Hangzhou Citizen Card failed to parse apptoken

The failure of Hangzhou Citizen Card to parse the apptoken may be caused by the following reasons:

1. The validity period of the apptoken has expired, and you need to obtain the apptoken again and try to parse again.

2. The format of the apptoken is incorrect. You need to confirm whether the token conforms to the standard format used, such as the JWT format.

3. The signature verification of apptoken fails, which may be caused by the token being tampered with. A digital signature or encryption algorithm needs to be used to protect the integrity of the token.

It is recommended that you check these aspects to ensure that the validity period, format and signature of the apptoken are correct, and try to obtain the apptoken again and then parse it.
