数据的封装思想--单例模式的应用

. 获取日志的堆栈信息

'''
应用了python提供的traceback模块，traceback.format_exc
import traceback
def process(self,hostname,ssh_func):
    """
    执行命令，去获取主板
    :return:
    """
    info = {'status': True, 'data': None, 'error': None}
    try:
        content = ssh_func(hostname, 'sudo dmidecode -t1')
        data = self.parse(content)
        info['data'] = data
    except Exception as e:
        msg = traceback.format_exc()
        logger.log(msg)
        info['status'] = False
        info['error'] = msg
    return info

数据的封装思想

'''
将需要的信息封装成一个字典
class BaseResponse(object):
    def __init__(self):
        self.status = True
        self.data = None
        self.error = None

    @property
    def dict(self):
        return self.__dict__
        
def process():
    info = BaseResponse()
    try:
        info.status = True
        info.data = "sfdsdf"
    except Exception:
        pass
    return info.dict

result = process()
print(result)       # {'status': True, 'data': 'sfdsdf', 'error': None}
