Python logging日志模块+读取配置文件

1配置文件config.ini 

[log]
level=INFO
filepath=./log
logname=run.log

[master]
ip=127.0.0.1
port=8080

2.读取配置文件config_base.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import ConfigParser

class Config(object):
    def __init__(self, filename):
        self.filename = filename
        self.config = ConfigParser.ConfigParser()
        self.config.read(self.filename)

    #日志配置
    def read_log(self):
        self.level = self.config.get("log", "level")
        self.filepath = self.config.get("log", "filepath")
        self.logname = self.config.get("log", "logname")
    #ip端口配置    
    def read_master(self):
        self.ip = self.config.get("master", "ip")
        self.port = self.config.get("master", "port")

3.创建公共类PuplicUnt.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

'''
@note: 公共类
'''
class PublicManger(object):
    logger=None
    conf=None

4.初始化log文件设置

#!/usr/bin/env python
#-*- coding:UTF-8 -*-

import os, sys, logging
import logging.handlers
import time
from PublicUnt import PublicManger

#初始化日志配置文件
def init_log():
    PublicManger.conf.read_log()
    PublicManger.logger=logging.getLogger()
    PublicManger.logger.setLevel(PublicManger.conf.level)
   
    fh = logging.handlers.TimedRotatingFileHandler(os.path.join(PublicManger.conf.filepath, PublicManger.conf.logname), when = 'D', maxBytes=10*1024*1024， backupCount = 10)
    sh = logging.StreamHandler()

    formatter = logging.Formatter('%(asctime)s-%(module)s:%(filename)s-L%(levelname)s:%(message)s')
    fh.setFormatter(formatter)
    PublicManger.logger.addHandler(fh)
    PublicManger.logger.addHandler(sh)

TimedRotatingFileHandler(filename [,when [,interval [,backupCount]]])

filename 是输出日志文件名的前缀

when 是一个字符串的定义如下：
“S”: Seconds
“M”: Minutes
“H”: Hours
“D”: Days
“W”: Week day (0=Monday)
“midnight”: Roll over at midnight

interval 是指等待多少个单位when的时间后，Logger会自动重建文件，当然，这个文件的创建
取决于filename+suffix，若这个文件跟之前的文件有重名，则会自动覆盖掉以前的文件，所以
有些情况suffix要定义的不能因为when而重复。

backupCount 是保留日志个数。默认的0是不会自动删除掉日志。若设10，则在文件的创建过程中
库会判断是否有超过这个10，若超过，则会从最先创建的开始删除。

# -*- coding:utf-8 -*-

import logging
from logging.handlers import RotatingFileHandler

class Logger:
    @classmethod
    def getlogger(cls,log,level):
        logger = logging.getLogger()
        rotfh = RotatingFileHandler(log,maxBytes=10*1024*1024,backupCount=5)
        #sh = logging.StreamHandler()
        fmatter = logging.Formatter("%(asctime)s - %(filename)s [line:%(lineno)d] %(name)-10s:%(levelname)-8s %(message)s")
        rotfh.setFormatter(fmatter)
        logger.addHandler(rotfh)
        logger.setLevel(level)
        Logger.logging = logger

 RotatingFileHandler(os.path.join(filepath,logname),maxBytes=10*1024*1024,backupCount=5)   按日志文件大小保留

from log import Logger

Logger.getlogger('./log/test1', 'INFO')
Logger.logging.info('hello')

 

5.写入日志

from config_base import Config
from initconf import init_log
from PublicUnt import PublicManger

CONFIG_FILE = "./config.ini"

def main():
    PublicManger.conf = Config(CONFIG_FILE)
    init_log()

if __name__ == '__main__':
    main()
    PublicManger.logger.info('save logging')

aa.写入配置文件

import ConfigParser

class Configer:
    @classmethod
    def load(cls,path):
        conf = ConfigParser.SafeConfigParser(allow_no_value=True)
        conf.read(path)
        items = conf.sections()
        opts = {}
        for item in items:
            opt = dict(conf.items(item))   
            opts = dict(opts,**opt)   #合并字典
        Configer.confs = opts

    @classmethod
    def update(cls,path,sec):
        conf = ConfigParser.ConfigParser(allow_no_value=True)
        conf.read(path)
        #for k,v in sec[1].iteritems():
        #    print k,v
        for key in sec[1]:
            conf.set(sec[0],key,sec[1][key])
        with open(path,'w') as cfile:
            conf.write(cfile)
        cls.load(path)

 

import Configer
import Logger

ip = ip = Configer.confs["ip"]
log = Logger.logging
log.info("ip is %s" %ip)

# -* - coding: UTF-8 -* -  
import ConfigParser

conf = ConfigParser.ConfigParser()
conf.read("c:\\test.conf")

# 获取指定的section， 指定的option的值
name = conf.get("section1", "name")
print(name)
age = conf.get("section1", "age")
print age

#获取所有的section  (log, master)
sections = conf.sections()
print sections

#写配置文件

# 更新指定section, option的值
conf.set("section2", "port", "8081")

# 写入指定section, 增加新option的值
conf.set("section2", "IEPort", "80")

# 添加新的 section
conf.add_section("new_section")
conf.set("new_section", "new_option", "http://www.cnblogs.com/tankxiao")

# 写回配置文件
conf.write(open("c:\\test.conf","w"))
