my sample code shown below.

class TokenAuth(TokenAuth):
def check_auth(self, token, allowed_roles, resource, method):
    accounts = app.data.driver.db['people']
    return accounts.find_one({'token': token})

app = Eve(__name__,static_url_path='/static', auth = TokenAuth)

      MAIL_USERNAME = '<username>',
      MAIL_PASSWORD = '<password>'
)

 mail=Mail(app)
 socketio = SocketIO(app)


 def create_token(user):
  payload = {
      'sub': str(user['_id']),
      'iat': datetime.now(),
      'exp': datetime.now() + timedelta(days=14)
  }

token = jwt.encode(payload, TOKEN_SECRET)
return token.decode('unicode_escape')

def login_required(f):
   @wraps(f)
   def decorated_function(*args, **kwargs):
    if not request.headers.get('Authorization'):
        response = jsonify(error='Missing authorization header')
        response.status_code = 401
        return response

    payload = parse_token(request)

    if datetime.fromtimestamp(payload['exp']) < datetime.now():
        response = jsonify(error='Token has expired')
        response.status_code = 401
        return response

    g.user_id = payload['sub']

    return f(*args, **kwargs)
