python - Django Rest Framework Token Authentication failure results in Pop up -

i using django rest framework token authentication. in case if call url, providing token (token aesdghfhkjdsajgaadsa) invalid or deleted, pop asking username , password. how can avoid pop up? need response

{"status": -1, "errors": "token expired"} 

i using custom token authentication given,

class expiringtokenauthentication(tokenauthentication):  def authenticate_credentials(self, key):     try:         token = self.model.objects.get(key=key)     except self.model.doesnotexist:         raise exceptions.authenticationfailed('invalid token')      if not token.user.is_active:         raise exceptions.authenticationfailed('user inactive or deleted')      # required time comparison     utc_now = datetime.utcnow()     utc_now = utc_now.replace(tzinfo=pytz.utc)      if token.created < utc_now - timedelta(hours=24):         token.delete()         raise exceptions.authenticationfailed('token has expired')      return token.user, token 

is there solution this?

i assume pop-up username/password generated http basic/digest authentication schemes? that's coming basicauthentication authentication class.

django rest framework iterate through authentication methods listed in default_authentication_classes unless have explicitly provided list in apiview.authentication_classes.
