How to verify whether the access token is expired or invalid?

[webyushao]

After obtaining access_token using getAuthToken method on node side, I want to know when the access_token will expire. May I ask which interface can I check?
My process is to get the access_token through getAuthToken and then get the userInfo through the parseJwtToken method.
