Appium 学习： logging 日志管理

1.1 日志级别

import logging


"""
logging is filtered by division of information into different levels
DEBUG is the Basic level, While the CRITICAL is the highest level
"""

# logging.basicConfig(level=logging.DEBUG)
# logging.basicConfig(level=logging.INFO)

""" The output will be same, if WARN replace  WARNING """
# logging.basicConfig(level= logging.WRAN)
# logging.basicConfig(level=logging.WARNING)

# logging.basicConfig(level=logging.ERROR)
logging.basicConfig(level=logging.CRITICAL)


logging.debug('this is debug info')
logging.info('info is : hello you')
logging.warning('warning info')
logging.error('this is error info')
logging.critical('critical info')

• the output of level=logging.DEBUG *

DEBUG:root:this is debug info
INFO:root:info is : hello you
WARNING:root:warning info
ERROR:root:this is error info
CRITICAL:root:critical info

• the output of level=logging.CRITICAL *

ERROR:root:this is error info
CRITICAL:root:critical info

1.2 日志的格式

格式 描述
%(levelno)s 打印日志级别的数值
%(levelname)s 打印日志级别名称
%(pathname)s 打印当前执行程序的路径
%(filename)s 打印当前执行程序名称
%(funcName)s 打印日志的当前函数
%(lineno)d 打印日志的当前行号
%(asctime)s 打印日志的时间
%(thread)d 打印线程id
%(threadName)s 打印线程名称
%(process)d 打印进程ID
%(message)s 打印日志信息

在logging库中定义如下：

CRITICAL = 50
FATAL = CRITICAL
ERROR = 40
WARNING = 30
WARN = WARNING
INFO = 20
DEBUG = 10
NOTSET = 0

logging.basicConfig(level=logging.DEBUG,filename='../log/runlog.log',format='%(levelno)s %(asctime)s %(threadName)s %(filename)s %(lineno)d %(levelname)s  %(message)s')

the output

10 2018-12-05 16:38:00,982 MainThread log_practice.py 25 DEBUG  this is debug info
20 2018-12-05 16:38:00,982 MainThread log_practice.py 26 INFO  info is : hello you
30 2018-12-05 16:38:00,982 MainThread log_practice.py 27 WARNING  warning info
40 2018-12-05 16:38:00,982 MainThread log_practice.py 28 ERROR  this is error info
50 2018-12-05 16:38:00,982 MainThread log_practice.py 29 CRITICAL  critical info

1.3 日志参数配置分离

配置文件的理解！！！！, 学习一下
log.conf

[loggers]
keys=root,infoLogger

[logger_root]
level=DEBUG
handlers=consoleHandler,fileHandler

[logger_infoLogger]
handlers=consoleHandler,fileHandler
qualname=infoLogger
propagate=0

[handlers]
keys=consoleHandler,fileHandler

[handler_consoleHandler]
class=StreamHandler
level=INFO
formatter=form02
args=(sys.stdout,)

[handler_fileHandler]
class=FileHandler
level=INFO
formatter=form01
args=('../logs/runlog.log', 'a')

[formatters]
keys=form01,form02

[formatter_form01]
format=%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s

[formatter_form02]
format=%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s

调用

import logging
import logging.config


CON_LOG='log.conf'
logging.config.fileConfig(CON_LOG)
logging=logging.getLogger()
