简单的python日志类封装

---

最近学了下python的定制类相关，发现可以封装类进行链式调用，于是对Log类进行了封装

from enum import Enum

import logging

class AppLog:

    level = Enum('level',{'debug':logging.DEBUG,'info':logging.INFO,'warning':logging.WARNING,'error':logging.ERROR,'critical':logging.CRITICAL})

    logger = None

    lvl = None

    def __init__(self,name):

        self.logger = logging.getLogger(name)

        self.logger.setLevel(logging.DEBUG)

        self.setLogHandle()

    def setLogHandle(self):

        fhandler = logging.FileHandler('log/app.log','a','utf-8')

        formatter = logging.Formatter('%(asctime)s %(name)s %(levelname)s %(message)s')

        fhandler.setFormatter(formatter)

        fhandler.setLevel(logging.DEBUG)

        console = logging.StreamHandler()

        console.setFormatter(formatter)

        console.setLevel(logging.ERROR)

        self.logger.addHandler(fhandler)

        self.logger.addHandler(console)

    def __getattr__(self,name):

        if(name in ('debug','info','warn','error','critical')):

            self.lvl = self.level[name].value

            return self

        else:

            raise AttributeError('Attr not Correct') 

    def __call__(self,msg):

        self.logger.log(self.lvl,msg)

代码中使用了两个handler，其中debug级别及以上的Log会通过FileHandler写入当前目录下log/app.log文件下，error级别及以上的Log则会通过系统输出（ext://sys.stdout）的streamHandler在控制台进行输出

使用方法：如下直接调用即可

AppLog('test').error('xxx fail')

输出格式：

2018-07-16 12:41:17,185 test ERROR xxx fail
