CRecordSessionValidate

This record is needed when a session token we received from a user request is to be checked for validity. With the response we also receive the user ID and a list with the rights of the user.

This message belongs to the session manager API.

Example of use of the class CRecordSessionValidate (after generating)

You need the microservice ID of the session manager:

public static final IId SESSION_MICROSERVICE_ID = CIdFactory.fromObject("ccf168c1-f18b-4229-85f9-24461a19ee6a");

To validate a session token, we need the token the user received when he logged in.

private void validateToken(@Nullable final UUID aSessionToken) throws CException
{
    final CEnvelope env = CEnvelope.forMicroService(SESSION_MICROSERVICE_ID);

    final CRecord record = CRecordSessionValidate.create();
    CRecordSessionValidate.setToken(record,
                                    aSessionToken);

    aTarget.sendRequest(env,
                        record);
}

To catch the response of the request, we need a message handler. We add it in the constructor of the message handler registry.

// constructor:
addMessageHandler(CRecordSessionValidate.ID,
                  this::asyncSessionValidate);

private boolean asyncSessionValidate(@NotNull final CEnvelope aEnvelope,
                                     @NotNull final CRecord aRecord)
{
    if (aEnvelope.isAnswer())
    {
        final int resultCode = aEnvelope.getResultCode();
        if (resultCode == CResultCode.SUCCESS)
        {
            final UUID token = CRecordSessionValidate.getToken(aRecord,
                                                               null);
            final String userId = CRecordSessionValidate.getUserId(aRecord,
                                                                   null);
            final String[] rights = CRecordSessionValidate.getRights(aRecord,
                                                                     null);
            // ...
        }
        return true;
    }
    return false;
}
