遍历多个tomcat日志文件,找出含有ERROR 和Exception 的日志,并把该行日志输出到另一个文件中:(这里为了体现python模块导入的知识,所有建立了多个文件夹和模块)

项目结构:

consetting.py:
# 日志文件目录
F_PATH = r'C:\Users\shenping\PycharmProjects\Shenping_TEST\day_5\script\glive\logs'
# 错误日志存储目录
D_PATH = r'C:\Users\shenping\PycharmProjects\Shenping_TEST\day_5\script\glive\data'



rwfile.py:
def op_file(filename,content =None):
f = open(filename,'a+',encoding='utf-8')
f.seek(0)
if content:
f.writelines(content)
res = None
else:
res = f.readlines()
f.close()
return res


operationlog.py:
import re,os,datetime
from lib.rwfile import op_file # 遍历日志文件:
# 找出含有 error 或 exception 的行,按格式写入文件
def operation_log(filename,f_path,d_path):
index = 0
log_file = os.path.join(f_path, filename)
f = op_file(log_file)
lis = [] # 存储错误日志
for j in f:
index += 1
m = re.search('error',j,re.IGNORECASE)
n = re.search('exception',j,re.IGNORECASE)
if m or n:
data_file = os.path.join(d_path, str(datetime.date.today())+'_tomcat.log')
log_str = "文件名:"+filename+" 第"+str(index)+"行:"+j+'\n'
lis.append(log_str)
op_file(data_file,lis)
 

 start.py:

# 启动文件
import os,sys cur_path = os.path.abspath(__file__)
base_dir = os.path.dirname(os.path.dirname(cur_path))
sys.path.insert(0,base_dir)
from conf.consetting import F_PATH,D_PATH
from lib.operationlog import operation_log log_name = os.listdir(F_PATH)
for x in log_name:
operation_log(x,F_PATH,D_PATH)
print('========================================华丽的分割线=========================================================')

运行后结果:
