Question

I use "bearer token" and i want once client post request to server include token,server will add "expires_in" time for this token.

EX : first "expires_in"=1800,after server get token from client, "expires_in_after"="expires_in"+1000.

Hi Ken.N,

According to your description, I suggest you can try the following code.

/// <summary>
        /// Updating existing Token validity
        /// </summary>
        /// <param name="Token"></param>
        /// <returns></returns>
        public HttpResponseMessage UpdateTokenTime(string Token)
        {
            //First Token decryption
            AuthenticationTicket ticket = Startup.OAuthOptions.AccessTokenFormat.Unprotect(Token);
            if (ticket != null && (ticket.Properties != null  && ticket.Properties.ExpiresUtc.HasValue ))
            {
                //Change the time - Increased 1000 seconds
                ticket.Properties.ExpiresUtc.Value.AddSeconds(1000);
            }
            //Token encryption protection
            string token = Startup.OAuthOptions.AccessTokenFormat.Protect(ticket);
            //Back token, the client saved.
            return new HttpResponseMessage(HttpStatusCode.OK)
            {
                Content = new ObjectContent<object>(new
                {
                    accessToken = token,
                    expiresIn = (int)((ticket.Properties.ExpiresUtc.Value - ticket.Properties.IssuedUtc.Value).TotalSeconds),
                }, Configuration.Formatters.JsonFormatter)
            };
        }

Hi Ken.N,

You can Compare deadline and the current time as the following method.

               if (ticket.Properties.ExpiresUtc.Value < DateTimeOffset.UtcNow)
                {
                     //Add 1000 seconds
                }
