1: 自定义日志文件.py----------几个文件需要创建日志,就需要重新定义几份
# 定义一个日志文件 创建一个操作日志对象logger file_1 = logging.FileHandler('text_1.log', 'a', encoding='utf-8') # text_1.log 定义日志文件名 fmt = logging.Formatter(fmt="%(asctime)s - %(name)s - %(levelname)s -%(module)s: %(message)s") # 定义创建时间,哪个文件,错误level,··
file_1 .setFormatter(fmt) # 建立执行 # 定义日志
logger1 = logging.Logger('s1', level=logging.ERROR) # 设置日志
logger1.addHandler(file_1 )
2:将定义好的定义日志导入需要存放报错的文件,并且使用traceback模块具体化报错地点:
# 导入模块
import logging
import traceback
# 导入定义好的日志变量
from Api.utils.自定义日志 import logger1 # 测试1:
def func():
try:
a = a + 1
except Exception as e:
msg = traceback.format_exc()
logger1.error(msg) func() #报错结果:(自动创建文件并且写入错误信息)
2019-11-26 14:25:10,196 - s1 - ERROR -logging2: Traceback (most recent call last):
File "C:/Users/user/Desktop/framework/django-rest-framework/Api/utils/logging2.py", line 17, in func
a = a + 1
UnboundLocalError: local variable 'a' referenced before assignment
3:直接定义logging(不推荐),需要创建多个日志文件:
import logging # logging
logging.basicConfig(
filename='loggingdemo.txt', # 日志文件名
format='%(asctime)s - %(name)s - %(levelname)s -%(module)s: %(message)s',
datefmt='%Y-%m-%d %H:%M:%S %p',
level=10
) logging.debug('None')
logging.info('None') # 正常的信息
logging.warning('None') # 警告(不出错)
logging.error('None') # 报错
logging.critical('None') # 非常严重的错误 # logging.log(10,'log') """
CRITICAL = 50
FATAL = CRITICAL
ERROR = 40
WARNING = 30
WARN = WARNING
INFO = 20
DEBUG = 10
NOTSET = 0
""" def func():
try:
a = a + 1
except Exception as e:
print(e)
logging.error(str(e))
func()
4:Django里指定任意日志文件位置:
# 取执行文件全局绝对路径(不管在哪里启动Django都会取到这个路径) 红色的字体表示自定义名称
path= os.path.abspath(os.path.dirname(__file__)) # 拼接路径
files_path = path + "/keywords_logging/文件名.log" # 路径+设定的日志文件名 # 设置日志
keyword_expect_debug = logging.FileHandler(files_path, 'a', encoding='utf-8')
fmt = logging.Formatter(fmt="%(asctime)s - %(name)s - %(levelname)s -%(module)s: %(message)s")
keyword_expect_debug.setFormatter(fmt) keyword_debug = logging.Logger('keyword_debug', level=logging.DEBUG)
keyword_debug.addHandler(keyword_expect_debug) # 定义文件日志
form 文件 import keyword_debug
try:
a = a + 1
except Exception as e:
msg = traceback.format_exc()
logging_main.keyword_debug.debug(msg)
