How to create a active asm policy use rest api in v11.6.1?

Hi everyone,

I want to create a active asm policy use rest api, but it didn't work.

{u'code': 401, u'restOperationId': 52707, u'originalRequestBody': u'{"templateReference": {"link": ";}, "name": "rapid-4_asm_policy", "policyBuilderEnabled": false, "active": true, "applicationLanguage": "utf-8", "enforcementMode": "blocking"', u'referer': u'10.10.0.1', u'errorStack': [u'ASMConfigException(error_message:Policy must be applied and/or activated by a Task, error_code:ACTION_NOT_ALLOWED, internal_error:Failed set_active : Error message = Policy must be applied and/or activated by a Task, rest_code:REST_UNAUTHORIZED)'

here is my code:

!/usr/bin/env python
 -*- coding=utf-8 -*-
import requests
import json

requests.packages.urllib3.disable_warnings()


 创建LTM Policy
def create_ltm_policy_asm(bigip, ltm_policy_name, asm_policy_name):
