tornado 使用 corotine 如何获取 celery 返回值

@tornado.web.asynchronous
    @tornado.gen.coroutine
    @auth_token
    @log_record
    def post(self):
        """
        bussiness_name
        description
        :return:
        """
        resultCode = self.request.headers.get('resultCode', -1)
        resultData = self.request.headers.get('resultData', {})
        user_id = resultData['user_id']
        token = None
        data = {}
        body = json.loads(self.request.body)
        data['business_name'] = body['name']
        data['system_user_id'] = body['user_id']
        data['description'] = body['description']
        remote_call_result = get_business_result.apply_async(args=["POST", user_id, data])
        # response = remote_call_result.wait()
        # self.on_post_result(response)
        response = yield tornado.gen.Task(remote_call_result.wait())
        self.on_post_result(response)


    def on_post_result(self, response):
        di_result = json.dumps(response)
        logger.info("verify, result:%s \n" % di_result)
        self.write(json.dumps(di_result))
        self.finish()

代码如上，使用 yield gen.Task 无法获取获得的 response，celery 任务是一个 rpc call， 有什么方法可以异步来获取结果？
