subtract(x.Properties.IssuedUtc.Value);
        var timeRemaining = tokenExpireTime.Subtract(now.DateTime);
        WriteMessage($"{timeRemaining} and elapsed at {timeElapsed}");
        if (timeElapsed > timeRemaining)
        {
            var oldAccessToken = x.Properties.Items[".Token.access_token"];

            var oldRefreshToken = x.Properties.Items[".Token.refresh_token"];
            WriteMessage($"Refresh token :{oldRefreshToken}, old access token {oldAccessToken}");

            var disco = await DiscoveryClient.GetAsync(AuthorityServer);
            if (disco.IsError) throw new Exception(disco.Error);

            var tokenClient = new TokenClient(disco.TokenEndpoint, ApplicationId, "secret");
            var tokenResult = await tokenClient.RequestRefreshTokenAsync(oldRefreshToken);

            if (!tokenResult.IsError)
            {
                var oldIdToken = x.Properties.Items[".Token.id_token"];//tokenResult.IdentityToken

                var newAccessToken = tokenResult.AccessToken;
                var newRefreshToken = tokenResult.RefreshToken;

                var tokens = new List<AuthenticationToken>
                {
                    new AuthenticationToken {Name = OpenIdConnectParameterNames.IdToken, Value = oldIdToken},
                    new AuthenticationToken {Name = OpenIdConnectParameterNames.AccessToken, Value = newAccessToken},
                    new AuthenticationToken {Name = OpenIdConnectParameterNames.RefreshToken, Value = newRefreshToken}
                };

                var expiresAt = DateTime.UtcNow + TimeSpan.FromSeconds(tokenResult.ExpiresIn);
                tokens.Add(new AuthenticationToken { Name = "expires_at", Value = expiresAt.ToString("o", CultureInfo.InvariantCulture) });

                x.Properties.StoreTokens(tokens);

                WriteMessage($"oldAccessToken: {oldAccessToken}{Environment.NewLine} and new access token {newAccessToken}");

            }
            x.ShouldRenew = true;
        }
    }
}

基本上，httpContextAuthentication.GetTokenAsync使其具有递归性，因此发生了StackOverflowException.

Basically httpContextAuthentication.GetTokenAsync make this recursive, for that reason StackOverflowException occured.

请让我知道，如果这实现了任何问题

Please let me know if this implementation has any issue
