網頁置換WatchDog實作測試

tags: Security

• 官方網站
  https://python-watchdog.readthedocs.io/en/stable/quickstart.html

• 環境準備
  安裝 pip
  https://www.delftstack.com/zh-tw/howto/linux/how-to-install-the-pip-package-manager-on-ubuntu/
  下載watchdog
  pip install -U watchdog

• 執行
  python3 watchdog2.py
  將會監控python執行檔案的區塊進行監控該區塊的所有跟sub dir進行監控異動
  可以額外增加參數，就可以指定該目錄底下所有檔案才會監測
  python3 watchdog2.py /home/xxx/subdir

以下是console呈現的結果:

xx@localhost:~/文件$ python3 watchdog2.py

• 改寫為log檔案產出

本次日誌改用append模式，寫入file，加料的字串是準備塞入主機名稱

import sys
import logging
from watchdog.observers import Observer
from watchdog.events import LoggingEventHandler

if __name__ == "__main__":
logging.basicConfig(level=logging.INFO, format='%(asctime)s, '+ '加料'+ ', %(message)s', datefmt='%Y-%m-%d %H:%M:%S',encoding='utf-8',filemode = 'a' , filename = 'monitor.csv')
path = sys.argv[1] if len(sys.argv) > 1 else '.'
event_handler = LoggingEventHandler()
observer = Observer()
observer.schedule(event_handler, path, recursive=True)
observer.start()
try:
while observer.is_alive():
observer.join(1)
finally:
observer.stop()
observer.join()

• 改寫增加監控的dir數量

• Error

Error 1 python執行檔案與watchdog lib同名
https://stackoverflow.com/questions/63219913/no-module-named-watchdog-observers-watchdog-is-not-a-package

Error 2 Sample Code有錯誤

import sys
import logging
from watchdog.observers import Observer
from watchdog.events import LoggingEventHandler

if __name__ == "__main__":
logging.basicConfig(level=logging.INFO,
format='%(asctime)s - %(message)s',
datefmt='%Y-%m-%d %H:%M:%S')
path = sys.argv[1] if len(sys.argv) > 1 else '.'
event_handler = LoggingEventHandler()
observer = Observer()
observer.schedule(event_handler, path, recursive=True)
observer.start()
try:
while observer.is_alive():  //這行有修正，從isAlive更正
observer.join(1)
finally:
observer.stop()
observer.join()

Error 2 ip抓到127.0.0.1

import socket
print(socket.gethostbyname(socket.gethostname()))
