本模块是accounts，是否数据保存和读取，用json实现序列化和反序列化，其实以下代码可以合并优化的，本人偷懒就没有进行了，有兴趣的朋友可以自己优化
‘‘‘
def load(account):
    ‘‘‘
    该函数实现了将文件中的数据反序列化
    :param account: 信用卡账号信息
    :return:

    db_path = db_handler.db_handler(settings.DATABASE)
    db_file = "%s/%s.json"%(db_path,account)
    with open(db_file) as f:
        acc_data = json.load(f)
    return acc_data

def dump(account_data):
    ‘‘‘
    该函数实现了将传过来的数据序列化
    :param account_data: 信用卡用户信息，字典类型

    db_path = db_handler.db_handler(settings.DATABASE)
    db_file = "%s/%s.json" % (db_path, account_data["account"])
