配置loggin

#逻辑代码中配置

 1 import logging 
 2 
 3 # 1、创建一个logger 
 4 logger = logging.getLogger('mylogger') 
 5 logger.setLevel(logging.DEBUG) 
 6 
 7 # 2、创建一个handler，用于写入日志文件 
 8 fh = logging.FileHandler('log.log') 
 9 fh.setLevel(logging.DEBUG) 
10 
11 # 再创建一个handler，用于输出到控制台 
12 ch = logging.StreamHandler() 
13 ch.setLevel(logging.DEBUG) 
14 
15 # 3、定义handler的输出格式（formatter）
16 formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s') 
17 
18 # 4、给handler添加formatter
19 fh.setFormatter(formatter) 
20 ch.setFormatter(formatter) 
21 
22 # 5、给logger添加handler 
23 logger.addHandler(fh) 
24 logger.addHandler(ch)
