Asp.Net Core & JWT authentication: How to know authentication failed because token expired?










0















The blow is JWT authentication I am using:



.AddJwtBearer(options =>

// options.SaveToken = false;
// options.RequireHttpsMetadata = false;

options.TokenValidationParameters = new TokenValidationParameters

ValidateIssuerSigningKey = true,
IssuerSigningKey = new SymmetricSecurityKey(AuthConfig.GetSecretKey(Configuration)),

ValidateIssuer = false,
ValidateAudience = false,

ValidateLifetime = true,
ClockSkew = TimeSpan.Zero,
;

options.Events = new JwtBearerEvents()

OnChallenge = c =>

c.HandleResponse();

// TODO: How to know if the token was expired?

return AspNetUtils.WriteJsonAsync(c.Response, new Result<string> Message = "Unauthenticated.", IsError = true
, 401);
,
;
)


The authentication is working fine. For new requirements, I need to know if authentication failed because the JWT token was expired or not.



Note that authentication failed can be multi reasons. The token can be missing, tampered, or expired.



Any ideas? Thanks!
