写一个类读取以下配置{ "_id":"123131", "sid": "31313ddd", "appid":"dfafafafasdfa", "account_id":"gasfafa", "app_code": "appcode", "app_name": "新的应用", "app_status": 0, "flag": 0, "create_time": "2022-10-22 12:00:22", "update_time": "2022-10-22 12:00:22" }

这是一个 Python 类，可以用来读取上述配置：

class Config:
    def __init__(self, config_dict):
        self._id = config_dict["_id"]
        self.sid = config_dict["sid"]
        self.appid = config_dict["appid"]
        self.account_id = config_dict["account_id"]
        self.app_code = config_dict["app_code"]
        self.app_name = config_dict["app_name"]
        self.app_status = config_dict["app_status"]
        self.flag = config_dict["flag"]
        self.create_time = config_dict["create_time"]
        self.update_time = config_dict["update_time"]

config = Config({     "_id":"123131",     "sid": "31313ddd",     "appid":"dfafafafasdfa",     "account_id":"gasfafa",     "app_code": "appcode",     "app_name": "新的应用",     "app_status": 0,     "flag": 0,     "create_time": "2022-10-22 12:00:22",     "update_time": "2022-10-22 12:00:22" })

这样，你就可以通过 `config._id`、`config.sid` 等属性来访问配置中的各个字段了。
