import logging
import os
import sys
获取logger实例，如果参数为空则返回root logger
import time
logger = logging.getLogger(“navigation”)
指定logger输出格式
formatter = logging.Formatter(
‘%(asctime)s - ProcessID:%(process)d - ThreadID:%(thread)d - ThreadName:%(threadName)s - %(filename)s - Func:%(funcName)s - len[%(lineno)d] : %(levelname)s %(message)s’)
文件日志
current_path = os.path.join(os.path.dirname(os.path.abspath(file)), ‘…/…/logs’, ‘info’)
if not os.path.exists(current_path):
os.makedirs(current_path, exist_ok=True)
file_handler = logging.FileHandler(
os.path.join(current_path, “{}-all.log”.format(time.strftime("%Y%m%d", time.localtime()))),
encoding=‘utf-8’)
file_handler.setFormatter(formatter) # 可以通过setFormatter指定输出格式
控制台日志
console_handler = logging.StreamHandler(sys.stdout)
console_handler.formatter = formatter # 也可以直接给formatter赋值
为logger添加的日志处理器
logger.addHandler(file_handler)
logger.addHandler(console_handler)
指定日志的最低输出级别，默认为WARN级别
logger.setLevel(logging.DEBUG)
