django-otp не генерирует новый токен после проверки токена

Question

Я использую "django-otp" в "Django DRF" для генерации и проверки токена OPT. Я использую генерацию и проверку токена TOTP, и мой токен составляет 50 секунд. Он генерирует тот же OTP-токен даже после проверки. Я использовал код в качестве ссылки: https://medium.com/viithiisys/creating-and-verifying-one-time-passwords-with-django-otp-861f472f602f Я хочу создать новый токен после проверки

МОЙ Код: класс TOTP Проверка:

def __init__(self):
    # secret key that will be used to generate a token,
    # User can provide a custom value to the key.
    self.key = random_hex(20)
    # counter with which last token was verified.
    # Next token must be generated at a higher counter value.
    self.last_verified_counter = -1
    # this value will return True, if a token has been successfully
    # verified.
    self.verified = False
    # number of digits in a token. Default is 6
    self.number_of_digits = 6
    # validity period of a token. Default is 30 second.
    self.token_validity_period = 35

def totp_obj(self):
    # create a TOTP object
    totp = TOTP(key=self.key,
                step=self.token_validity_period,
                digits=self.number_of_digits)
    # the current time will be used to generate a counter
    totp.time = time.time()
    return totp

def generate_token(self):
    # get the TOTP object and use that to create token
    totp = self.totp_obj()
    # token can be obtained with `totp.token()`
    token = str(totp.token()).zfill(6)
    return token

def verify_token(self, token, tolerance=0):
    try:
        # convert the input token to integer
        token = int(token)
    except ValueError:
        # return False, if token could not be converted to an integer
        self.verified = False
    else:
        totp = self.totp_obj()
        # check if the current counter value is higher than the value of
        # last verified counter and check if entered token is correct by
        # calling totp.verify_token()
        if ((totp.t() > self.last_verified_counter) and
                (totp.verify(token, tolerance=tolerance))):
            # if the condition is true, set the last verified counter value
            # to current counter value, and return True
            self.last_verified_counter = totp.t()
            self.verified = True
        else:
            # if the token entered was invalid or if the counter value
            # was less than last verified counter, then return False
            self.verified = False
    return self.verified
