定时任务调用的函数

def test():
    print("开始时间"+ ": " +(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())))
    obj = rabbitmqAPI()
    obj.check_rabbit_diff
    print("结束时间"+ ": " +(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())))

函数中调用的方法，变量有使用 current_app

def __init__(self):
    self.localtime = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
    self.url = current_app.config['URL']
    self.auth = (current_app.config['USERNAME'], current_app.config['PASSWORD'])
    self.datas = self.get_manager_datas()

def check_rabbit_diff(self):
    rabbit_name = self.add_wrong_data_to_sql()
    sql_name = self.get_allname_from_sql()
    diff_name = list(set(sql_name) ^ set(rabbit_name))

    if len(diff_name) != 0:
        for i in diff_name:
            Rabbitmq.update_data(i, self.localtime)

    return "Finish"

定时任务运行时，代码报错了：Working outside of application context
我要如何处理才能解决这个报错？
